| 00:13 | <alkisg> Good morning
| |
| 00:13 | vagrantc: a gdebi approach to the "install *.debs to the chroot" problem: http://paste.ubuntu.com/383291/ Would you care to see that upstream, or should I just keep it for private use?
| |
| 00:31 | <vagrantc> alkisg: seems reasonable.
| |
| 00:31 | alkisg: unless gdebi-core pulls in an absurb amount of dependencies
| |
| 00:31 | looks pretty minimal
| |
| 00:31 | <alkisg> Nah, it's just 3 mb on my thin chroot
| |
| 00:31 | vagrantc: k, I'll test & submit later on, thanks!
| |
| 00:32 | <vagrantc> alkisg: why the apt_options bit?
| |
| 00:32 | ah, i see ... you have to pass it the --option flag.
| |
| 00:32 | <alkisg> Yup, to pass the apt options that we already have in the ltsp-build-client
| |
| 00:32 | That's a *weird* syntax it has, though...
| |
| 00:33 | <vagrantc> alkisg: no sense using /tmp, though ...
| |
| 00:33 | <alkisg> --option =--y --option=--no-install-recommends etc
| |
| 00:33 | with spaces before the equals !
| |
| 00:33 | <vagrantc> eeyk.
| |
| 00:33 | <alkisg> vagrantc: should I use /var/run/something?
| |
| 00:34 | <vagrantc> alkisg: too tired to comment more :)
| |
| 00:34 | <alkisg> (or cache)
| |
| 00:34 | Thanks anyway :)
| |
| 00:34 | <vagrantc> yeah, /var/cache makes a little sense ...
| |
| 00:34 | i.e. /var/cache/apt/
| |
| 00:34 | or if gdebi uses any conventions...
| |
| 00:34 | <alkisg> OK. I'm deleting the dir anyway, so it shouldn't make any difference...
| |
| 00:35 | <vagrantc> yeah, but good to not mess with /tmp
| |
| 00:35 | <alkisg> OK. Thanks again :)
| |
| 00:36 | * vagrantc wants to purge the world of hard-coded directories in /tmp | |
| 00:36 | <vagrantc> it just sets some bad precedents.
| |
| 00:37 | <alkisg> Heh, I could use mktemp :P
| |
| 00:39 | <vagrantc> i swear i do something similar with another plugin and just leave the directory there...

| 05:29 | <tthorbj> I have Karmic with LTSP. Several users freezes when they are logged in. I've replaced the client, mv'd their homedir, but it's still freezing. Others have no problems, among them me.
| |
| 05:38 | <alkisg> tthorbj: the only "per user freezing" problems I've ever heard of are compiz related... could you try the following command to disable compiz for everyone?
| |
| 05:38 | !disable-compiz
| |
| 05:38 | <ltspbot> alkisg: "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
| |
| 05:40 | <tthorbj> Thanks, I'll give that a try!
| |
| 05:43 | It sounds like a reasonable solution. I can log in to the clients with ssh after they crashes. I copied the client logs from the user that crashed mostly here: http://www.t-t.no/log.tar.gz
| |
| 05:43 | But - I'll hope alkisg's solution works out!

| |
| 07:36 | Do anyone know about this? http://www.mail-archive.com/ltsp-discuss@lists.sourceforge.net/msg37462.html
| |
| 07:36 | shawnp0wers has joined #ltsp | |
| 07:36 | <tthorbj> "The bigger problem is that the client only boots successfully when using
| |
| 07:36 | nbd. We use nfs for stability reasons (nbd became extremely unstable
| |
| 07:36 | once more than a few clients were connected - thin clients would freeze
| |
| 07:36 | frequently, and could only be brought back to life by hard reset,
| |
| 07:37 | unacceptable for a production environment. Back when we set up our first
| |
| 07:37 | Ubuntu/LTSP5 server, 8.04 hardy, we reverted back to nfs, which solved
| |
| 07:37 | the problem). When I switch the new chroot to nfs (still basically
| |
| 07:37 | according to https://help.ubuntu.com/community/UbuntuLTSP/LTSPWithoutNFS
| |
| 07:37 | ), the thin client does boot up but then apparently cannot mount the
| |
| 07:37 | nfsroot, or so it seems - the last output message on the screen is from
| |
| 07:37 | scripts/nfs-bottom saying /root/etc/hostname can't be written because
| |
| 07:37 | it's a read-only filesystem, then there seems to be a call to mountall
| |
| 07:37 | that ends in some sort of timeout. According to the messages on the
| |
| 07:37 | screen from mtab, the root is already mounted on /, but it's still
| |
| 07:37 | trying to mount / and /tmp and fails."
