<Keaton>
Hey, #ltsp, I've got another Ubuntu question. Anyone out there know a way to disable some of the services that come up on login that take up big ol' gobs of RAM, like tracker, bluetooth daemon, etc.? Thus far I haven't found anything but the 'Session' preferences GUI, but I don't know where it writes it's settings to or how to set them globally.
10:39
<ogra>
System-Admin->Services ...
10:40
<Keaton>
Oh. wow, now I feel like a jackass. :P
10:40
<ogra>
and uninstall tracker completely ... its just evil in multiuser envs

11:46* Lns wishes he knew about calendarserver before installing webdav/apache =p
11:46twinprism has joined #ltsp
11:46
<Nubae>
why, whats calendar server?
11:49
<Lns>
Nubae: it's apple's open-source caldav server
11:49
<Nubae>
ah
11:49
<Lns>
i'm thinking not to use it actually, it seems more complex than what i want
11:50
supposed to be better than webdav though, as it only transfers single events/items from an ics
11:50
instead of the whole thing
11:50
i got a corrupted calendar because i think i shut down my system with sunbird still open in the middle of a sync...
11:51
kinda lame, calendarserver requires a filesystem with extended attributes turned on
11:51nicoAMG has joined #ltsp

<Lns>
how goes it Nubae ?
11:54
<Nubae>
yeah not too bad
11:54
been real busy though
11:54
had to leave a lot of edubuntu stuff on the back burner...
12:05
<Lns>
i hear you
12:06
the nice thing is, we usually all stick around so when we have downtime we can all pitch in =)
12:06
<Nubae>
do u know if domino (lotus) server works on ltsp?
12:06
I'd imagine it should...
12:06
<Lns>
i would imagine
12:07
my brother works a lot w/domino
12:07
<Nubae>
yeah this software company wants me to put together a package small business server, based on ltsp and lotus
12:08
it seems like a nice alternative to MS
12:16spectra has joined #ltsp
12:19
<epsas>
so... running 32 bit terminals on a 64bit server is possible?
12:20
<NeonLicht>
if you have plenty of RAM, yes
12:20
mainly if users will run browsers
12:20Lumiere__ is now known as Lumiere

_UsUrPeR_: I received your company's 1520 client today. It seems really awesome.
12:44
<ogra>
is that the atom based one ?
12:52
<warren>
ogra: yes
12:55elisboa_ has quit IRC
12:55
<stgraber>
warren: yeah, the 1520 rocks, just a small issue with LVDS appearing when there's none but that's easily fixed
12:55
(that's fixed in Ubuntu so the 1520 works out of the box in Jaunty)
12:56
<warren>
stgraber: LVDS appearing when there's none means?
12:56
stgraber: what did you do to fix it?
12:56elisboa has joined #ltsp
12:57
<stgraber>
if you do a xrandr call, you see a LVDS output because the video card is a laptop one (and at least in Ubuntu X forces a LVDS output for the mobile chipsets)
12:58
warren: http://paste.ubuntu.com/133799/
12:59
<warren>
stgraber: why not push this to ltsp usptream?
13:00
<stgraber>
warren: I only push upstream what I know to be broken on all distro, I didn't test that thin client with all distros
13:00
<warren>
stgraber: ok, how do i test this?
13:00
stgraber: plug which video out into what?
13:01
<stgraber>
usually if you're unable to change your resolution it's because of that LVDS output
13:02
warren: with that fix the LVDS output completely disappears from xrandr
13:02
<warren>
stgraber: ok testing
13:02
<ltsppbot>
"stgraber" pasted "expected xrandr output on 1520" (14 lines) at http://pastebot.ltsp.org/287
13:04
<warren>
stgraber: could you post this workaround to the upstream list so it is on record?
13:04
stgraber: our X guys are looking at this box now, so maybe they can come up with a real fix
13:05
<stgraber>
warren: issue being that the ship is just 100% identical on netbooks (EEE 1000H for example) and that box, Ubuntu's X guys haven't found an easy way to detect it and a bug upstream was rejected IIRC
13:05
warren: I'll post on the mailinglist and attach the 3 workarounds I added for Ubuntu
13:05
<warren>
stgraber: thanks, that's perfect
13:06
stgraber: please also include bad xrandr and expected?
13:07
<stgraber>
if I can find the hardware :) some where reported by users, some others by customers and I only have a few at the office. I'll at least add a description of what it's fixing so if someone see the same bug he can uses the script (that someone can be a distro maintainer :))

