| 02:04 | <gnunux> hi
| |
| 02:11 | <Uzzi> highvoltage, i've to config grub2 (/boot/grub/grub.cfg) to boot with ltsp server, because my old pc cannot booting by LAN
| |
| 02:11 | ops sorry highvoltage I've to type only "hi"
| |
| 02:13 | <alkisg> Uzzi: do you have an ubuntu version installed on that pc?
| |
| 02:13 | <Uzzi> yes
| |
| 02:14 | <alkisg> Which one?
| |
| 02:14 | <Uzzi> 10.04 or 9.10
| |
| 02:15 | <alkisg> This package (I assume i386) installs gpxe to the grub2 boot loader: https://launchpad.net/~ts.sch.gr/+archive/ppa/+files/gpxe-grub_1.0.0%7E1%7Eppa1_all.deb
| |
| 02:15 | So it offers a "boot from network" menu
| |
| 02:15 | Verify that you have grub2 before installing it
| |
| 02:16 | (fresh 9.10 and 10.04 installations do use grub2 by default)
| |
| 02:17 | <Uzzi> very good alkisg thanks a lot
| |
| 02:17 | <alkisg> np
| |
| 02:22 | <Uzzi> alkisg, I've a"vergin" pc, can I install only grub2 in a small partition and after gpxe-grub?
| |
| 02:22 | <alkisg> Uzzi: to install grub2 you need to have an OS first
| |
| 02:22 | So no. But you can install gpxe in the same way that you'd install it on a usb stick
| |
| 02:23 | You have an empty local hard disk and you want to waste it all just to put gpxe on it?
| |
| 02:24 | http://www.etherboot.org/wiki/removable#creating_a_bootable_usb_key
| |
| 02:24 | You can do that on a hard disk as well ^^^

| 02:26 | <muppis> | |
| 02:27 | <w1r0x> Guys I can't setup LocalDev in LTSP can you help me pls. Ubuntu 10.10
| |
| 02:30 | <muppis> w1r0x, updated your ssh-keys?
| |
| 02:30 | <w1r0x> noo
| |
| 02:31 | <muppis> Try that first.
| |
| 02:31 | <w1r0x> Problem not in keys
| |
| 02:31 | problem in ltspfsmounter
| |
| 02:32 | I used DebugLocalDev guide on ubuntu wiki, & get Authentication failed. on fourth step
| |
| 02:32 | It happens while trying manualy 'ssh -X -S /var/run/ldm_socket_1851_192.168.16.37 192.168.16.37 "/usr/sbin/ltspfsmounter /tmp add"' from client
| |
| 02:33 | when i use ssh -X -S /var/run/ldm_socket_1851_192.168.16.37 192.168.16.37 gnome-terminal it works fine
| |
| 02:38 | any idea?
| |
| 02:39 | <muppis> Try run ltspfsmounter in local terminal, not over ssh.
| |
| 02:40 | <w1r0x> not over ssh it gives me Connection Error or smth like that
| |
| 02:41 | I tryed to understand the source code & purpose of error.. but I don't know python
| |
| 02:41 | rickogden has joined #ltsp | |
| 02:41 | <w1r0x> ltspfsmounter not over ssh gives "ERROR connecting"

| 02:54 | <muppis> w1r0x, there some enviromental variables missing while not running it over ssh. I think ltspfsmounter is looking for SSH_CONNECTION.

| 03:57 | <frederickjh> Can anyone here explain how audio for the ltsp clients works?
| |
| 03:57 | I am looking to set up a Radio Automation program called Rivendell with LTSP.
| |
| 03:58 | It only can use ALSA, jackd , or audio science audio sub systems.
| |
| 03:58 | <johnny> you can bridge alsa and pulseaudio
| |
| 03:58 | <frederickjh> My understanding is that LTSP is using pulseaudio
| |
| 03:58 | <Hyperbyte> Oh hey Frederick!
| |
| 03:58 | You use Rivendell? =D
| |
| 03:59 | <johnny> but ubuntu links alsa to pulse, so it shouldn't even be noticable.. unless you're running it locally
| |
| 03:59 | <Hyperbyte> I'd be very happy to hear your experiencies... pro's, con's.
| |
| 03:59 | <frederickjh> I know that johnny but I end up with gliches and drop out.
| |
| 03:59 | So is the transport to the client Alsa?
| |
| 04:00 | Do you use Rivendell Hyperbyte?
| |
| 04:00 | <Hyperbyte> Currently we're using BSI Simian for radio automation
| |
| 04:00 | Looking for something new... Rivendell is a strong candidate.
| |
| 04:01 | <frederickjh> Is it working ok for you?
| |
| 04:01 | I guess not.
| |
| 04:02 | Join us over at #rivendell if you have any questions.
| |
| 04:02 | <Hyperbyte> Oh hey cool... I will, sometime. :)
| |
| 04:02 | First I need to get Christmas behind me. =)
| |
| 04:03 | <frederickjh> OK, it is not a high traffic channel if you want to just hang to see what is going on.
| |
| 04:03 | johnny, what do you mean links alsa to pulse?
| |
| 04:04 | I want to understand how audio is handled in ltsp.
| |
| 04:04 | <johnny> on a normal ubuntu install, if you look in the alsa config, it points right to the pulse device
| |
| 04:04 | <frederickjh> So i can make this work.
| |
| 04:04 | <johnny> it's the same as on the desktop mostly, except it connects remotely
| |
| 04:04 | unless the overriden pulse init doesn't create the proper alsa device.. but that only matters if you're trying to run it locally
| |
| 04:04 | are you trying to run it normally in a thin client?
| |
| 04:05 | <frederickjh> Ok, so to use also just set pulse audio to not autospawn and change the /etc/asound.conf. Correct?
| |
| 04:05 | <johnny> then you won't get sound
| |
| 04:05 | <frederickjh> s/alsa/also
| |
| 04:05 | <johnny> pulse is mostly required on ubuntu.. just tell your app to use pulse via a wrapper or something
| |
| 04:05 | <frederickjh> OK
| |
| 04:05 | sorry
| |
| 04:05 | lets back up
| |
| 04:05 | <johnny> i can't recall the name
| |
| 04:06 | but really you never answered the question about where you're trying to run it
| |
| 04:06 | are you trying to run it locally on the client hardware? or as normal thin client app?
| |
| 04:06 | <frederickjh> Pulseaudio does not play well with Rivendell.
| |
| 04:06 | <johnny> ....
| |
| 04:06 | <frederickjh> so when we set it up normally on a Ubuntu machine we turn of the autospawning.
| |
| 04:06 | <johnny> ANSWER
| |
| 04:06 | <frederickjh> so that pulseaudio no longer runs.
| |
| 04:06 | Both.
| |
| 04:07 | <johnny> what do you mean?
| |
| 04:07 | <frederickjh> Rivendell can be networked.
| |
| 04:07 | <johnny> oh
| |
| 04:07 | ah.. too much effort for me to figure out
| |
| 04:07 | <frederickjh> You have a server with a audiostore and mysql database.
| |
| 04:07 | <johnny> if somebody doesn't answer here, you're going to have to talk to them
| |
| 04:07 | might want to ask on
| |
| 04:07 | !ltsp-discuss
| |
| 04:07 | <ltspbot> johnny: "ltsp-discuss" :: at https://lists.sourceforge.net/lists/listinfo/ltsp-discuss
| |
| 04:07 | <frederickjh> Each client uses these and runs their own daemons and setup for sound.
| |
| 04:08 | <johnny> well, if you don't plan on using any othe apps
| |
| 04:08 | then you can disable sound
| |
| 04:08 | and run your script
| |
| 04:08 | <frederickjh> So do you know if I disable pulseaudio then is alsa hiding underneath?
| |
| 04:08 | That I can use on the clients as well?
| |
| 04:09 | <johnny> just try it
| |
| 04:09 | <frederickjh> ok
| |
| 04:09 | <johnny> the lts.conf to disable sound
| |
| 04:09 | anyways.. i blame rivendell
| |
| 04:09 | or your drivers
| |
| 04:09 | <frederickjh> Yes but what
| |
| 04:09 | <johnny> so i do'nt really want to support that
| |
| 04:09 | !man lts.conf
| |
| 04:09 | <ltspbot> johnny: Error: "man" is not a valid command.
| |
| 04:09 | <johnny> !lts.conf
| |
| 04:09 | <ltspbot> johnny: "lts.conf" :: http://manpages.ubuntu.com/lts.conf
| |
| 04:10 | <frederickjh> pulse audio is an ok consumer audio sound system but for pro-audio it is lacking.
| |
| 04:10 | Blame rivendell for what?
| |
| 04:13 | <Hyperbyte> Why is pulseaudio lacking for professional use?
| |
| 04:14 | <johnny> frederickjh, well then you should be using jack .. and jack and pulse can play together
| |
| 04:14 | <frederickjh> Try it. You will find that it drops out distorts, etc.
| |
| 04:22 | Gremble has joined #ltsp | |
| 04:46 | Gremble has quit IRC | |
| 05:07 | <frederickjh> Well it will take a lot of work to figure it out. It looks like pulse audio is the transport not alsa as disabling pulseaudio on the client does not allow alsa apps to play sound.