| |
| 07:37 | Comete has joined #ltsp | |
| 07:37 | <tthorbj> It sounds familiar, but strange also - the whole point with thin clients is to have more than just a few...
| |
| 07:37 | <Comete> hi
| |
| 07:39 | i'm back with my sound problem on thinclients :) maybe someone has an idea
| |
| 07:40 | <alkisg> tthorbj: nbd problems are not per-user problems... they affect all the users equally.
| |
| 07:41 | <tthorbj> naturally
| |
| 07:41 | <ogra> and that staement is clearly wrong
| |
| 07:41 | <alkisg> (and btw, with the new nbd-proxy application, nbd should be much more stable)
| |
| 07:41 | <ogra> there are many installs that use nbd in big environments
| |
| 07:42 | <tthorbj> good to hear!
| |
| 07:42 | <Comete> i use LTSP 5.2 on Ubuntu Karmic 32bits and my Thinclients are HP t5145 don't get sound at all or just a few seconds and then nothing. I've tried with another thinclient model and with my laptop and it works, so it's just with those HP Thinclients. I've also backported pulseaudio from lucid without success... so any idea is welcome... :)
| |
| 07:43 | <ogra> find out what sound HW your client has
| |
| 07:43 | <Comete> Realtek ACL262 chipset
| |
| 07:43 | <ogra> i remember there were bugs with snd-hda-intel suspending the device ...
| |
| 07:43 | well, check launchpad, probably you find something, it sunlikely to be pulse
| |
| 07:43 | more likely to be the driver
| |
| 07:44 | vvinet has joined #ltsp | |
| 07:44 | <Comete> sorry ALC262
| |
| 07:44 | ogra: so a kernel upgrade could do the trick ?
| |
| 07:45 | <ogra> no
| |
| 07:45 | check launchpad
| |
| 07:45 | look if you find any bugs related to the sound driver used
| |
| 07:45 | and possible workarounds
| |
| 07:48 | <tthorbj> About freezing client: another thing - it crashes when idle ... could it be dpms-related? https://bugs.launchpad.net/xf86-video-siliconmotion/+bug/136853
| |
| 07:48 | <ogra> didnt you say these clients have VIA hardware ?
| |
| 07:51 | saschas has joined #ltsp | |
| 07:53 | <saschas> hy ltsplers, I need help with lxde on ubuntu 9.10, anyone here that can help??
| |
| 07:53 | <Comete> ogra: bug reported but no workaround :/
| |
| 07:57 | <saschas> o.k., I'll start: problem 1) lxde on the clients shows logout-reboot-shutdown option, and those shutdown the server. if I logout and use the ldm shutdown all is fine
| |
| 07:58 | <ogra> saschas, you need to patch lxde to suppress these items
| |
| 07:59 | just make it check if LTSP_CLIENT is set in your environment and not show them if it is there
| |
| 07:59 | <saschas> hi ogra, how do I do that??
| |
| 08:00 | <ogra> you either edit the code yourself and rebuild the pats of lxde that needed changing or you file a bug and wait for some lxde developer to fix it :)
| |
| 08:00 | *parts
| |
| 08:00 | its definately a problem of the desktop, not an ltsp one
| |
| 08:01 | <saschas> xfce does th same and gnome does not start for some xgl error reasons
| |
| 08:01 | <ogra> !disable-compiz
| |
| 08:01 | <ltspbot> ogra: "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
| |
| 08:01 | <ogra> try that for gnome
| |
| 08:02 | and yes, xfce has a bug open about this issue in launchpad since several years
| |
| 08:03 | <saschas> oh what a fun :-) o.k. better than $MS
| |
| 08:04 | <tthorbj> I tried "xset dpms force off; sleep 5; xset dpms force on", and the client freezed for 5 seconds - it didn't respond to mouse movements and so on. Is this normal behaviour?
| |
| 08:06 | <ogra> saschas, btw: https://bugs.launchpad.net/ubuntu/+source/xfce4-panel/+bug/65010

| 08:20 | <saschas> ogra lots of kisses from belgium, just did the command and all problems are gone. Gnome works, USB does mount an shutdown goes back to ldm so only clients shutsdown :-) Me happy, thanks
| |
| 08:21 | <ogra> great :)
| |
| 08:21 | <saschas> but lxde would be cool if it works with ltsp5, nice, light, fast
| |
| 08:22 | <ogra> indeed

| 08:25 | <anivair> morning
| |
| 08:26 | I'm having sound problems (still) and today I want to make a solid push to get them fixed before management decides that they have to buy a few dozen phones to clog up desks here.