13:16
<epsas>
i am installing debian lenny for an ltsp server
13:16
<vagrantc>
epsas: i just got backports of ltsp for lenny readied the other day :)
13:16
<NeonLicht>
good for you, you coudn't choose better, epsas :-)
13:17
<ogra>
sure, he could have choosen ubuntu :)
13:17

brb
13:17warren has quit IRC
13:18

and we obviously managed to scare off fedora
13:18
<ogra>
heh
13:18
he is quickly gone to talk to his marketing dept. ;)
13:18
<epsas>
i evaluated fedora out of respect for Mr Togami =)
13:19
<NeonLicht>
I'm trying to understand pulseaudio and get the sound working on my thin clients
13:19
<ogra>
there is not much to understand
13:20
does sound and volume control not work for you ?
13:20
<NeonLicht>
ogra, well, I need to understand how to get it running XDD
13:20
<ogra>
you shouldnt have to do anything
13:20
i.e. it should work out of the box
13:21
at least as long as your soundcard is supported by the kernel
13:21
s/kernel/alsa driver/
13:21
<NeonLicht>
well it does not
13:21
is it a sound card needed on the server?
13:22
or just on the thin clients?
13:22
<ogra>
only on the clients
13:22
<NeonLicht>
the thin clients do have one, of cours, but the server most probably does not
13:22
<ogra>
in ubuntu we have an Xsession.d script that sets up a virtual alsa device, not sure any other distro uses that
13:22
<NeonLicht>
it is a 1U rackable box
13:23
<vagrantc>
NeonLicht:
13:23
<Lns>
NeonLicht: you only need a soundcard in the server if you're running MS Terminal Server
13:23
<vagrantc>
!release
13:23
<ltspbot>
vagrantc: "release" is please mention the linux distro and release you're using :)
13:23
<ogra>
but with that connecting to the pulse server on the client it should just work as long as your driver works
13:23
<NeonLicht>
I see
13:24
I get mplayer complaining about being not able to find card '0'
13:24
<ogra>
how do you run mpolayer ?
13:24
<NeonLicht>
and then [AO OSS] audio_setup: Can't open audio device /dev/dsp: No such file or directory
13:24
<ogra>
indeed
13:24
you need the right -ao setting for mplayer
13:24
<NeonLicht>
ogra, I run mplayer from the command line, of course, as I run everything :-)
13:25
<ogra>
esd or pulse or if you run ubuntu alsa should all work
13:26
<vagrantc>
NeonLicht: what distro?
13:27
<NeonLicht>
Debian GNU/Linux, vagrantc, of course :-)
13:27
-ao esd works!
13:27
<ogra>
sure
13:27
<NeonLicht>
thanks a lot, ogra, vagrantc
13:27
<ogra>
pulse emulates esd
13:27
pulse should work as well
13:27
not sure about alsa on debian
13:27
<vagrantc>
NeonLicht: /usr/share/doc/ltsp-server/README.Debian.sound
13:27
<NeonLicht>
neither pulse nor alsa do
13:27
<ogra>
i doubt vargrant likes my hack :)
13:28
<NeonLicht>
thanks, vagrantc!
13:28
<vagrantc>
NeonLicht: it may need some updating, but it gets most applications to work out of the box.
13:28
some unusual apps definitely still have problems.
13:28* vagrantc returns to work
13:29
<NeonLicht>
going to try ogg123... I need some music! haha
13:31
ogg123 works both with pulse and esd
13:32
it does not with alsa
13:33
<ogra>
you need the virtual alsa device for that
13:33staffencasa has joined #ltsp
13:34
<NeonLicht>
it shpuld be convenient for me to have it then, I guess, since most programs seem to use alsa as their default
13:35Remaille has joined #ltsp

<ogra>
NeonLicht, http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/annotate/head%3A/server//80_ltsp-sound
13:40
thats what we have in /etc/X11/Xsession.d in ubuntu
13:42
<NeonLicht>
is that related in any way to the virtual alsa device you refered to b4?
13:42Remaille has quit IRC
13:43
<vagrantc>
ogra: that script doesn't work at all on debian
13:43
ogra: it requires patches to alsa-foo
13:44
NeonLicht: the instructions for setting up the alsa -> pulse stuff are in /usr/share/doc/ltsp-server/README.Debian.sound
13:44
<NeonLicht>
the more I know Ubuntu, the more I like Debian :-)
13:44
ok, vagrantc, thank you!
13:44* vagrantc values the contributions of both Debian and Ubuntu, but often grumbles about Ubuntu
13:44twinprism has quit IRC
13:47
<NeonLicht>
great, vagrantc, mplayer and ogg123 both run now with alsa, ie, wo having to instruct them what to use :-)
13:47twinprism has joined #ltsp
13:47
<NeonLicht>
thanks a lot, ogra, vagrantc, your help has been very heplful!
13:47
<vagrantc>
sure beats my help being harmful :)
13:48
<NeonLicht>
haha
13:51
<ogra>
vagrantc, that comes from upstream
13:51
no idea why debian rips out the asoundconf script
13:52
<NeonLicht>
I don't know the asoundconf script, but if Debian decides to trash it I belive it must sucks a lot XDDD
13:53
<vagrantc>
ogra: the set-pulseaudio and unset-pulseaudio commands were implemented as ubuntu patches, last i looked.
13:54
<NeonLicht>
(just pecking XDD)
13:55
<vagrantc>
ogra: would be really nice to get those features upstream
13:57
<NeonLicht>
well, I'm leaving for home now, very happy for having the sound matter fixed, again thank you!

