| 04:56 | <miks> Thanks for all the help earlier Vagrantc, alkisg, and Hyperbyte
| |
| 04:58 | I tried the shutdown.desktop example, and it produced the same result as the Gnome Shutdown button, which is to log out of the session back to the login screen, but not shut the actual thin-client down
| |
| 04:59 | I think the answer to most of my remaining issues are to upgrade from 9.10, to Edubuntu 11.10 and troubleshoot any issues that arise along the way rather than trying to troubleshoot an out-of-date system
| |
| 05:00 | I'll just need to bring in a test server, so I can do my testing on 11.10 without overwriting 9.10 and leaving myself in a precarious spot with a half-working system :-)
| |
| 05:00 | <vagrantc> virtual machines are your freind.
| |
| 05:01 | you can also use the same application server, but different LTSP servers (serving up the root filesystem) ... the load on the root server itself is pretty small.
| |
| 05:02 | that way you can test the effects of the various LTSP versions
| |

| 05:06 | <miks> Yeah, I'll be using a VM for sure
| |
| 05:06 | For anyone interested, here's a photo of the Before and After in our school lab: http://i41.tinypic.com/358dok7.jpg
| |
| 05:07 | It's taken weeks to remodel the room entirely, and finishing the IT portion of the LTSP lab is the final step. I'm sure you'll all hear from me in the coming weeks as I work my way up to 11.10
| |
| 05:07 | Thanks again for the help!
| |
| 05:08 | <vagrantc> miks: thanks for the pictures!
| |
| 05:08 | <miks> And vagrantc: maybe I'll see you at FG when I'm picking up pieces from Nate
| |
| 05:08 | <vagrantc> always glad to know it's helpful
| |
| 05:08 | miks: yeah, be sure to ask if i'm around
| |
| 05:09 | <miks> Our grant from FG has been essential to making this happen
| |
| 05:09 | Will do

| 10:08 | <zoobab> hi
| |
| 10:09 | <Hyperbyte> Hello.
| |
| 10:09 | And how are you doing today? :)
| |
| 10:09 | <zoobab> fine, playing with edubuntu
| |
| 10:10 | does LTSP supports NX?
| |
| 10:10 | <Hyperbyte> Define "support"?
| |
| 10:11 | <zoobab> i
| |
| 10:11 | are there packages for nx?
| |
| 10:11 | <Hyperbyte> LTSP can launch screen scripts on requests, on different screens. By default it's just LDM (the LTSP login manager), but you can also enable screen scripts for rdesktop, to log in to RDP servers
| |
| 10:11 | <zoobab> I tried edubuntu last week and played a youtube vidoe, it was pumping 100mpbs
| |
| 10:12 | <Hyperbyte> There might be screen scripts for NX, or it might be not hard to make one.
| |
| 10:12 | zoobab, does that surprise you?
| |
| 10:12 | Transmitting raw video over the network uses a lot of bandwith.
| |
| 10:12 | <zoobab> yes
| |
| 10:12 | I was not surprised
| |
| 10:12 | <Hyperbyte> :)
| |
| 10:13 | Usually, if you don't have a very fast network, you'll want to run Firefox as a local app.
| |
| 10:13 | It'll integrate into the desktop like any other application, but will run locally on the client, so it's image isn't transmitted over network.
| |
| 10:15 | <zoobab> otherwise, I am interested in booting over wireless
| |
| 10:16 | I was thinking to compile a small openwrt x86 with kexec tools
| |
| 10:16 | and some python with wicd-curses
| |
| 10:16 | <Hyperbyte> I have no idea what the last two things you just said mean.
| |
| 10:17 | <zoobab> you know openwrt?
| |
| 10:17 | <Hyperbyte> But booting over some network that won't support PXE boot (internet, wireless) is usually accomplished by turning the TFTP boot image into a USB image.
| |
| 10:18 | I know what OpenWrt is, yes.
| |
| 10:19 | I don't think LTSP will run very well over wireless though. Fat clients maybe, probably not thin clients.
| |
| 10:19 | <zoobab> even with NX?
| |
| 10:19 | <Hyperbyte> Why would you want LTSP in that case?
| |
| 10:19 | LTSP = PXE boot, remote X.
| |
| 10:20 | If you're not gonna use remote X, and don't wanna PXE boot, there's no point in having LTSP.
| |
| 10:20 | You'll just want a USB bootdisk with an NX client on it.