| |
| 08:26 | it seems that I'm having sound issues with softphones. So far I've had sound problems with every type of softphone I've used, though the best has been twinkle, which is only stuttery about 10% of the time
| |
| 08:28 | I know that ltsp is using pulseaudio
| |
| 08:28 | and I know that most softphones think they're using alsa (though I get sound on mine and I don't believe that I even have alsa running)
| |
| 08:28 | So i'm not sure a) how I'm getting any sound at all and b) why I'm getting stutters
| |
| 08:28 | Any help would be appreciated here
| |
| 08:29 | <ogra> alsa is a driver architecture, for sure you have alsa running if you have sound
| |
| 08:29 | pulseaudio is a multiplexing soundserver sitting on top of the driver
| |
| 08:29 | <anivair> any idea what it would be called? ps aux|grep alsa gives me nothing
| |
| 08:30 | got it
| |
| 08:30 | <ogra> its a kernel driver
| |
| 08:30 | there wont be a process
| |
| 08:30 | <anivair> ahh
| |
| 08:30 | there is my issue
| |
| 08:30 | okay, so it's okay for twinkle to use alsa by default. Is the stutter coming from pulseaudio? I don't get the same stutter if I run twinkle on the server.
| |
| 08:31 | but I get it if I run it on a thin client (either off the server or via localapps)
| |
| 08:31 | seems to make no difference
| |
| 08:31 | <ogra> try prefixing the execution of twinkle with the padsp command
| |
| 08:31 | that will foce it through pulse so you can be sure pulse is used
| |
| 08:32 | <alkisg> How can I create .debs out of ltsp-trunk (unreleased)? By putting the /debian directory in the source tree, and calling debuild -b -tc -uc? Or is there a more automated way?
| |
| 08:32 | <ogra> there is a release tool
| |
| 08:32 | <anivair> "padsp twinkle", or "padsp", "twinkle"?
| |
| 08:32 | * ogra forgot how it was called ... ) | |
| 08:33 | <ogra> anivair, the former
| |
| 08:33 | <alkisg> ogra, mkdst?
| |
| 08:33 | <anivair> thanks, I'll give it a shot
| |
| 08:33 | <ogra> yeah
| |
| 08:33 | mkdst
| |
| 08:33 | <alkisg> ogra, thanks, I'll try to have a look at it
| |
| 08:33 | <ogra> warren insisted to have it instead of manually tagging and expüorting from bzr
| |
| 08:33 | <anivair> (also, is padsp already set to run locally, or will I need to put it into the ltsp image?)
| |
| 08:33 | <ogra> i never understood the need for it though :)
| |
| 08:33 | <alkisg> Heh
| |
| 08:34 | Well if copying the /debian dir is quicker, that'll do just fine for my personal testing needs :)
| |
| 08:34 | <ogra> anivair, padsp will use whatever PULSE_SERVER points to if its set
| |
| 08:34 | which in case of a thin client routes the sound to the client pulse server
| |
| 08:34 | but if you really want to do VOIP stuff you definately need to use localapps
| |
| 08:34 | <anivair> so i don't need ot install it into the image to run that command locally?
| |
| 08:35 | <ogra> network latency is to high otherwise
| |
| 08:35 | yes, you install twinkle in your chroot and run ltsp-update-image
| |
| 08:35 | <anivair> I installed twinkle locally
| |
| 08:35 | <ogra> then you start it with the ltsp-localapp prefix
| |
| 08:35 | <anivair> but will adding padsp to the twinkle command mean I have to install somehting else (padsp, probably)?