Does your server have to run a DHCP server to use LTSP, or can you have a router do it?

Eviltechie: typically, your server has to run a DHCP server. But if you have a programmable router that can send a boot filename etc, you can also use it. Another option is to use a proxydhcp. And another one is to use gpxe.
16:52BigBanHammah has joined #ltsp
16:53
<Eviltechie>
alkisg: Which one is easiest?
16:53
<alkisg>
The first one, to install dhcp3-server in your dhcp server.
16:53
*ltsp server
16:54FlyOnThe1all has joined #ltsp
16:54warren has left #ltsp
16:54
<Eviltechie>
The thing is, I only have one network card, and a home router. I tried setting it up in vmware, but it keeps locking up during the install.
16:56
<alkisg>
Where do you want to install ltsp, in the real box or in vmware?
16:56synchris_odium has joined #ltsp
16:56
<alkisg>
You can install ltsp with one NIC, that's not a problem...
16:57
<Eviltechie>
I just want something to play around with, not for a production enviroment.
16:58
<alkisg>
Well, you can install ltsp server in your real box, and use vmware as a thin client
16:58
Or you can install both the server and a client in vmware; again no problem
16:58
<Eviltechie>
I was originally trying to install both in vmware, but the install kept hanging at 50%
16:59
<alkisg>
Which distro?
16:59
<Eviltechie>
Ubuntu
16:59
<alkisg>
Alternate cd?
16:59
<Eviltechie>
Yes
16:59
<alkisg>
It shouldn't hang because of 1 or 2 nics; something else may be the problem
16:59
<Eviltechie>
It was giving a RSOD.
16:59
<alkisg>
But you may tell vmware that you want 2 nics...
17:00
<Eviltechie>
Yes, but I think that the problem is that my vm dosen't know what NIC is which. They show up as exactly the same.
17:01BigBanHammah is now known as o[{^_^}]o
17:01
<alkisg>
Why don't you try with vbox? Networking is much easier with it.
17:02
<Eviltechie>
Virtual box?
17:02
<alkisg>
Yes, 2.1.x uses packet injection and works without tun/tap devices
17:02
You don't have to do anything, it just works :)
17:03synchris has quit IRC
17:03
<Eviltechie>
I'll give vmware one last shot. If that fails, I'll go for vbox
17:06
<alkisg>
Eviltechie: you may also try `sudo apt-get install ltsp-server-standalone` in your real box, followed by `sudo ltsp-build-client`.
17:06
<Eviltechie>
I tried that, but I noticed that it came with dhcp.
17:06
<alkisg>
Yes, but you do want dhcp to properly test it...
17:07
If you don't want dhcp, you do `sudo apt-get install ltsp-server`
17:07
<Eviltechie>
I absolutrly cannot mess my home network.
17:07
<alkisg>
Then you may install ltsp-server, and test with a gpxe boot disk in a vmware client: https://help.ubuntu.com/community/UbuntuLTSP/grubgpxe

17:24
epsas: i hope to have them at backports.org someday, but they're indefinitely stalled in migrating to testing, so i can't get an upload to backports.org until they make it there.

known issues shouldn't be issues, but and i'm not sure users need to be added to the audio group ..

Tells me it's going to use /etc/nxserver/nxacl to determine settings or if the user should be there or not, but doesn't actually run it.

I don't know how to dynamically allocate connections for VNC users.

vagrantc, hi, i tested rdesktop -s shell, works, but slight different than we expect
23:56
-s kde4, -s icewm, -s gnome, etc works, there is startwm.sh script that xrdp uses to launch session properly with /path/to/Xsession startwm.sh
23:59
<vagrantc>
cyberorg: huh. so why didn't it work with your initial patch?
23:59
but very nice if xrdp properly handles Xsession ...
23:59
<cyberorg>
vagrantc, what does ldm.session return?
23:59
<vagrantc>
saves us some hassle.