| 07:18 | <m4xx> does the thin client manager need to be configured to work in ubuntu?
| |
| 07:19 | <frederickjh> I think you need to install some software on the clients.
| |
| 07:19 | But do not remember what.
| |
| 07:20 | I use the iTalc master interface myself.
| |
| 07:20 | <gnunux> you need x11vnc on client
| |
| 07:20 | <alkisg> Does tcm still work? Wasn't it unmaintained for a few years?
| |
| 07:20 | <gnunux> tcm has a lot of bugs ...
| |
| 07:21 | <alkisg> I thought it doesn't even start nowadays
| |
| 07:21 | <m4xx> it semi worked on edubuntu 10.10
| |
| 07:22 | doesn't seem to work at all on 10.04 server
| |
| 07:22 | i'm guessing i need to chroot to my ltsp/i386 dir and install the italc-client gnunux?
| |
| 07:22 | <alkisg> Most people use italc now, afaik
| |
| 07:22 | No, just apt-get install italc-master on the server
| |
| 07:22 | No need to touch the chroot
| |
| 07:22 | Logoff & ready
| |
| 07:22 | <gnunux> m4xx: italk != tcm
| |
| 07:23 | <frederickjh> Is it a problem if the same linux user logs on on more that one client?
| |
| 07:24 | Will I run into conflicts?
| |
| 07:24 | <alkisg> That's *always* a problem on gnome :)
| |
| 07:25 | <frederickjh> So that is a problem with the desktop manager?
| |
| 07:25 | Or if an app only allows one instance.
| |
| 07:25 | <alkisg> E.g. firefox
| |
| 07:25 | <frederickjh> ok
| |
| 07:26 | thanks.
| |
| 07:26 | robehend1 has joined #ltsp | |
| 07:32 | <robehend1> anyone know of an easy way to add an icon to all user's desktops? Beyond Sabayon, that is, as it still gives me problems.
| |
| 07:34 | <alkisg> cp? :)
| |
| 07:34 | <robehend1> I'm getting to that point ;)
| |
| 07:34 | <alkisg> You can put an xsession script that cp's it
| |
| 07:34 | E.g. in /etc/xdg/autostart/copy-desktops.desktop
| |
| 07:34 | <robehend1> will it cp it every login?
| |
| 07:35 | <alkisg> It'll do whatever you want it to, since it's a script
| |
| 07:35 | E.g. "copy if I'm in group X and the file doesn't already exist"
| |
| 07:35 | <frederickjh> I think I did that once by running the main menu editor with sudo.
| |
| 07:35 | m4xx has quit IRC | |
| 07:36 | <alkisg> Menus are easier, they're handled with gconf
| |
| 07:36 | errr .desktop files
| |
| 07:37 | <frederickjh> Sorry, wrong thing.
| |
| 07:37 | <robehend1> I've been wondering about that. If I say, log into my server with a local sudoer account, setup my Gconf so people cant screw with panels or get into command prompt, will it apply to everyone?
| |
| 07:38 | <alkisg> Sure, that's what "gconf-editor" in mandatory mode is for
| |
| 07:38 | Right click on a key -> set as mandatory etc
| |
| 07:39 | <robehend1> will it apply to current users retroactively?
| |
| 07:40 | <alkisg> Yes
| |
| 07:40 | <robehend1> hmm...
| |
| 07:41 | does Gconf tie into the Menu editor, so I can build my own menus and apply them to all users?
| |
| 07:41 | as well as allowing me to configure what modules on the panels are active and were they are placed?
| |
| 07:42 | <alkisg> Panels are difficult, in general. Their list structure doesn't allow for easy locking
| |
| 07:43 | You can lock all of them, but it's difficult to only lock a few of the objects in the panels
| |
| 07:43 | <robehend1> thats what i thought. Is there an easier desktop enviroment to configure like this? I'm by no means tied to gnome.
| |
| 07:43 | <alkisg> No idea
| |
| 07:43 | <robehend1> me either ;)

| 07:46 | <robehend1> does KDE4 perform well over LTSP, or is it simply to flashy.
| |
| 07:49 | <frederickjh> Anyone know why LDM_LOGIN_TIMEOUT= in lts.conf does not work without LDM_AUTOLOGIN=true when http://manpages.ubuntu.com/lts.conf says: " LDM_LOGIN_TIMEOUT <snip> If you specify this option, then do not specify LDM_AUTOLOGIN."?
| |
| 07:50 | It says auto login in x seconds, then counts down and does not log in with only the LDM_LOGIN_TIMEOUT= line in lts.conf
| |
| 07:52 | <robehend1> hmm, that's odd. You'd think they'd work independantly of eachother.
| |
| 07:53 | <frederickjh> Yes, you would.
| |
| 08:06 | <robehend1> alkisg: Is there a way to set Gconf keys mandatory for a group, instead of all users? Say, my likewise-open users, but not my local? Don't want to accidently lockout my admin account
| |
| 08:08 | mistik1 has quit IRC | |
| 08:11 | Gadi has joined #ltsp | |
| 08:11 | <frederickjh> Sorry the countdown does not happen with both so, LDM_LOGIN_TIMEOUT= just does not work.
| |
| 08:13 | Same LDM_USERNAME and LDM_PASSWORD lines just change the LDM_LOGIN_TIMEOUT line to a LDM_AUTOLOGIN and it works.
| |
| 08:14 | I must be missing a needed parameter for LDM_LOGIN_TIMEOUT. It counts down the seconds but then never does its thing.
| |