| |
| 08:35 | <ogra> no, padsp should come with pulse
| |
| 08:36 | <anivair> "ltsp-localapps padsp twinkle"
| |
| 08:36 | thanks
| |
| 08:36 | <ogra> which is installed by default on every ltsp client
| |
| 08:36 | i'm not sure if you need any special quoting for the localapps command
| |
| 08:36 | alkisg, might know :)
| |
| 08:37 | * alkisg isn't using localapps at all, but I can have a quick look at ltsp-genmenu... | |
| 08:37 | <anivair> the quotes aren't part of the command itself. just putting them there so you know that's the exact command I'm using
| |
| 08:37 | <ogra> right, what i mean is something like: ltsp-localapps "padsp twinkle"
| |
| 08:37 | <anivair> oh, i see
| |
| 08:37 | <ogra> thats what i'm not sure about :)
| |
| 08:37 | <anivair> I can try it both ways
| |
| 08:38 | I'm also going ot have to add a script that kills previous twinkle instances before they run it, because a lot of people here are logging out of their session and it isn't killing their local twinkle app
| |
| 08:38 | <alkisg> ltsp-localapps padsp twinkle without quotes should be fine I believe
| |
| 08:39 | <anivair> thanks, alkisg
| |
| 08:41 | saschas has quit IRC | |
| 08:45 | tthorbj has left #ltsp | |
| 08:48 | <anivair> huh
| |
| 08:49 | ltsp-localapps padsp twinkle would not run (neither would ltsp-localapps "padsp twinkle" so I opened a localapps xterm and just entered padsp twinkle to see what the deal is and I get no recognition
| |
| 08:49 | padsp: unknown command
| |
| 08:50 | <ogra> oh, its in the pulseaudio-utils package
| |
| 08:50 | it used to be in pulseaudio once
| |
| 08:50 | <anivair> so I do need to add that package to the ltsp image?
| |
| 08:50 | <ogra> right
| |
| 08:50 | <anivair> because it's on the server, but not in the ltsp image
| |
| 08:50 | well, it'll have to wait a bit, because once I add it, I'll have to rebuild the image and reboot
| |
| 08:51 | <alkisg> pulseaudio-utils rdepends on pulseaudio on my Lucid... anivair what version do you have? 9.04?
| |
| 08:51 | GodFather has joined #ltsp | |
| 08:51 | <anivair> 9.10
| |
| 08:52 | I believe
| |
| 08:52 | :checks to make sure that's karmic:
| |
| 08:52 | yup, it is
| |
| 08:52 | pulseaudio should be installed in ltsp by default
| |
| 08:52 | <ogra> it is
| |
| 08:52 | <alkisg> Yeah you're right, pulseaudio-utils isn't installed by default on karmic chroots
| |
| 08:52 | <ogra> right
| |
| 08:53 | <alkisg> It is on Lucid chroots though ;)
| |
| 08:53 | <ogra> rdepends says nothing :)
| |
| 08:53 | <anivair> fair. I'll add it as soon as I can get these people down for a few minutes
| |
| 08:54 | <ogra> you really shouldnt do your testing on a production machine
| |
| 08:58 | GodFather has quit IRC | |
| 09:02 | Gadi has joined #ltsp | |
| 09:03 | <anivair> right now it's all i've got
| |
| 09:04 | I'm about to set up a test machine, though. So maybe I'll get that in place first.
| |
| 09:04 | (assuming I can duplicate the problems on it)
| |
| 09:08 | <alkisg> Well if you can't, just keep it as your main server :D
| |
| 09:16 | <anivair> heh
| |
| 09:16 | nicely done

| |
| 09:38 | <jammcq> prpplague: hey
| |
| 09:39 | <prpplague> jammcq: you'll never believe who i heard from this week
| |
| 09:39 | jammcq: greg matatall
| |
| 09:39 | <jammcq> oh?
| |
| 09:40 | he still flying helicopters?
| |
| 09:40 | <prpplague> jammcq: hehe, no i think he's grounded these days
| |
| 09:40 | <jammcq> and we're all safer
| |
| 09:40 | <prpplague> jammcq: you know he sold abcs about 3 years ago to a big software company
| |
| 09:40 | <jammcq> oh?
| |
| 09:40 | didn't know that
| |
| 09:41 | <prpplague> jammcq: yea $32m
| |
| 09:41 | <jammcq> oh nice
| |
| 09:41 | hope he got cash
| |
| 09:41 | most deals that involve stock in the new company end up pretty bad
| |
| 09:42 | unless you are mark shuttleworth :)
| |
| 09:42 | <prpplague> hehe
| |
| 09:42 | jammcq: yea from what i understand most of it was cash up front, and the rest was paid out over three years
| |
| 09:43 | jammcq: the new owner wants to get back into thin clients so greg wants me to do an update version of the thin client software
| |
| 09:43 | <jammcq> oh wow
| |
| 09:43 | is greg still employed there?
| |
| 09:45 | <prpplague> jammcq: yea part of the sale was that he stay with the company for 4 years to ease transition and make sure knowledge was passed on
| |
| 09:46 | <jammcq> prolly the longest 4 years of his life
| |
| 09:47 | <prpplague> indeed
| |
| 09:47 | jammcq: hows biz?
| |
| 09:48 | thunsucker has joined #ltsp | |
| 09:48 | <prpplague> jammcq: i have a client interested in trying out openbravo ERP and POS , you used either of those before?