| 14:14 | lifeboy has joined IRC (lifeboy!~lifeboy@196.215.143.190) | |
| 14:14 | <lifeboy> vagrantc: I did some investigation and the 2.6.34.1-vortex86-sg kernel is a special build done by DMP (if think) for the Vortex86DX/MX chipset based machines. And, yes, it's built without NBD support since it's meant to boot from a CF drive in the machine, not via PXE. So I'm getting the source to add NBD support and build a new kernel.
| |
| 14:14 | If that fails (probably because I'm not experienced at it) I will attempt to add the kernel modules to the standard Lucid kernel and see if I can get that working.

| 14:16 | <laurei> can anyone point me to any reliable information about setting up /home directories on an external server
| |
| 14:18 | <Hyperbyte> laurei, for an LTSP server?
| |
| 14:18 | alkisg has joined IRC (alkisg!alkisg@ubuntu/member/alkisg) | |
| 14:19 | <laurei> yes Hyperbyte I'm using fat clients
| |
| 14:19 | <Hyperbyte> Ah, with fat clients it's easy
| |
| 14:19 | Set up an NFS server on your fileserver
| |
| 14:19 | <laurei> i had that feeling but its a black hole in Google it seems
| |
| 14:20 | <Hyperbyte> https://help.ubuntu.com/community/SettingUpNFSHowTo
| |
| 14:20 | Really?
| |
| 14:20 | That's the link I found
| |
| 14:20 | Set up NFS on your fileserver, then set NFS_HOME in lts.conf
| |
| 14:20 | !lts.conf
| |
| 14:20 | <ltsp> Hyperbyte: lts.conf: http://manpages.ubuntu.com/lts.conf