| 08:15 | <Gadi> morning, all
| |
| 08:15 | <robehend1> mornin
| |
| 08:15 | <mgariepy> good morning
| |
| 08:15 | <stgraber> morning Gadi
| |
| 08:16 | <Gadi> frederickjh: just read the last 3 lines, but are you looking for LDM_GUESTLOGIN?
| |
| 08:16 | <frederickjh> nope
| |
| 08:16 | <Gadi> ok, then
| |
| 08:16 | carry on
| |
| 08:16 | :)
| |
| 08:16 | <frederickjh> I am looking to get LDM_LOGIN_TIMEOUT=7 working.
| |
| 08:16 | * Gadi thought that only works in conjunction with LDM_GUESTLOGIN | |
| 08:17 | <Gadi> but, I could be wrong
| |
| 08:17 | <frederickjh> I want it to auto login a user after 7 seconds
| |
| 08:17 | <Gadi> especially first thing in the morning
| |
| 08:17 | <frederickjh> Ok let me take another look.
| |
| 08:17 | stgraber has quit IRC | |
| 08:18 | <frederickjh> I don't see that in the man page Gadi
| |
| 08:18 | stgraber has joined #ltsp | |
| 08:18 | <Gadi> frederickjh: let's take a peak at the code...
| |
| 08:18 | <frederickjh> ok
| |
| 08:21 | Another question, What is the expected result of adding the line "SOUND=N" to a client in lts.conf?
| |
| 08:21 | I understand no sound on the client, but ...
| |
| 08:21 | <Gadi> frederickjh: pulseaudio will not start
| |
| 08:21 | <robehend1> yep, and without pulse, you've got nothin
| |
| 08:21 | <Gadi> well, not completely true
| |
| 08:21 | <frederickjh> what I did not expect is that the sound manager will run and use the pulseaudio on the server.
| |
| 08:22 | <Gadi> local apps may still produce sound through alsa
| |
| 08:22 | <frederickjh> Sound then comes from the server.
| |
| 08:22 | <Gadi> ah
| |
| 08:22 | yeah, well
| |
| 08:22 | <robehend1> i was unaware that local apps would do that..I'll have to take a look at that..
| |
| 08:22 | <Gadi> that will happen as the client will no longer say, use my sound
| |
| 08:22 | <frederickjh> The adjustment of an applications sound in the sound manager can be done on both the client and server.
| |
| 08:22 | ok
| |
| 08:22 | So that is the expected result.
| |
| 08:23 | Not no sound anywhere from the client.
| |
| 08:24 | I would hate to be in a computer lab disable sound on the clients and then be bombarded by all the sound they are trying to play in the server room.
| |
| 08:24 | <robehend1> disable the soundcard on the server?
| |
| 08:24 | <frederickjh> Yes
| |
| 08:25 | I just got laugh at thinking about the newbie ltsp sysadmin that thinks they can knock the sound level down that way.
| |
| 08:25 | <robehend1> i've given students sound, myself. And told them if they screw up with it, we simply take it away
| |
| 08:27 | They've learned really fast.
| |
| 08:28 | <frederickjh> However I am looking at this from another stand point. That of using a linux radio automation system on ltsp.
| |
| 08:29 | <robehend1> oo, explain. I'm confused on what you mean
| |
| 08:29 | <frederickjh> So I am just trying to figure out how it works and how it could work in that situation.
| |
| 08:29 | do you mean with the linux radio automation system, robehend1?
| |
| 08:30 | <robehend1> frederickjh: Mhmm
| |
| 08:30 | <frederickjh> Rivendell is a linux radio automation system.
| |
| 08:30 | You can network it.
| |
| 08:30 | The client share a common mysql database and audio store.
| |
| 08:31 | <robehend1> oh, i see what your talking about now.
| |
| 08:31 | <frederickjh> and playout the audio locally via a central audio engine daemon.
| |
| 08:31 | The question is how to set this up on top of ltsp.
| |
| 08:31 | and have all the sound come out of the server.
| |
| 08:32 | Except for maybe cuing audio.
| |
| 08:33 | <robehend1> No clue here. I'd have to look more into the program to have any form of an idea
| |
| 08:33 | _UsUrPeR__ is now known as _UsUrPeR_ | |
| 08:34 | <frederickjh> I have a good idea already.
| |
| 08:35 | <robehend1> Gadi: You might know. Since Sabayon still hasnt been working right for either of us without tweaks everywhere, I've been looking for an easier to use desktop setup for my students. Easier to use on my end, lockdown and configuring. Any suggestions, or is it really best to stick with Gnome
| |
| 08:35 | oh?
| |
| 08:35 | <frederickjh> Rivendell and Jackd on the clients. Netjack to jack on the server or multiple sound cards on the server on for each client via alsa.
| |
| 08:35 | <robehend1> I hope your not running too many clients then..a card each would take up so much space..
| |
| 08:36 | <frederickjh> I think you would run out of CPU as well with too many.
| |
| 08:36 | <robehend1> depending on the cpu, ya. eventually
| |
| 08:36 | though I've found LTSP to manage CPU utiliization quite well
| |
| 08:36 | <frederickjh> The idea is to be able to setup a 2- 4 studio setup.
| |
| 08:37 | How many will depend on the hardware.
| |
| 08:37 | alkisg has quit IRC | |
| 08:52 | <frederickjh> Anyone know where you would setup fstab entries for mounting a nfs share on the clients? /opt/ltsp/i386/etc/fstab says: "# UNCONFIGURED FSTAB FOR BASE SYSTEM"
| |
| 08:52 | <robehend1> frederickjh: I've went to use libpam_mount for that, instead of Fstab
| |
| 08:52 | <frederickjh> Or is there an easier way to mount a common folder?
| |
| 08:53 | <robehend1> that way, it logs in only for specified user groups, giving more security.
| |
| 08:53 | <frederickjh> is there a man page for that
| |
| 08:53 | man libpam_mount does not find one.
| |
| 08:54 | <robehend1> let me take a look. if not, i know theres internet docs
| |
| 08:54 | off the sourceforge page: http://pam-mount.sourceforge.net/doc.php
| |
| 08:55 | i use it in conjuncture with likewise-open, so ymmv
| |
| 08:55 | <frederickjh> ok
| |
| 08:56 | Ok, That sound great. So I can have it mount a folder only if the user belongs to a specific group, corrrect?
| |
| 08:58 | Is likewise-open another program?