| |
| 09:48 | <jammcq> nice and busy
| |
| 09:48 | just the way I like it
| |
| 09:48 | nope, neither
| |

| 11:17 | <Gadi> so, it seems the mountall errors stem from having a symlink for /etc/mtab
| |
| 11:17 | perhaps, we should do away with that on ubuntu?
| |
| 11:18 | <tthorb> The users still crying over freezing clients... Strangely - it's still just a few users that gets his/her client frozen... Has anyone else ideas of solutions to cases like this?
| |
| 11:18 | (se the log from earlier today)
| |
| 11:20 | Is there, by the way, a solution that "resques" the working space of a user that gets freezed (similar to vnc-disconnect...)
| |
| 11:22 | <Gadi> tthorb: you have to investigate a bit - what are the users doing when they freeze, are there errors in their ~/.xsession-errors files, etc.
| |
| 11:26 | <tthorb> There's a lot of things there... ** (gnome-power-manager:11178): WARNING **: Either HAL or DBUS are not working!
| |
| 11:26 | for example
| |
| 11:26 | <Gadi> tthorb: have you disabled screensavers?
| |
| 11:26 | maybe thats doing it?
| |
| 11:28 | tthorb: try this:
| |
| 11:28 | sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --set --type boolean /apps/gnome_settings_daemon/screensaver/start_screensaver False
| |
| 11:28 | sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults --set --type integer /apps/gnome-power-manager/timeout/sleep_display_ac 0
| |
| 11:28 | and for good measure:
| |
| 11:28 | sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --set --type boolean /desktop/gnome/lockdown/disable_lock_screen True
| |
| 11:29 | <anivair> okay. update on sound issues. If I run padsp twinkle, I can get good sound going out, but I still get a bad stutter on the speaker (headset, but same dif).
| |
| 11:29 | <Gadi> sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults --set --type list --list-type string /apps/panel/global/disabled_applets "[OAFIID:GNOME_FastUserSwitchApplet]"
| |
| 11:29 | anivair: open an ltsp-localapps xterm
| |
| 11:29 | <anivair> I've changed the headset device around in the settings of twinkle to no effect at all as far as i can tell (ie: it not only doesn't make it better, but there is no change, which makes me wonder if that default is doing anything at all)
| |
| 11:29 | <Gadi> and in that xterm, run alsamixer -c0
| |
| 11:29 | <anivair> will do
| |
| 11:29 | <alkisg> Gadi: so if you remove the mtab symlink, it works fine with no error messages?
| |
| 11:29 | <Gadi> maybe you need to adjust volume settings
| |
| 11:29 | alkisg: yes
| |
| 11:30 | <alkisg> Gadi: karmic or lucid?
| |
| 11:30 | <Gadi> but, I believe we symlink for NFS reasons
| |
| 11:30 | on lucid
| |
| 11:30 | alkisg: try it: rm /opt/ltsp/i386/etc/mtab; touch /opt/ltsp/i386/etc/mtab; ltsp-update-image
| |
| 11:31 | alkisg: I am thinking of adding a workaround in the initramfs
| |
| 11:31 | <alkisg> Gadi, ok, I will - is that writeable when the client boots? (bind - mounted)? Or is it read only?
| |
| 11:31 | <Gadi> alkisg: in the case of NFS, not sure
| |
| 11:32 | <tthorb> Gadi: I'll give that a shot
| |
| 11:32 | <Gadi> tthorb: those gconf changes only take effect when the user next logs in
| |
| 11:32 | btw
| |
| 11:32 | <alkisg> Gadi: I tried something like a fat clients implementation in the summer, which booted from the same file system as the server, with NFS, and I think symlinking was required...
| |
| 11:33 | Gadi: so maybe the workaround should only be applied for nbd...
| |
| 11:33 | <Gadi> alkisg: yeah, thats what I was thinking
| |
| 11:33 | in ltsp_nbd
| |
| 11:33 | just to be safe
| |
| 11:33 | <alkisg> Sounds good to me - I got tired of seeing all those mountall errors ;)
| |
| 11:34 | * Gadi would also like to find a way to blank the screen to remove ugliness | |
| 11:34 | <Gadi> its ugly that it overwrites on top of the pxelinux messages
| |
| 11:34 | <alkisg> ugliness? you mean plymounth?
| |
| 11:34 | <Gadi> doesnt instill confidence
| |
| 11:34 | <alkisg> Ah yeah that's plymouth
| |
| 11:35 | * alkisg disables splash by default so he doesn't see any of that :) | |
| 11:35 | <Gadi> also, udhcpc should pipe to /dev/null
| |
| 11:36 | we don't need to see that
| |
| 11:36 | :)
| |
| 11:36 | <alkisg> Should that be done manually? Isn't there a standard method for initramfs tools?