| 14:20 | jason has joined IRC (jason!ada36451@gateway/web/freenode/ip.173.163.100.81) | |
| 14:20 | <Hyperbyte> Mind you, this won't work with thin clients. Or it'll work, but give mixed results. I moved all my storage to my LTSP server because of that.
| |
| 14:20 | But for fat clients it shouldn't be a problem at all.
| |
| 14:21 | jason is now known as Guest99358 | |
| 14:21 | <Guest99358> hi
| |
| 14:21 | thoughts of this box with ltsp?
| |
| 14:21 | http://bytespeed.com/thin-clients/t160-thin-client
| |
| 14:21 | the VIA processor raises an eyebrow to me
| |
| 14:23 | <Hyperbyte> Thin clients or fat?
| |
| 14:24 | <laurei> Hyperbyte: I just would like the flexibility of nonLTSP and LTSP machines using the same share, also thin clients so it doesn't matter where it is, maybe using the LTSP server as the /home base is best.
| |
| 14:24 | <Hyperbyte> laurei, definitely. Think of it this way... your non LTSP clients will go from client to server... no matter where your storage is.
| |
| 14:25 | If your LTSP server has remote storage, and you use thin clients, it goes from client to server to server.
| |
| 14:25 | And that's not even such a problem speed-wise, but I had lots of problems with file locks and file permissions not being transferred properly from the file server, via the ltsp server, to the ltsp client.
| |
| 14:26 | mgariepy has left IRC (mgariepy!~mgariepy@ubuntu/member/mgariepy, Quit: Leaving) | |
| 14:26 | <laurei> great, then that's settled, i'll just whack on some extra storage on the server and export via nfs
| |
| 14:27 | Gremble has joined IRC (Gremble!~Ben@cpc12-aztw24-2-0-cust146.aztw.cable.virginmedia.com) | |
| 14:27 | <laurei> what will I do if I'd like windows machines to access, this?
| |
| 14:27 | mgariepy has joined IRC (mgariepy!~mgariepy@ubuntu/member/mgariepy) | |
| 14:28 | <alkisg> Export it with samba too
| |
| 14:29 | <Hyperbyte> https://help.ubuntu.com/community/Samba/SambaServerGuide
| |
| 14:29 | <laurei> so it's feasable, i thought NFS and SMB would break eachothers locks or something, i have no idea really, just bad experiences ;)
| |
| 14:29 | <Hyperbyte> They won't.
| |
| 14:30 | You can have sshfs (filesystem over SSH, LTSP uses that for home directories) for fat and thin clients, NFS for non-LTSP Unix clients and Samba for Windows clients.
| |
| 14:32 | <laurei> awesome thanks.
| |
| 14:32 | ldap however :S
| |
| 14:33 | if you have any links for LDAP auth on fatclients it'd be great. i've actually tried a few tutorials and it seems installed but just... nothing.
| |
| 14:34 | <alkisg> Why do you need ldap on fat clients?
| |
| 14:34 | <cliebow_> From bts..Scotties Sccotsman story..http://169.244.3.137/scotsman.m4v
| |
| 14:34 | <alkisg> You can do whatever you want on the ltsp server
| |
| 14:35 | laurei: and then fat clients with authenticate with ssh against the server as usual, even if the server is an ldap client itself
| |
| 14:35 | <laurei> yes sorry , i meant for fat clients
| |
| 14:35 | <alkisg> So what I mean is that LDAP isn't at all related to LTSP
| |
| 14:35 | <laurei> so i just google ldap not ldap ltsp, makes sense
| |
| 14:36 | <alkisg> Right, there's an ubuntu wiki page for that
| |
| 14:36 | (or 3 :))
| |
| 14:36 | <laurei> LDAP so much easier on centos
| |
| 14:36 | <Gadi> alkisg: you guys made it to Mickey Mouse's clubhouse ok?
| |
| 14:37 | <alkisg> Gadi: hehe, yup, after losing a couple of planes first :D
| |
| 14:37 | <Gadi> what time did you finally arrive?
| |
| 14:37 | <alkisg> 11something, I believe
| |
| 14:38 | <laurei> thanks for this alkisg Hyperbyte
| |
| 14:38 | <Gadi> wow
| |

| 16:25 | <mnevans> Hello LTSP world. I'm having trouble properly setting display at my client, which is an AMD E-350 based box (Zotac Zbox). Server is AMD 6164 based with integrated graphics. I'm not finding how and where to set the display properly either at the console or at this client. Modifying the lts.conf in /var/lib/tfptboot/ and the /etc/X11/xorg.conf file in either the server or thin client directories doesn't seem to do anything. I am getting instead what se
| |
| 16:27 | <alkisg> " I am getting instead what se" ==> the line was cut at that point, it was too long
| |
| 16:29 | <mnevans> Sorry! To continue: I am getting instead what seems to be a stock set of possible screen resolutions, none of which fit my 1920x1080 and 1680x1050 displays. System is Ubuntu 10.10 and LTSP 5. Thanks in advance.