| |
| 11:00 | <_UsUrPeR_> alkisg: copy-sourceslist?
| |
| 11:00 | <Rastus> Does changing the location in sources make a difference?
| |
| 11:02 | <_UsUrPeR_> alkisg: I thought the build always used the same source unless you told it specifically not to...
| |
| 11:02 | <alkisg> Rastus: hmm yes you could try adding --copy-sourceslist to ltsp-build-client like _UsUrPeR_ suggested
| |
| 11:02 | But yup I thought so too
| |
| 11:02 | <_UsUrPeR_> Rastus: try ltsp-build-client --copy-sourceslist
| |
| 11:02 | <alkisg> Rastus: can you pastebin your /opt/ltsp/i386/etc/sources.list?
| |
| 11:02 | <_UsUrPeR_> Rastus: also, are you running a 64-bit server?
| |
| 11:02 | <Rastus> OK - newbie to IRC here. pastebin?
| |
| 11:02 | <_UsUrPeR_> if so, you may want to add --arch i386 in there as well

| |

| 11:23 | m4xx has joined #ltsp | |

| |
| 11:25 | <Rastus> Yes it is
| |
| 11:25 | I ran sudo ltsp-build-client --copy-sourceslist
| |

| 11:30 | m4xx: which graphics card and what monitor, tftp or old crt?
| |

| 11:30 | <m4xx> i have two different monitors

| |
| 11:35 | <alkisg> Rastus: Maybe it's got something to do with xubuntu, I haven't seen that with ubuntu/edubuntu
| |
| 11:35 | <m4xx> that's the unit
| |
| 11:36 | <alkisg> m4xx: hmmm strange that gma950 doesn't read your monitor edid. Did lspci confirm that it is indeed gmd950?
| |
| 11:36 | <m4xx> lspci wasn't found =\
| |
| 11:36 | ack lcpci
| |
| 11:36 | is it lspci?
| |
| 11:37 | <alkisg> (07:35:39 PM) alkisg: m4xx: lspci, sorry
| |
| 11:37 | <m4xx> oops
| |
| 11:37 | i'm blind ;[
| |
| 11:38 | <alkisg> Rastus: I think now to troubleshoot the problem you'd need to chroot, run `apt-get install -f`, and see why initramfs-tools fails. But that's too technical.
| |
| 11:38 | Maybe try with ubuntu or edubuntu instead?
| |
| 11:39 | Want me to have a look with vnc?
| |
| 11:39 | <Rastus> I'm willing
| |
| 11:39 | Step me through it
| |

| |
| 11:39 | That's all...
| |
| 11:40 | <Rastus> You're a generous individual
| |
| 11:40 | <alkisg> I'm used to providing support to teachers with vnc here... so it's routine now :)

| |
| 11:50 | <alkisg> m4xx: I see... weird for intel. You can tell the driver to use a higher resolution by using X_HORZSYNC and X_VERTREFRESH.
| |
| 11:50 | Open lts.conf and put:
| |
| 11:51 | [Default]
| |
| 11:51 | X_HORZSYNC=30-88
| |
| 11:51 | X_VERTREFRESH=30-88

| |
| 11:51 | If that gives you 1024x768, try to find the correct timings for your monitors.

| 11:52 | <robehend1> I've had bad luck with GMA950 before. Sometimes it works great, but mostly, I either get no display or small display. Haven't found a fix yet.
| |
| 11:52 | wasn't exactly sure where to put a bug report, as i've had it happen in standalone *buntu installations too
| |
| 11:53 | <m4xx> the gentalman that i had talked to on the phone said it would work great >=\
| |
| 11:54 | i'm using the same monitors that worked on my fat client
| |
| 11:54 | so i already know the resolutions i want
| |
| 11:54 | should i boot up the old one and see what the refresh rates were?
| |
| 11:55 | <robehend1> if the crt is made in the last 9 years, i'd bet its 60hz. I havent ran into a non-60 crt in forever
| |
| 11:56 | <alkisg> m4xx: first, try what I wrote above, to verify that this is indeed your problem
| |
| 11:57 | Put X_VERTREFRESH=30-70 if you prefer
| |
| 12:00 | (how do you connect your monitors? dsub, dvi, hdmi?)
| |
| 12:02 | gorkhaan has joined #ltsp | |
| 12:03 | <alkisg> Rastus: you're having problems downloading the packages, probably that's why it fails...
| |
| 12:03 | <Rastus> Why would that be?
| |
| 12:03 | Router?
| |
| 12:03 | <m4xx> one is vga, the other is dvi->vga
| |
| 12:03 | <alkisg> Rastus: no idea
| |
| 12:03 | <Rastus> Fair enough
| |
| 12:04 | <alkisg> Rastus: Let's see if it succeeds once it downloads all the packages
| |
| 12:04 | <Rastus> Funnily enough it works just fine in Xubuntu 9.04. I've done it several time
| |
| 12:08 | <alkisg> Rastus: it might be some bug in xubuntu 10.10 then. Maybe apt-related, as vnc works fine...
| |
| 12:08 | <Rastus> Obviously... :)
| |
| 12:08 | I haven't been able to get it to work for 9.10 all the way ip
| |
| 12:09 | * alkisg prefers LTS releases, they're more stable | |
| 12:17 | <Gadi> m4xx: log into ldm with the low resolution, open a terminal, and type "xrandr"
| |
| 12:23 | <Rastus> clever
| |
| 12:24 | <m4xx> i've contacted the place i got it from and they sent me a script
| |
| 12:25 | he said it's because it's using lvds and that's causing the problem
| |
| 12:26 | the script seems to have fixxed the resoluion issue but for some reason it doesn't allow me to have a desktop that extends both monitors when using a dvi to vga converter =[
| |
| 12:32 | <_UsUrPeR_> hey all. can someone take a look at this auth log? http://pastebin.com/fVnqJjSm
| |
| 12:32 | I can't figure out why some clients are able to log on, while others are not
| |
| 12:33 | this specific login attempt is with LDM, and it just resets back to LDM when it fails
| |
| 12:33 | <alkisg> Maybe X crashed?
| |
| 12:33 | <m4xx> maybe regenerate ssh keys?
| |
| 12:34 | <alkisg> !compiz
| |
| 12:34 | <ltspbot> alkisg: "compiz" :: the default window manager in gnome is gnome-wm, which automatically chooses compiz if it thinks that the card supports it. Compiz is causing login problems to some clients (LP #673072). To disable it, see !disable_compiz. To restore it, see !restore_compiz
| |
| 12:34 | <alkisg> Some users may have disabled compiz in the appearance settings
| |
| 12:34 | <m4xx> !disable_compiz
| |
| 12:34 | <ltspbot> m4xx: "disable_compiz" :: To disable compiz, try: sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type string --set /desktop/gnome/session/required_components/windowmanager metacity
| |
| 12:34 | <alkisg> So thats _one_ reason why some users are able to "login" while others not
| |
| 12:34 | *might be...
| |
| 12:40 | <robehend1> alkisg: say, do you run that script on the server, or on a client through a local xterm
| |
| 12:40 | <alkisg> robehend1: what script? the command to disable compiz?
| |
| 12:40 | <robehend1> alkisg: mhm
| |
| 12:40 | <alkisg> On the server, it works for all users.
| |
| 12:41 | <robehend1> nice...i should do that, less resources used, they dont need pretty anyways
| |
| 12:41 | <alkisg> I heard that compiz provides smoother scrolling / moving of windows etc on good clients that support it
| |
| 12:41 | Didn't have a good client so far to test it with :)
| |
| 12:42 | <robehend1> same here ;)
| |
| 12:42 | though one thing I am getting alot of, and I'm not sure why, is a hang at login
| |
| 12:42 | LDM loads up fine, logins go in fine, but I get a good 30 sec hang until I have a workable session and/or all libpam mounts
| |
| 12:42 | <alkisg> dns?
| |
| 12:43 | <robehend1> nope, local dns is workign fine. I've got the servers put right into the host file
| |
| 12:43 | <alkisg> I've seen long timeouts when reverse dns fails
| |
| 12:43 | (the server some times needs to lookup the clients, ltsp151 etc)
| |
| 12:43 | <robehend1> and nsswitch.conf is pointing to file dns, etc
| |
| 12:43 | hmm.
| |
| 12:44 | <alkisg> Rastus: watch for any errors *except* for those about debconf passthrough
| |
| 12:44 | <Rastus> I'm on it
| |
| 12:45 | <alkisg> It looks like it's going to work this time :D
| |
| 12:45 | <Rastus> It'd be nice....
| |
| 12:46 | <alkisg> Those things run in your chroot now, and it seems that this is not affected by your downloading problem
| |
| 12:46 | <Rastus> a short list of what you did so that I could repeat it would be great
| |
| 12:46 | <Gadi> m4xx: again, type: xrandr in a terminal
| |
| 12:46 | <alkisg> Rastus: I wonder if it's an apt setting in your server
| |
| 12:46 | <m4xx> sorry
| |
| 12:46 | ok
| |
| 12:46 | <alkisg> Rastus: mainly, I downloaded all the packages with aptitude download and put them in /var/cache/apt/archives so that ltsp-build-client --mount-package-cache would find them there
| |
| 12:47 | <Rastus> OK
| |
| 12:47 | <Gadi> chances are the converter is not allowing that output to get modes from the monitor
| |
| 12:47 | <Rastus> I was following along and that was what I saw, but I was wondering if the earlier things you did made any difference
| |
| 12:47 | <alkisg> Nope, those were just tries until I pinpointed the problem
| |
| 12:48 | <Rastus> Good. I haven't totally lost it then :)
| |
| 12:48 | Rastus has quit IRC | |