| |
| 11:39 | BTW, the normal output of udhcpc is hidden... (configured at :::::)... and we only see the broadcasting/receiving, which we shouldn't normally see... ???
| |
| 11:49 | <Gadi> ah, alkisg, can we do this
| |
| 11:49 | if "quiet" is on the commandline, then no output from udhcpc
| |
| 11:49 | otherwise, output
| |
| 11:50 | * Gadi assumes all the broadcasting stuff is on stderr? | |
| 11:50 | <alkisg> Gadi, I'll have a look at it, to see what other initramfs scripts do, there should be a standard way to do that without checking cmdline...
| |
| 11:51 | If the normal output is on stderr, maybe we should just redirect it to stdout
| |
| 11:51 | i.e. udhcp 2>&1...
| |
| 11:52 | as the dhcp handshake doesn't sound like an error message to me ;)
| |
| 11:53 | <Gadi> looks like log_begin_msg and log_end_msg if "quiet" != "y"
| |
| 11:54 | I'll fix it up
| |
| 11:56 | <alkisg> Go go Gadi!
| |
| 11:56 | /me is in the middle of trying an "install all debs from a directory" plugin...
| |
| 11:56 | <anivair> Gadi: I checked alsamixer. everything looks fine
| |
| 11:56 | I have audio, but it's stuttery (in and out)
| |
| 11:57 | <Gadi> anivair: if you play with the levels, does it help?
| |
| 11:57 | <anivair> now, running padsp twinkle, I get really good audio via the microphone, but terrible audio coming back
| |
| 11:57 | nah, it just makes it louder or softer
| |
| 11:57 | right now I've got twinkle set to use my default sound (because if I try to set it ot use anything else it fails to validate the device)
| |
| 11:58 | but I'm not sure why the sound would be perfect going out, but not perfect coming in
| |
| 11:58 | <Gadi> anivair: try running: pasuspender -- twinkle
| |
| 11:59 | <anivair> will do
| |
| 11:59 | <Gadi> (from the local xterm)
| |
| 12:11 | ogra_cmpc has quit IRC | |
| 12:13 | <anivair> 1/4 victory
| |
| 12:13 | that is, if I run pasuspender -- twinkle and set the speaker and mic optionms inside twinkle to the usb device, i get great audio
| |
| 12:14 | however, for some reason, the employees don't have the same sound options I have
| |
| 12:14 | when they optn twinkle (still ltsp-localapps) they only have 2 options for devices.
| |
| 12:16 | I have ALSA: plughw:0,0: VIA 82C686A/B rev50.
| |
| 12:16 | they only have ALSA: Default and ALSA: other
| |
| 12:16 | no idea why, but if I could get them access to the same options I have it would help a lot
| |
| 12:16 | any thoughts?
| |
| 12:21 | the account I log in with is the admin account, but all that means is that I'm in the sudo file. I don't think there's a difference between my account and anyone else's account.
| |
| 12:21 | <Gadi> anivair: ok a few things
| |
| 12:21 | 1. compare the output of "id" for your user as for the others
| |
| 12:21 | pay attentions to the groups
| |
| 12:21 | such as "audio"
| |
| 12:21 | <anivair> bah ... i think you just solved it
| |
| 12:22 | I added myself to the audio group earlier to test kiax
| |
| 12:22 | der
| |
| 12:22 | let me try that
| |
| 12:22 | <Gadi> ah, ok
| |
| 12:22 | then I dont need #2
| |
| 12:22 | :)
| |
| 12:22 | <anivair> heh
| |
| 12:22 | xet7 has joined #ltsp | |
| 12:22 | <Gadi> note: pasuspender suspends the pulseaudio server until the client closes
| |
| 12:23 | which probably means you wont have other sounds until you close twinkle
| |
| 12:23 | ogra_cmpc has joined #ltsp | |
| 12:23 | <anivair> twinkle is the only thing I need sounds for
| |
| 12:24 | groups are set at login, yes? So when i add someone, they have to reboot?
| |
| 12:24 | <Gadi> yeah - or at least re-login, though reboot would prolly be the surest way
| |
| 12:25 | <anivair> last question before I go play with this: if I'm running the app locally, will the /etc/group file still control their groups, or will I need to edit /opt/ltsp/i386/etc/group as well?