| 16:34 | <mnevans> Here is output of xrandr at present: http://pastebin.com/WDJsckSn
| |
| 16:37 | <Gadi> mnevans: what driver is the client using?
| |
| 16:38 | mnevans: can you paste the *client's* /var/log/Xorg.7.log?
| |
| 16:38 | <mnevans> Thank you. I'm not sure how to tell that.
| |
| 16:38 | <vmlintu> mnevans: what graphics chip is in that box?
| |
| 16:38 | <mnevans> Ah, remind me how to get an xterm on the local box?
| |
| 16:39 | <alkisg> !localxterm
| |
| 16:39 | <ltsp> alkisg: localxterm: while sitting on a thin client, open a gnome terminal. In that, run: ltsp-localapps xterm. An xterm will open. That xterm runs locally, so any commands you enter there are executed directly on the client.
| |
| 16:39 | <alkisg> lspci -nn -k | grep -A 2 VGA on that
| |
| 16:40 | <mnevans> Great - thanks. output of lspci is here: http://pastebin.com/XZsCrdJN
| |
| 16:42 | Xorg.7.log is a large file; do you want me to grep it for anything and pastbin that?
| |
| 16:43 | Gadi, I do see this at the end of Xorg.7.log on the local box: Using system config directory "/usr/share/X11/xorg.conf.d"
| |
| 16:43 | Gadi: correction: near the beginning of the logfile.
| |
| 16:45 | <vmlintu> all the zotacs I've used have either intel or nvidia graphics - maybe that one needs fglrx?
| |
| 16:45 | <Gadi> mnevans: one way to pastebin the whol file would be to "apt-get install pastebinit" on the client and use the "pastebinit" utility. If you do not want to do that, read through the file and look to see what driver it uses
| |
| 16:46 | mnevans: the fact that xrandr shows "default" as the channel says that whatever driver it is choosing, it does not support xrandr channels well
| |
| 16:46 | also, if this is DVI, I would hazard a guess that it is not able to get the proper modes from the monitor
| |
| 16:46 | specifically the sync rates
| |
| 16:47 | the best bet is to use the best driver
| |
| 16:47 | barring that, you can try forcing sync rates in lts.conf with X_HORZSYNC and X_VERTREFRESH
| |
| 16:47 | then, use XRANDR_MODE_0 to select your mode
| |
| 16:48 | <mnevans> Gadi, vmlintu: here are specs on this zbox: http://www.newegg.com/Product/Product.aspx?Item=N82E16856173022;
| |
| 16:48 | sync rates are:
| |
| 16:48 | hang on, asus display VE224H...
| |
| 16:49 | Horizontal Refresh Rate30 - 83 kHz
| |
| 16:49 | Vertical Refresh Rate50 - 76 Hz
| |
| 16:49 | graphics on the zbox are by:
| |
| 16:50 | <Gadi> great. Try: X_HORZSYNC = "30-83" and X_VERTREFRESH = "50-76" in your /var/lib/tftpboot/ltsp/i386/lts.conf
| |
| 16:50 | <mnevans> Onboard Video: AMD Radeon HD 6310
| |
| 16:50 | <alkisg> A driver isn't listed in lspci -k, so it's probably using Vesa, and Vesa only supports a small list of modes. You probably need another driver, e.g. flxgr.
| |
| 16:50 | To my experience, even xrandr --newmode doesn't work with Vesa
| |
| 16:50 | <Gadi> right
| |
| 16:50 | <mnevans> @ Gadi: OK. I am going to add the X_HORZSYNC and X_VERTEFRESH to my lts.conf... standby

| 16:51 | <Gadi> mnevans: it may still be likely what alkisg says. In which case, find the ubuntu wiki entry for adding flgrx to the distro version you are on
| |
| 16:51 | <mnevans> @ alkisg: I think you're right - I had no luck using cvt and xrandr to add the modes.
| |
| 16:52 | <Gadi> and add it in the chroot
| |
| 16:53 | <mnevans> OK, here is my lts.conf in /var/lib/tftpboot/... : http://pastebin.com/CcMLECU4
| |
| 16:53 | Do I need to delete the X_MODE_O, X_CONF lines?
| |
| 16:53 | Looking for the wiki for flgrx for ubuntu 10.10...
| |
| 16:53 | <Gadi> yes
| |
| 16:53 | X_CONF overrides everything else
| |
| 16:54 | if you use X_CONF, I believe it will ignore the other X* params
| |
| 16:54 | <mnevans> Would this be the right instructions for flgrx? http://wiki.cchtml.com/index.php/Main_Page
| |
| 16:54 | @Gadi: commenting out the X_CONF and X_MODE_O lines.