| |
| 12:52 | <Gadi> m4xx: DVI1 disconnected
| |
| 12:52 | <alkisg> Rastus: is the installation continuing?
| |
| 12:52 | <Rastus> alkisg: My monitor just went to standby and came back to a login screen
| |
| 12:52 | <m4xx> is there anything i can do to get it to detect?
| |
| 12:52 | <Gadi> m4xx: sure
| |
| 12:52 | <m4xx> aside from using an actual dvi connection
| |
| 12:52 | <alkisg> Rastus: urm. Never heard of x11vnc causing that one. Maybe totally unrelated...
| |
| 12:52 | <Gadi> m4xx: right now, that monitor displays nothing, right?
| |
| 12:53 | <m4xx> no, it displays a mirror
| |
| 12:53 | <Rastus> Didn't do a full reboot. It was as if the login session just died
| |
| 12:53 | <alkisg> Rastus: I'd reboot and run ltsp-build-client --mount-package-cache from scratch
| |
| 12:53 | Rastus: also check your ~/.xsession-errors
| |
| 12:53 | <m4xx> would you like me to pastebin the script they gave me so you can see the full picture?
| |
| 12:53 | <Gadi> m4xx: at the terminal, type: xrandr --output DVI1 --auto
| |
| 12:53 | <m4xx> ok
| |
| 12:54 | <Rastus> Thanks SO MUCH for all your time and help alkis. It is above and beyond the call of duty. I wish you well
| |

| |
| 12:55 | <m4xx> doesn't seem to have had any effect
| |
| 12:55 | <Gadi> m4xx: and, you say that the screen resolution dialog doesn't give you much, right?
| |
| 12:56 | m4xx: what resolutions are you after?
| |
| 12:56 | <m4xx> the script they gave me fixxed my resolution issue
| |
| 12:56 | <Gadi> ok, let's see the script
| |
| 12:56 | <m4xx> OK

| 13:01 | m4xx: if I were you, for dualhead, I would set specific entries in your lts.conf, so for example, for 1280x1024 on both displays, do something like:
| |
| 13:01 | [<MAC>]
| |
| 13:02 | X_VIRTUAL="2560 2560"
| |
| 13:02 | <m4xx> i tried that before the hack and it didnt work
| |
| 13:02 | <Gadi> XRANDR_OUTPUT_0 = "VGA1"
| |
| 13:02 | <m4xx> he said because it uses the ldvs
| |
| 13:02 | <Gadi> XRANDR_MODE_0 = 1280x1024
| |
| 13:02 | XRANDR_OUTPUT_1 = "DVI1"
| |
| 13:03 | <m4xx> DVI1 did not exist befor the hack
| |
| 13:03 | it showed up as LDVS1
| |
| 13:03 | <Gadi> (or XRANDR_OUTPUT_1 = "DVI1 --left-of VGA1")
| |
| 13:03 | XRANDR_MODE_1 = 1280x1024
| |
| 13:04 | <m4xx> and that this client is detected as a netbook or something similar so it thinks there is a built in monitor
| |
| 13:04 | <Gadi> m4xx: right, so now that you have xrandr displaying the right outputs, go ahead and set them properly
| |
| 13:04 | <m4xx> OK will do
| |
| 13:05 | <Gadi> The only twist you have here is your DVI->VGA converter which makes the DVI look disconnected
| |
| 13:06 | <m4xx> updated image, rebooting now
| |
| 13:06 | <Gadi> you dont need to update the image
| |
| 13:06 | only the lts.conf
| |
| 13:06 | it gets tftp'd
| |
| 13:06 | on boot
| |
| 13:07 | * Gadi aassumes u are editing /var/lib/tftpboot/ltsp/i286/lts.conf | |
| 13:07 | <Gadi> er, i386
| |