| |
| 12:26 | nevermind, looks like a symlink
| |
| 12:26 | <Gadi> dont touch the one in the chroot
| |
| 12:26 | it gets magically written upon ldm login
| |
| 12:26 | we do a lot of magic in the chroot
| |
| 12:27 | alkisg has quit IRC | |
| 12:29 | alkisg has joined #ltsp | |
| 12:32 | <anivair> bam ... that seems to have solved the issue.
| |
| 12:33 | I set the device in twinkle, running it with pasuspender, and that is working
| |
| 12:33 | I don't suppose you can tell me what pasuspender does, can you?
| |
| 12:33 | <Gadi> cool
| |
| 12:33 | sure, though, so can man pasuspender
| |
| 12:33 | pasuspender suspends the pulseaudio server
| |
| 12:34 | while that particular client runs
| |
| 12:34 | so, basically, the overhead of pulseaudio is mucking with your sound quality
| |
| 12:34 | better if you go straight to ALSA
| |
| 12:35 | * Gadi wonders whether we need to investigate our pulseaudio daemon options to see if they can be improved... | |
| 12:37 | * Gadi found similar issues the other day with rdesktop audio quality in the rdesktop screen script | |
| 12:37 | <Gadi> tho, it was likely also due to the fact that pulse, rdesktop, and Xorg were competing for cpu cycles
| |
| 12:39 | alkisg: udhcpc does not seem to want to be silent - its almost like the output is dmesg or syslog type output.... hmm....
| |
| 12:44 | alkisg: does udhcpc die and get restarted in rootfs space? or does it persist?
| |
| 12:45 | <anivair> hmm ... well, running it with pasuspender gives me great audio when they place calls, but apparently they now can't answer calls. maybe the ringer is gumming them up? I'll check into it
| |
| 12:46 | <alkisg> Gadi: it persists, and calls a script whenever the lease expires
| |
| 12:46 | <Gadi> hmm, foo
| |
| 12:47 | ooh... I have an idea...
| |
| 12:47 | <alkisg> Gadi goes bug hunting :)
| |
| 12:48 | (btw, that calling-a-script-when-the-lease-expires needs rewriting... I should get to it someday :()
| |
| 12:48 | <anivair> that was it
| |
| 12:48 | I hadn't changed the ringer
| |
| 12:49 | so it was trying to call pulseaudio and gumming up the works
| |
| 12:49 | fixed now
| |
| 12:49 | honestly, I think this may have solved the issue. we'll see
| |
| 12:49 | I'm optimistic, though'
| |
| 12:49 | <Gadi> we're nothing if not optimistic here
| |
| 12:50 | :)
| |
| 12:50 | <anivair> indeed
| |
| 12:56 | <tthorb> I had a question about a vnc-like behaviour... Some of my users clients are unstable, and to avoid mutiny it would be nice if their work where saved... (Another thing is that some programs, like firefox, hangs after shutdown of the client, and have to be killed from a terminal... not user friendly...:( )
| |
| 12:58 | <Gadi> tthorb: there is no session persistence with X -> for that, you would need a solution like NX or VNC, as you say
| |
| 12:59 | tthorb: as for programs hanging, are the users logging off or just pulling the plug?
| |
| 13:02 | <tthorb> The programs are not hanging. It's the client...
| |
| 13:03 | Everything looks fine from the console - I can actually log in to the client!
| |
| 13:03 | But - to get the client up and go again - they have to pull the plug.

| 13:30 | <alkisg> Grrr stupid google-chrome... I install it with ltsp-build-client's EXTRA_MIRROR, so it goes into sources.list, and upon installation it insists on creating its own sources.list.d/google-chrome.list, so now I get an error of duplicate sources...
| |
| 13:31 | pmatulis has quit IRC | |
| 13:35 | <Lns> alkisg: ugh.. looks like google's 'experts' don't tend to work with debian much..?
| |
| 13:35 | <alkisg> Yeah, they assume that the user downloads the .deb from their site, and installs it without using a repository
| |
| 13:36 | So now I'll need an extra workaround to remove their repository from sources.list :( @#(*@#

| |
| 13:46 | (or something like that)
| |
| 13:50 | <anivair> for the record, after af ew hours of running it seems like the pasuspender flag has fixed the sound glitches I had. Since I only need sound for the phone, is there a way to make that universal, or should I just load all my instances of twinkle with that flag set?