| 16:55 | <mnevans> [I meant, X_MODE_0]
| |

| |
| 16:59 | <Gadi> mnevans: in the chroot
| |
| 17:00 | <mnevans> Gadi: Sorry, do what in the chroot (/var/lib/tfptboot/...)?
| |
| 17:01 | * vagrantc heads west | |
| 17:01 | <Gadi> that's not the chroot - that's the tftp directory
| |
| 17:01 | mnevans: do this:
| |
| 17:01 | sudo ltsp-chroot
| |
| 17:01 | (does that work on your version)?
| |
| 17:01 | if not, try: sudo /usr/share/ltsp/scripts/ltsp-chroot
| |
| 17:02 | <mnevans> yes, I get a prompt for root@zero/#
| |
| 17:02 | <Gadi> excellent
| |
| 17:02 | <mgariepy> ltsp-chroot -p (to mount proc)
| |
| 17:02 | <Gadi> now you are in your chroot
| |
| 17:02 | ah
| |
| 17:02 | yeach you might need that
| |
| 17:02 | type: exit
| |
| 17:02 | then: sudo ltsp-chroot -p
| |
| 17:02 | <mgariepy> Gadi, we should perhaps change the prompt and add a lock file for this script

| |
| 17:03 | <mnevans> Here I am, not finding ltsp-chroot in the manpages... :-)
| |
| 17:03 | <Gadi> mnevans: once you are in the chroot again...
| |
| 17:04 | do: apt-get update
| |
| 17:04 | apt-get install fglrx
| |
| 17:04 | <mnevans> So: sudo ltsp-chroot -p then?
| |
| 17:04 | <Gadi> yes
| |
| 17:04 | (your chroot == /opt/ltsp/i386; ltsp-chroot is a script to chroot in there so you can add things to the OS seen by the client)
| |
| 17:05 | <mnevans> Got it - thank you. I keep a log of changes so I can recreate things when I break them...
| |
| 17:06 | OK... installing fglrx and friends.
| |
| 17:06 | <Gadi> once you have that package installed, if there are any other changes you need to make to the client OS, do it there. When you are done, type exit to return to your server OS
| |
| 17:06 | Once you are back at the server OS, run: sudo ltsp-update-image --arch i386

| |
| 17:09 | someones else here may know better
| |
| 17:09 | *someone
| |
| 17:10 | <mnevans> OK installed the fglrx driver, now will do the update-kernels command, except I am going to omit the --arch option as the client is amd64
| |
| 17:10 | <Gadi> is your chroot amd64?
| |
| 17:11 | <mnevans> yes
| |
| 17:11 | <Gadi> ah, then it is in /opt/ltsp/amd64?
| |
| 17:11 | carry on, then
| |
| 17:11 | :)
| |
| 17:11 | <mnevans> Yes
| |
| 17:12 | Can I also update the sshkeys?
| |
| 17:12 | <Gadi> you don't have to
| |
| 17:12 | <mnevans> OK then. Reboot the client now?
| |
| 17:12 | <Gadi> yup
| |
| 17:12 | <mnevans> OK - I am writing from the client, so over and out for a bit...

| |
| 17:13 | Updating /var/lib/tftpboot directories for chroot: /opt/ltsp/i386
| |
| 17:13 | (I have i386 and i686 clients.)
| |
| 17:13 | I mean, amd64 not i686
| |
| 17:14 | <Gadi> that was when you updated kernels or image?
| |
| 17:14 | <mnevans> I believe, kernels. I didn't do update-image - whoops, better do that.
| |
| 17:14 | <Gadi> yup
| |
| 17:15 | <mnevans> Doing that now... sorry, trying to make notes and follow instructions at the same time. I need to learn to multiprocess... ;)
| |
| 17:15 | Done.
| |
| 17:15 | Restarting (can I just restart the xsession, or reboot the entire os?)

| 17:25 | <Gadi> mnevans: did your xrandr output change?
| |
| 17:25 | <mnevans> OK, I tried that using the 'vendor's driver interface' and got an error: no ati driver installed. It says I can either install an appropriate ati driver or configure using aticonfig. Assuming this really is an either/or, I'll try the latter?
| |
| 17:25 | Gadi: wait a minute... no.
| |
| 17:26 | <Gadi> the key is to get the ati driver installed in the client chroot
| |
| 17:26 | installing it on the server doesn't do you any good
| |
| 17:26 | <mnevans> Well, it might help, as that graphics is integrated on an amd server board as well... But back to the client.