| |

| 13:08 | oops
| |
| 13:08 | no i was editing /opt/ltsp/i386 ...
| |
| 13:08 | Trixboxer has quit IRC | |
| 13:09 | <Gadi> rookie mistake, happens to everyone
| |
| 13:09 | :)
| |
| 13:09 | <robehend1> i wanna see a 286 running LTSP now, Gadi
| |
| 13:09 | <m4xx> lol
| |
| 13:09 | Gadi: no effect :( still mirrored
| |
| 13:10 | <Gadi> yo mama's thin client's so fat, when she sees a 286 running LTSP, she changes the channel
| |
| 13:10 | m4xx: type xrandr in a terminal again
| |
| 13:10 | let's see what it tells us
| |
| 13:10 | <m4xx> same as last
| |
| 13:11 | <Gadi> run: ltsp-localapps xterm
| |
| 13:11 | <m4xx> yes
| |
| 13:11 | that's what i did
| |
| 13:11 | output is the same =[
| |
| 13:11 | <Gadi> and in the xterm, type: cp /var/log/Xorg.7.log ~/
| |
| 13:11 | cliebow has joined #ltsp | |
| 13:11 | <Gadi> then paste the Xorg log file to pastebin from ur homedir
| |
| 13:12 | ooh
| |
| 13:13 | nm
| |
| 13:13 | yes, paste it
| |
| 13:14 | <m4xx> http://pastebin.us/1795
| |
| 13:17 | <Gadi> and can you also:
| |
| 13:17 | (in the xterm)
| |
| 13:17 | cp /var/run/ltsp-xorg.conf ~/
| |
| 13:17 | and paste that
| |
| 13:17 | <m4xx> sure
| |
| 13:18 | http://pastebin.us/1796
| |
| 13:20 | <Gadi> aha!
| |
| 13:20 | his little patch backfired on ya!
| |
| 13:22 | <m4xx> any ideas?
| |
| 13:23 | * _UsUrPeR_ re-reads above | |
| 13:23 | <_UsUrPeR_> ok
| |
| 13:23 | m4xx: sorry if I missed this, but what client are you using?
| |
| 13:24 | <m4xx> ltsp 1720
| |
| 13:24 | <_UsUrPeR_> and what's going on?
| |
| 13:24 | having problems with resolutions?
| |
| 13:24 | <m4xx> trying to use dual monitors one vga, one dvi to vga
| |
| 13:24 | <_UsUrPeR_> did I just speak to you on the phone? :)
| |
| 13:25 | <m4xx> perhaps =]
| |
| 13:25 | <_UsUrPeR_> (it's joel from DLW)
| |
| 13:25 | <m4xx> yes sir
| |
| 13:25 | i believe so :)
| |
| 13:25 | <robehend1> i've been meaning to call DLW..time to get some price checks ;)
| |
| 13:26 | <m4xx> once i get this small glitch fixxed i will be extremely happy :)
| |
| 13:26 | <robehend1> we're looking at a school wide deployment, as soon as I figure out how I would use the windows-only testing software on LTSP..

| 13:27 | <_UsUrPeR_> hmm
| |
| 13:28 | <Gadi> m4xx: try removing the hack, rerolling the image, and use this in lts.conf: http://pastebin.us/1797
| |
| 13:28 | (remove hack with: sudo rm /opt/ltsp/i386/usr/share/ltsp/screen-session.d/XS20-xserver-intel-desktop-hack)
| |
| 13:31 | <_UsUrPeR_> gadi: can we somehow get that script (or just the model number) integrated in to an ltsp release?
| |
| 13:31 | having to send that script out to people is making me sad :)
| |
| 13:31 | <Gadi> sure
| |
| 13:31 | <_UsUrPeR_> that would be awesome
| |
| 13:32 | <robehend1> so, anyone seen this new Userful Multiseat 2011 thats in beta now?
| |
| 13:32 | <Gadi> but, if it doesn't let dual monitors work, maybe you want a better hack
| |
| 13:32 | :)
| |
| 13:32 | <_UsUrPeR_> Gadi: regardless, LVDS needs to be disabled on this chipset, or the box is nigh-useless
| |
| 13:33 | and it does with (and quite well I might add) when an actual DVI monitor is plugged in, and capable of being detected by the client
| |
| 13:35 | <Gadi> bbiab
| |
| 13:35 | meeting
| |
| 13:38 | <cliebow> blah..blahblah
| |
| 13:41 | <_UsUrPeR_> cliebow: have you watched "Arrested Development"?
| |
| 13:41 | there's a character played by the guy from "Charles in Charge" named "Bob Loblaw". He was an attorney
| |
| 13:42 | <alkisg> robehend1: nice video, it mostly applies to LTSP as well :)
| |
| 13:42 | (the userful video)
| |
| 13:43 | <cliebow> _UsUrPeR_, sorry..i am out of the loop movie-wise..but i will try to netflick it for the hell of it tonight.
| |
| 13:44 | <_UsUrPeR_> this was a TV show from 2005. no big deal. It's a cult following
| |
| 13:44 | <cliebow> i see..i knid of lost touch with tv when i built the new house...and had no reception
| |
| 13:46 | <_UsUrPeR_> :)

| |
| 13:47 | <Rastus_TS_Client> Ahhh - you picked up on that did you?
| |
| 13:47 | :D
| |
| 13:47 | <alkisg> ;)
| |
| 13:47 | <Rastus_TS_Client> Very, very happy little camper over here.
| |
| 13:47 | Thanks SO much for your help.
| |
| 13:47 | <alkisg> np - you still need to find out what the download problem is, though
| |
| 13:47 | <robehend1> alkisg: i thought that as soon as I saw it. I think the secret is there 'fancy' usb thin client
| |
| 13:48 | <Rastus_TS_Client> Logged in just to tell everyone that you are brilliant and I appreciate the effort.
| |
| 13:48 | <alkisg> robehend1: I think that's multiseat, not thin clients, i.e. no local network involved
| |
| 13:48 | <Rastus_TS_Client> Yes - that download issue is a puzzler.
| |
| 13:49 | <robehend1> alkisg: True. i wonder what their pricing is, just for curiosity's sake. and I hope they put a gig nic in that host machine, as it's network will tremble at 10 kids on Flash games
| |
| 13:49 | <Rastus_TS_Client> I'll take your suggestion and change DNS servers and see if that makes a difference
| |
| 13:49 | <alkisg> robehend1: For n-computing, the windows version, I read that it only supports about 15 mbps of video, and no 3d apps, so ltsp is better as it can easily send 100mbps of video to each client
| |
| 13:49 | <robehend1> alkisg: I have N-computing here in my district, so I can state openly that it is a horrendous peice of hardware/software
| |
| 13:50 | <alkisg> robehend1: ah, some teachers here were interested on that, can you give me a few comments? just 2-3 lines to tell them... :)
| |
| 13:51 | <robehend1> alkisg: Well, if they use Flash/shockwave based systems, be prepared for loading, loading, loading. Boot times number in minutes, not seconds. Also, Windows updates are a no-no, as every 3 months like clockwork a win. update breaks V-space, the key to N-computing
| |
| 13:51 | alkisg: Oh. And randomly the cards will fail, dropping 5 workstations.
| |
| 13:51 | <alkisg> Heh. Very very nice description, I think that'll be convincing :)
| |
| 13:51 | <robehend1> alkisg: I'm a beta tester for their systems, so i've worked with all the L, X, and U series, and can go more in depth privately if you prefer.
| |
| 13:52 | <Rastus_TS_Client> Good afternoon all. Thanks again Alkis.
| |
| 13:52 | <alkisg> No no that will be more than enough :)
| |
| 13:52 | Bye Rastus