| |
| 13:51 | I'm not sure exactly how pasuspender works, so I don't know if there's a way to expand it for ease or not
| |
| 13:54 | <Gadi> anivair: pasuspender isnt a flag, it is a program
| |
| 13:54 | so, just wrap your calls to twinkle in it
| |
| 13:55 | or, if you like, modify the .desktop file for twinkle
| |
| 13:55 | in /usr/share/applications/
| |
| 13:55 | or /opt/ltsp/i386/usr/share/applications
| |
| 13:55 | if local app
| |
| 13:55 | alkisg: strange that you get that message - as I dont
| |
| 13:56 | alkisg: but, to make you feel better, I'll go back to using echo
| |
| 13:56 | <anivair> I am doing that, I just didn't know if I could run it globally so as not to have to do it for each intance (or of I could modify my existing sound setup to accomplish the same thing)
| |
| 13:56 | <alkisg> Gadi: I think I got splash but not quiet, what do you have?
| |
| 13:56 | <anivair> for now I'll just wrap in it, but I'll look into more drastic options later when I have a tsting box to play with
| |
| 13:56 | <thunsucker> what are your thoughts about installing vbox tools in the chroot
| |
| 13:56 | <alkisg> Gadi: or include the initramfs functions...
| |
| 13:56 | <Gadi> alkisg: ah, without quiet...
| |
| 13:56 | <alkisg> Gadi: I think that would be best
| |
| 13:56 | <Gadi> ill go back to echo...
| |
| 13:56 | :)
| |
| 13:56 | just easier
| |
| 13:56 | <alkisg> Heh, coward :P
| |
| 13:58 | Yey! With the SSH_FOLLOW_SYMLINKS=false change, chrome, googleearth and wine work fine :)

| 19:10 | <vagrantc> all the applications available on the server are available, because you're actually running your applications on the server, and merely displaying them to the thin client.
| |
| 19:11 | <AndyGraybeal> okay interesting
| |
| 19:11 | i could swear i never put gimp on here
| |
| 19:11 | <vagrantc> might have come with the default install
| |
| 19:11 | <AndyGraybeal> ok
| |
| 19:12 | okay anyway -i'm not gonna think too hard about all of it - this is amazing.

| 19:36 | <sbalneav> AndyGraybeal: congrats
| |
| 19:40 | <AndyGraybeal> :)
| |
| 19:40 | thank you sbalneav
| |
| 19:41 | <sbalneav> The first time I ever got LTSP booting was back in November or December of 1999
| |
| 19:41 | I was so thrilled with it, I became a developer
| |
| 19:42 | <AndyGraybeal> that's pretty cool. 1999... i, what.. just turned... 19?
| |
| 19:42 | <sbalneav> and have been one for over 10 years now
| |
| 19:42 | <AndyGraybeal> nice
| |
| 19:42 | yea.. i was evil.. i was doing citrix back then
| |
| 19:43 | like when i was 19/20ish.. i worked for some place .. university.. but the spot i got was windows based... completley awful
| |
| 19:44 | <sbalneav> I'm the sysadmin for Legal Aid Manitoba.
| |
| 19:44 | <AndyGraybeal> i tried to learn linux as much as i could. i had played with bsd and linux prior, but could never get a job in it... so eventually i quit that job.. and i've dedicated myself to learning as much as i can about linux
| |
| 19:44 | <sbalneav> We're a Linu shop
| |
| 19:44 | 185 desktops, all running LTSP
| |
| 19:44 | I eat my own dogfood :)
| |
| 19:44 | <AndyGraybeal> nice. i co-own a restaurant; and a couple of us are learning how to turn this place into a linux shop.
| |
| 19:44 | lols
| |
| 19:44 | hey um.. your server, is it clustered?
| |
| 19:45 | because i'm thinking about if this server fails, it's my single point of failure...
| |
| 19:45 | <sbalneav> No, I just buy big servers, and hang 30-40 users off of them
| |
| 19:45 | <AndyGraybeal> and if i could figure out how to cluster for redundancy.. it might be useful
| |
| 19:45 | <sbalneav> stgabers been leading the charge on the clustering stuff
| |
| 19:45 | that's one of the cool things about free software.
| |
| 19:45 | <AndyGraybeal> your nicks look very similar... i need to get more familiar with the people in here.
| |
| 19:45 | <sbalneav> Ooops kids here
| |
| 19:46 | <AndyGraybeal> nice yuo got kids?
| |
| 19:46 | <sbalneav> yep
| |
| 19:46 | back on in a bit
| |
| 19:47 | <AndyGraybeal> nice, i'm working on it. yea thank you for talking.
| |
| 19:47 | oh.. is there a way i can 'detach' from my client and come back to it... with all my apps running (like screen or tmux?)

| |