| |
| 17:31 | Downloading it...
| |
| 17:31 | Now how to install it as chroot?
| |
| 17:35 | OK - I downloaded the driver, then moved it into /usr/src/ati_catalyst directory, under chroot (/opt/ltsp/amd64/).

| 18:20 | <mnevans> @ Gadi, mgariepy, I'm stuck here. fglrx install at client didn't fix problem; ati install @ client didn't go. Should I reinstall fglrx, then try using lts. conf to set display parameters?
| |
| 18:25 | <alkisg> mnevans: what's the error message you get when you try to install it to the chroot?
| |
| 18:25 | lifeboy: remove "quiet splash" from pxelinux.cfg/default, reboot the client, and paste the last lines you see before the panic
| |
| 18:26 | E.g. if it panics at mount, you can use "break=mount" in pxelinux.cfg/default
| |
| 18:26 | <mnevans> alkisg, thanks. It failed at wanting manual install of dpkg-deb, then at build-essential. I'm just manually installing the second of these.
| |
| 18:27 | <alkisg> mnevans: how are you trying to install it? You shouldn't ever have to manually install packages in Debian/Ubuntu, that's what package dependencies are for.
| |
| 18:27 | (I mean, you shouldn't ever have to manually install dependencies)
| |
| 18:28 | <mnevans> alkisg, Right. I was just following directions when the amd installer barfed. It said, try installing dkpg-dep manually. So
| |
| 18:28 | <alkisg> Maybe the directions are broken, link?
| |
| 18:28 | <mnevans> I asked for 'apt-get install dpkg-dev'
| |
| 18:29 | Maybe. I had originally put the run.sh in /usr/src/ati_catalyst/, now I have it in /usr/share/ati_catalyst.
| |
| 18:30 | The installer appears to finish successfully without the --buildpkg Ubuntu/maverick switch. But I don't see any useful result from that.
| |
| 18:31 | <alkisg> After the driver is installed in the chroot, you probably need to use either X_CONF in lts.conf, or X_MODULEsomething
| |
| 18:32 | And of course ltsp-update-image etc
| |
| 18:32 | <mnevans> It seems to want debhelper fakeroot execstack. OK to run apt-get install debhelper fakeroot execstack, then try again the amd .sh script?
| |
| 18:32 | I do have the following in lts.conf:
| |
| 18:33 | XRANDR_MODE_0 = 1920x1080
| |
| 18:33 | <alkisg> "it seems to want" => I wouldn't have any idea unless you pastebined the actual output
| |
| 18:33 | Don't put any XRANDR options at all
| |
| 18:33 | <mnevans> and refresh settings.
| |
| 18:34 | <alkisg> No refresh settings either
| |
| 18:34 | <mnevans> OK - I am commenting out all of that!
| |
| 18:34 | <alkisg> The only things you'll need is X_CONF or X_MODULEwhat'sitsname
| |
| 18:34 | <mnevans> Are you sure? I thought Gadi was suggesting just the opposite.
| |
| 18:35 | <lifeboy> alkisg: "you can use "break=mount" in pxelinux.cfg/default" is what I was looking for. I already have "quiet splash" removed, but can't paste from the TC since the kernel panics before I can do anything, just after
| |
| 18:35 | "Begin: Running /scripts/nfs-top ...
| |
| 18:35 | Done."
| |
| 18:35 | <alkisg> lifeboy: distro/version?