| 13:54 | [GuS] has quit IRC | |
| 13:55 | <robehend1> so i had another one of my "Linux is bad and you should feel bad for making our kids use it" lectures today from a parent
| |
| 13:55 | Gosh I love them
| |
| 13:56 | <m4xx> did you ask them to kindly remove their head from their ass befor they speak to you?
| |
| 13:56 | <robehend1> it more boiled down into "Why is it bad", and their answer was " Tried Ubuntu 6.01 and it sucked!"
| |
| 13:57 | followed by the ever present "it kept asking for my password to change things, and I hated that!"
| |
| 13:57 | <m4xx> did you ask them if they've tried vista?
| |
| 13:57 | <robehend1> oh no. they want win 7
| |
| 13:57 | <muppis> robehend1, did they said when they tried it?
| |
| 13:57 | <robehend1> everywhere
| |
| 13:57 | Nope, no time frame was given, and i didnt want to start that fight.
| |
| 13:58 | then, to round out the evening, i recieved the "Our kids arent learning what they'll use in the real world! What are they going to do after high school?!"
| |
| 13:58 | <m4xx> hmm, main pannel doesn't show when logging in =\\
| |
| 14:00 | <muppis> robehend1, sounds like they trust to MS like to bedrock.
| |
| 14:01 | <robehend1> muppis: Pretty much. Funny thing is, they use Google Apps for the majority of their work..
| |
| 14:01 | <muppis> Yet another Giant..
| |
| 14:01 | <robehend1> I've got no qualms with Google. I accept they read my data, and frankly am fine with it
| |
| 14:03 | <muppis> I'm fien with that they index my search behaviour. But ads to my contacts go over. I use Gmail everyday basis, but only over IMAPS.
| |
| 14:03 | <robehend1> ah. Luckily, Google Apps for EDU allows you to strip the ads out
| |
| 14:03 | <muppis> Good.
| |
| 14:06 | I must admit. I'm now using XP's printing wizard for printing pics from my kids. Had no time to learn same tricks in Ubuntu and I cheat XP with HP's settings a little bit.
| |
| 14:06 | <robehend1> ya, its a pretty sweet deal for education. heck, for the windows machines, i replaced the Start>Programs>office>Openoffice with Start>Programs>Office>Google Docs
| |
| 14:09 | <Pweg> wow, that's really slick actually, I'd love to be able to do that for the users here that are stuck with windows.
| |
| 14:09 | Gremble has joined #ltsp | |
| 14:09 | <robehend1> oh, its pretty simple.
| |
| 14:10 | Just make a shortcut to https://docs.google.com/a/yourdomainhere.com/?action=newdoc and put it in the start menu list
| |
| 14:11 | <Pweg> I never would have thought of that, thanks :)
| |
| 14:11 | <robehend1> and it'll launch your default web browswer, ask you to login, and BOOM, new google doc
| |
| 14:11 | ha dont thank me. it's a trick i got from Lifehacker
| |
| 14:12 | <Pweg> That's awesome, haha.
| |
| 14:12 | <robehend1> and hers to hoping I can get a free CR-48 from Google to try out the Chrome OS, and then steal the ideas from there and roll into my LTSP setup
| |
| 14:12 | Gremble has quit IRC | |
| 14:13 | <Pweg> yeah, my fingers are still crossed for one, so far I think they've shipped something around 60,000
| |
| 14:13 | <robehend1> I wish they would tell you if you've been selected, but all I hear is people randomly have one dropped off
| |
| 14:13 | <Pweg> ah, guess I can stop refreshing my email compulsively then
| |
| 14:13 | <robehend1> ha, me as well
| |
| 14:14 | i'm interested in Chrome OS, sure.
| |
| 14:14 | But i'd also *love* a free hackable netbook..
| |
| 14:14 | <Pweg> ditto, hehe
| |
| 14:14 | <robehend1> espicially a sexy, non-branded, almost OEM looking one.
| |
| 14:15 | <Pweg> I was worried about how the plastic would turn out, but so far reviews have been pretty positive
| |
| 14:15 | <robehend1> google doesnt do anything cheap, these days.
| |
| 14:15 | <Pweg> true that, waiting excitedly for Google IO tickets to go up too
| |
| 14:16 | <robehend1> Google IO?
| |
| 14:16 | <cliebow> like Cool io but for Google
| |
| 14:16 | <robehend1> not familiar. is it some bookmarking service?
| |
| 14:16 | <Pweg> nah, it's basically their annual dev conference
| |
| 14:17 | <robehend1> oh...
| |
| 14:17 | i doubt i could get tickets to that put on my expense account ha
| |
| 14:17 | <Pweg> it's a 2 day conference, tickets are around $400 I think
| |
| 14:17 | <robehend1> its the travel thats no fun
| |
| 14:17 | I already had to travel for my G-apps teacher academy, so i doubt i get it again
| |
| 14:18 | <Pweg> yeah, I hear you on that, hehe
| |
| 14:20 | everybody that goes gets something for free, I think last year was a Nexus One, they just gave all their developers a new Google TV a few months ago, I think speculation is that this time it's going to be the netbook
| |
| 14:20 | <robehend1> gosh i'd love a nexus one. my Hero isnt cutting it, even with custom roms
| |
| 14:21 | <Pweg> isn't that a relatively new model too?
| |
| 14:21 | <robehend1> about a year old
| |
| 14:21 | but its not being updated past 2.1
| |
| 14:22 | <Pweg> ah, sad
| |
| 14:22 | <robehend1> thats what custom roms are for, luckily
| |
| 14:22 | <Pweg> hehe
| |
| 14:22 | hoping for a Nexus 2 then?
| |
| 14:23 | <robehend1> ha, i'm on sprint, i'm hoping for anything
| |
| 14:23 | <Pweg> haha
| |
| 14:26 | ah, lunch time has finally arrived. :) Nice chatting with you
| |
| 14:27 | <robehend1> see ya!