| 18:37 | <mnevans> I am going to pastebin the output of the sh script: http://pastebin.com/mqzYFHPC
| |
| 18:39 | @alkisg, I sudo apt-get installed debhelper fakeroot execstack, then reran the script. It appears to be building the package....
| |
| 18:39 | <alkisg> mnevans: yes it's still missing packages, do that
| |
| 18:40 | <lifeboy> alkisg: Ubuntu 10.04 32bit
| |
| 18:42 | It's the same client I've been working on since the weekend and asked about here yesterday. Vortex86MX processor without cmov, so I need Lucid. I just don't seem to get it to load the r6040 ethernet module.
| |
| 18:42 | <alkisg> Right, after nfs-top, configure-networking is called
| |
| 18:42 | So that's where it crashes for you
| |
| 18:43 | <lifeboy> mount=break does nothing?
| |
| 18:43 | <alkisg> How did you get the module? You self-compiled?
| |
| 18:43 | <mnevans> alkisg, the installer completed, made some additional .debs. I installed those. The ran ltsp-build-kernel, ltsp-build-image in the host.
| |
| 18:44 | Now will reboot client and see what happens?
| |
| 18:44 | <alkisg> lifeboy: it's the opposite, break=mount. But "mount" is after network configuration, so you don't reach that point. You can use "break=top" instead.
| |
| 18:44 | <ogra_> or =premount ;)
| |
| 18:45 | mnevans has left IRC (mnevans!~mnevans@zero.geol.umd.edu) | |
| 18:45 | <lifeboy> I've got the module from the 2.6.34.1-vortex86-sg distro, which doesn't have nbd support compiled in.
| |
| 18:45 | <alkisg> I don't think you can copy modules from different kernel versions and expect them to work
| |
| 18:45 | <lifeboy> If the module is specifically for that distro, will it be refused by Lucid?
| |
| 18:48 | <alkisg> It's not a distro problem only, it's also a problem between kernel versions in the same distro
| |
| 18:48 | The kernel expects all the modules to be compiled with the same kernel header versions

| 18:54 | <mnevans> alkisg, rebooted the client after the install of the ati driver. I still don't see the correct resolution.
| |
| 18:54 | <alkisg> Did you put the lts.conf directives I said above?
| |
| 18:55 | <mnevans> Here is the error message on running amdcccle in the client: "There was a problem initializing Catalyst Control Center Linux edition. It could be caused by the following. No AMD graphics driver is installed, or the AMD driver is not functioning properly. Please install the AMD driver appropriate for you AMD hardware, or configure using aticonfig." sudo aticonfig --initial gives 'no supported adapters detected.'
| |
| 18:57 | <alkisg> (08:54:45 μμ) alkisg: Did you put the lts.conf directives I said above?
| |
| 18:57 | bbiab
| |
| 18:57 | <mnevans> Yes, here is the lts.conf I have now:
| |
| 18:58 | [default]
| |
| 18:58 | CONFIGURE_X=True
| |
| 18:58 | LOCALDEV=True
| |
| 18:58 | SOUND=True

| |
| 18:58 | That's it.
| |
| 18:59 | [if there were other things you said to add, I'm afraid closing the chat without saving the discussion made me lose those... :|
| |
| 19:01 | Should I try pointing to /etc/X11/xorg.conf in lts.conf, and then making a simple xorg.conf there, e.g.

| |
| 19:04 | <mnevans> Oh. Lots to learn...
| |
| 19:04 | <alkisg> mnevans: I suggested above that you need either an X_CONF directive in lts.conf, or a module directive
| |
| 19:04 | You didn't put those
| |
| 19:05 | In the irc /topic you can see the link to the logs, if case you close the client and want to read what you said before
| |
| 19:05 | (the channel is publicly logged)
| |
| 19:05 | <mnevans> OK - now I have X_CONF=/etc/X11/xorg.conf in lts.conf
| |
| 19:05 | <alkisg> And do you have such a file there?
| |
| 19:05 | <mnevans> Now, yes, as follows:
| |
| 19:05 | <alkisg> Pastebin your /opt/ltsp/i386/etc/X11/xorg.conf