| 14:45 | * _UsUrPeR_ tips his hat | |
| 14:45 | <_UsUrPeR_> having some localapps sound problems
| |
| 14:46 | <robehend1> whats goin on?
| |
| 14:47 | <_UsUrPeR_> I am getting an error stating that alsa is not able to find the specified sound card, though in the shell, i am able to see the sound card with "alsamixer". Here's the output from firefox when I attempt to play a youtube video: http://pastebin.com/Uq0RQjGj
| |
| 14:47 | in my lts.conf, I have "sound=false"
| |
| 14:47 | and firefox is running as a localapp
| |
| 14:47 | <robehend1> not sure. but does sound-false disable it's detection of a sound card for pulse?
| |
| 14:48 | <_UsUrPeR_> robehend1: correct. It settles any conflict problems between ltsp and the local hardware
| |
| 14:48 | by disabling all sound output via LTSP
| |
| 14:48 | <robehend1> hmm
| |
| 14:48 | <_UsUrPeR_> now, I can guarantee sound would work if sound=false were taken out of the equation, but it would not work for localapps, which I value more than system sounds
| |
| 14:49 | <robehend1> Well, see, thats the weird part. i've got sound for LocalApps and server apps, and i've got no sound=* tags in my lts.conf
| |
| 14:49 | <_UsUrPeR_> and that would still not allow sound to play with flash if the program were being run as a localapp
| |
| 14:49 | robehend1: the real question is, are you certain your programs are being run locally? :)
| |
| 14:50 | <robehend1> _UsUrPeR_: yep, since flash is only installed in the chroot and not the server ;)
| |
| 14:50 | <_UsUrPeR_> robehend1: is firefox installed on both the server and the client?
| |
| 14:50 | <robehend1> yes.
| |
| 14:51 | <_UsUrPeR_> robehend1: to be specific, if you run (in terminal) "ltsp-localapps xterm" then run "top" in the subsequent window which appears, it shows that flash is running on the client.
| |
| 14:51 | it would be apparent by the amount of proc power being used on the client
| |
| 14:51 | <robehend1> i could hop onto a client and check, but it'd have to wait a solid 30 min for my last class to exit ;)
| |
| 14:52 | <_UsUrPeR_> typically, with the smallish procs inside clients, it would result in ~80 - 100% usage
| |
| 14:52 | <robehend1> all I know is that anytime i check Htop on the server, there are no firefox procs running at all
| |
| 14:52 | <_UsUrPeR_> robehend1: I would be intrigued to find your results
| |
| 14:52 | typically, I install firefox, flash, and java all on the same client installation
| |
| 14:53 | <robehend1> same here
| |
| 14:53 | <_UsUrPeR_> and use locap_apps_menu = true to ensure that xprop is propagated to all client users
| |
| 14:53 | gadi / alkisg: any ideas? ^^
| |
| 14:54 | <robehend1> see, i build all my menus, and make sure the ltsp-localapps tag is always in there.
| |
| 14:55 | evil_root is now known as zz_evil_root | |
| 14:58 | <alkisg> _UsUrPeR_: I'm not much of a sound expert, and I don't use localapps, but I think since lucid alsa apps and pulse apps can coexist so I don't think sound=false is needed...
| |
| 15:01 | Did disabling compiz solve your login issues?
| |
| 15:05 | <_UsUrPeR_> alkisg: yeah. again.
| |
| 15:05 | I guess a server update blew away the settings I put in there originally
| |
| 15:05 | <alkisg> ok
| |
| 15:06 | Gadi has left #ltsp | |
| 15:06 | cliebow has quit IRC | |
| 15:06 | <_UsUrPeR_> alkisg: so sound=false is no longer required in 10.04 or 10.10 or both?
| |
| 15:06 | <alkisg> I *think* both. I'm not using localapps so I can't say for sure...
| |
| 15:06 | <_UsUrPeR_> did not expect that issue to ever be resolved. That's good news
| |
| 15:07 | and another pita that doesn't have to be worked around when using ltsp for SIP devices! :D
| |
| 15:07 | <robehend1> i love using it as SIP
| |
| 15:07 | <alkisg> Well channeling sound through network does have a delay though
| |
| 15:07 | And might even have some distorsion... localapps are better for sound apps
| |
| 15:07 | <_UsUrPeR_> I agree. How is that differentiated?
| |
| 15:07 | <robehend1> not much worse than a usual voip phone
| |
| 15:08 | <_UsUrPeR_> is that just localapps or non-localapps and that's it?
| |
| 15:21 | <robehend1> I have a random, nonltsp question, but who knows, you guys might be able to help
| |
| 15:22 | That mosquito ringtone for cellphones, the one that as you get older you lose the ability to hear..any idea how to counteract students using it to text all the time in our..ahem..more mature teacher's rooms?

| |
| 15:37 | <_UsUrPeR_> not quite sure how that will fix anything, but... ya know.
| |
| 15:38 | my hs had a "no cell phone" policy
| |
| 15:38 | <robehend1> thats what i'm gonna suggest
| |
| 15:38 | i'm terrified of a pic in the locker rooms, afterall
| |
| 15:38 | <_UsUrPeR_> I am too. I'm all pasty and out-of-shape. no one needs to see that.

| 15:39 | i find it funny though. I walked by a clasroom today and heard the ringtone, the teacher, 45 years old, was blissfully unaware
| |
| 15:39 | <_UsUrPeR_> cell phone interdictors like they use in secret clearence DoD installations?
| |
| 15:39 | ...with flame throwers attached
| |
| 15:39 | <robehend1> sadly illegal in MN public areas
| |
| 15:39 | <_UsUrPeR_> whaaaaat?
| |
| 15:39 | oh, I've got it
| |
| 15:39 | <robehend1> state funded is a no no, invasion of privacy
| |
| 15:40 | i tried, oh god did i try
| |
| 15:40 | i wanted a jammer though
| |
| 15:40 | <_UsUrPeR_> set up a wireless cell repeater in the school, and then forward all calls coming to it to a horrible 1-900 number
| |
| 15:40 | being the closest tower, it will be used first
| |
| 15:40 | ...and also attach a flamethrower to that
| |
| 15:40 | just "for good measure"
| |
| 15:41 | m4xx has joined #ltsp | |
| 15:42 | <robehend1> also illegal, sadly
| |
| 15:42 | though we did it as a demonstration once, kids freaked
| |
| 15:43 | mostly cuz we hooked the fake tower into a projector, and had it display the numbers attempting to dial out
| |
| 15:44 | fricken cyber security laws
| |
| 15:46 | <_UsUrPeR_> bummer
| |
| 15:47 | Perhaps failing children who misbehave would be a good way to do it
| |
| 15:47 | <robehend1> But..no children can be left behind!
| |
| 15:47 | <_UsUrPeR_> bs. there's thousands left behind of their own volition
| |
| 15:47 | <robehend1> but we cant leave them behind either!
| |
| 15:47 | we've gotta get them an indiviual education plan and drag them kicking and screaming until they drop out!
| |
| 15:48 | <_UsUrPeR_> this is why private schools exist :)
| |
| 15:48 | I can tell we are both jaded
| |
| 15:48 | <robehend1> nearest private is 130 miles from me, sadly
| |
| 15:48 | <_UsUrPeR_> holy carp where are you?
| |
| 15:48 | <robehend1> Minnesota
| |
| 15:48 | aka, the land god shat on
| |
| 15:49 | we have one charter school around, but it has 70 kids enrolled
| |
| 15:49 | <_UsUrPeR_> huh. how's the weather over there?
| |
| 15:50 | <robehend1> currently -4 degrees with a 15 mph wind
| |
| 15:50 | <_UsUrPeR_> it's pretty awful in Michigan. I am guessing 3x that
| |
| 15:50 | <robehend1> nah, i'm far away from the lake, so i dont have the bitter chill of death
| |
| 15:51 | <_UsUrPeR_> well that's good then
| |
| 15:52 | <robehend1> mhmm
| |
| 15:52 | looks like i'm building some tone frequency detectors for classrooms
| |
| 15:52 | <_UsUrPeR_> so any luck figuring out your localapps situation?
| |
| 15:53 | <robehend1> havent had a chance, not since this latest debacle. lemme remote in
| |
| 15:53 | what am i looking for again?

| |
| 16:09 | <Gadi> m4xx: dualhead still?
| |
| 16:10 | <m4xx> as well as other non ltsp related things ;]
| |
| 16:14 | * Gadi is happy to not be the only one who tears his hair out :) | |
| 16:14 | <Gadi> for me today it was mainly the crappiness of rdesktop and seamlessrdp
| |
| 16:15 | any of you folks have the pleasure of seamlessrdp against a w2k8 terminal server?
| |
| 16:16 | _UsUrPeR_: did you ask me something earlier?
| |
| 16:17 | * Gadi thinks he rushed out too quickly | |