| |
| 19:08 | <mnevans> alkisg, Do I have to rebuild the client itself?
| |
| 19:08 | Or just ltsp-update-kernels, image?
| |
| 19:08 | <alkisg> mnevans: just ltsp-update-image, did you run it?
| |
| 19:09 | <mnevans> Yes.
| |
| 19:09 | <alkisg> Once you've booted the client with all that stuff, lts.conf X_CONF etc, you can start troubleshooting
| |
| 19:09 | !localxterm
| |
| 19:09 | <ltsp> alkisg: localxterm: while sitting on a thin client, open a gnome terminal. In that, run: ltsp-localapps xterm. An xterm will open. That xterm runs locally, so any commands you enter there are executed directly on the client.
| |
| 19:09 | <alkisg> E.g. pastebin xorg.0.conf from the localxterm
| |
| 19:09 | /var/log/Xorg.0.log
| |
| 19:09 | *sorry log not conf
| |
| 19:09 | And also, cat /etc/X11/xorg.conf from that localxterm
| |
| 19:12 | <mnevans> OK - rebooting!

| |
| 19:21 | So it was: (1) install new ati driver; (2) configure lts.conf to look for /var/log/tftpboot/etc/X11/xorg.conf; (3) put a very simple xorg.conf there,
| |
| 19:21 | like suggested here: http://wiki.cchtml.com/index.php/Ubuntu_Maverick_Installation_Guide#Installing_Proprietary_Drivers_a.k.a._Catalyst.2Ffglrx

| 22:15 | <miks> Hi all!
| |
| 22:15 | <Hyperbyte> Hi miks!
| |
| 22:16 | <miks> With my lab up and running on 9.10, I'm starting to build a VM so I can do some testing with a newer version of LTSP and Ubuntu
| |
| 22:16 | I'm starting with Edubuntu 11.10, and have already run into a problem
| |
| 22:16 | With 11.04, there was a bug where if you chose NOT to use Unity (which I hate), the option didn;t apply to thin-clients
| |
| 22:17 | Thin-clients still booted unity
| |
| 22:17 | This has been fixed in 11.10, HOWEVER, now it appears they've remove Sabayon (the user profile editor) which I use to lock down student logins
| |
| 22:18 | So I'm stuck between a rock and a hard place. I need to have Sabayon working, and be able to disable Unity on thin clients
| |
| 22:18 | I'm open to suggestions on this one
| |
| 22:19 | a.) What version of Ubuntu should I shoot for in the lab, on my test VM
| |
| 22:19 | b.) Given that version, how do I get around the bugs I mentioned
| |
| 22:20 | As I said, Ubuntu 9.10 is working for now, so I can take a my time a little bit on this one and do some VM testing and really get things smoothed out before I replace the server

| 22:42 | <Hyperbyte> miks, you need to find one version you want and then stick with it, fixing bugs as you go.
| |
| 22:43 | Sabayon doesn't ring a bell, but you can use gcontool-2 to set mandatory Gnome settings.
| |
| 22:43 | I believe there's also a gconf editor GUI.

| 23:05 | <MrDoh2> I have some ltsp question if anyone has a few minutes
| |
| 23:08 | <cliebow> put it out there..i am too far behind to help..someone might
| |
| 23:09 | <MrDoh2> well, 2 things to start... first, does it work/how well in a WAN environmet? Most of the remote sites have a T1 or at most 2 of them
| |
| 23:10 | and second, is netbooting/pxe required? the thin client boxes we invested in won't do it and management doesn't want anything using dhcp even for netbooting, the clients do have xdmcp built in though

| 23:38 | <cliebow> MrDoh2:if you are`gonna netboot thn clients..etherbot or pxe or gpxe is necessary
| |
| 23:39 | your latency in a wan environment may prelude a server hooked to a server on a ti
| |
| 23:39 | though you can do some central server stuff with a fat client that can boot itself
| |
| 23:46 | <MrDoh2> we don't want to netboot, the clients natively come with a xdmcp client and I hope we can connect without netbooting
| |
| 23:49 | we currently use freenx but need something with clustering
| |
| 23:51 | gotta take the kiddos trick or treating but I will be back
