Hello everyone. I'm trying to set up LTSP to work with HP T5520 thin clients that have a VIA "VT8623 [Apollo CLE266] integrated CastleRock graphics [1106:3122]"
15:21
The problem is that the client hangs after a while since logging in to the X session on Ubuntu 12.04.
15:22
The output of `lspci -k` is "Kernel modules: vt8623fb, viafb"
15:22
I've googled this chip and it is common to have issues with it on linux.
15:23
What I've found is that it was working OK on an ancient Ubuntu version 7.04.
15:24alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg)
15:24
<ncom0pl>
And now I'm trying to either build a 7.04 chroot or maybe use some oher driver on the current release.
15:25
But I get errors when building even not-so-ancient release 10.04...
15:26
There is a bug report related to that issue here: https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/1048699
15:27
<alkisg>
ncom0pl: is 7.04 the last version that's working ok? 8.04 would be a much better candidate, with it being an LTS release...
15:28
<ncom0pl>
I'm not sure, I havent tested but what I've found googling around is that 7.04 was OK, and then with 7.10 upwards it was getting worse.
15:29
<alkisg>
OK... see my reply to the link you pasted for what went wrong in that bug report
15:29
<ncom0pl>
Yeah, I just noticed it's your reply.
15:30
So it's preety much the only way to build the chroot using an older release?
15:30
And then transfer it to my 12.04.
15:31
<alkisg>
Nope, just don't use NBD, use NFS
15:33
You could also try a debian squeeze chroot, it's a bit old but still supported and it might work fine
15:34
<ncom0pl>
Also, when I'm trying to build 10.04 I get the dpkg error, but when I try to build any older release, it just can't find the release...
15:34
I'll see if squeeze builds fine.
15:37
Hmm, in order to build client with a release specified in --dist, I have to add the release repos to my server's sources.list, is that correct?
15:54
No, that's incorrect, but I've managed to make it work with --mirror.
15:54andygraybeal has joined IRC (andygraybeal!~andy@h23.205.213.151.dynamic.ip.windstream.net)
15:57
<alkisg>
ncom0pl: some older ubuntu releases are now only archived so their mirrors have changed, you need to google for the new mirrors
15:57
E.g. archive.ubuntu.com or something
15:58
The advantage with the squeeze chroot is that it's maintained a lot more, e.g. you can install a newer nbd version there, newer even than what 12.04 has
15:59
<ncom0pl>
Yeah, I just like Ubuntu because...well I'm lazy and it's a lot more easy to use out of the box so to speak, but debian always seems more stable.
15:59
Damn it, those errors again...
15:59
"chroot: failed to run command `locale-gen': No such file or directory"
16:00
<alkisg>
If you have a VM, download the 7.04 alternate CD, as it contains the packages to install AND build a chroot
16:01
It'll at least allow you to see if the client works fine, with the VM server
16:01
Before going through the necessary workarounds to match the old chroot with your newer versioned server...
16:03
<ncom0pl>
I'll definitely try that, I'm downloading the iso right now.
16:04
But in the meantime I'm trying to build squeeze, any help on that "chroot: failed to run command `locale-gen': No such file or directory" error?
16:06
<alkisg>
Is locale-gen available in your chroot?
16:06
ls /opt/ltsp/i386/usr/sbin/locale-gen
16:07
<ncom0pl>
The chroot that I'm building, right? 'Cause I also used --chroot squeeze-i386
16:07
<alkisg>
Yes, the one you're building
16:08
<ncom0pl>
Nope, "".
16:08
ls: cannot access /opt/ltsp/squeeze-i386/usr/sbin/locale-gen: No such file or directory
16:09
<alkisg>
cat /opt/ltsp/squeeze-i386/etc/issue
16:09
<ncom0pl>
Debian GNU/Linux 6.0 \n \l
16:10
<alkisg>
sudo chroot /opt/ltsp/squeeze-i386 dpkg -l
16:10
And pastebin that
16:12
Btw, you didn't use --copy-sources-list, right?
16:12
What was your ltsp-build-client command line?
16:13
<ncom0pl>
I didn't.
16:13
sudo ltsp-build-client --arch i386 --dist squeeze --chroot squeeze-i386 --mirror http://ftp.task.gda.pl/debian/
16:16
http://pastebin.com/kBUwXYyt
16:16
So should I use --copy-sources-list?
16:18
<alkisg>
No, no you shouldn't

Hey all, long time no chat =) My LTSP Term 1220 is experiencing this bug for a while now on Debian Jesse.. https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-openchrome/+bug/1097732 - anyone have a quick fix for this? I'm going to try 24-bit resolution but i'm running it on 100Mb/s link so it'll probably slow down like the OP.

hey alkisg =) actually, changing x_color_depth=24 worked and didn't really slow down (even with flash video =) ) Hope everyone in here is doing well! What's the status of good WMs for LTSP? I moved to KDE on my desktop and I know gnome3 is pretty unusable..any first contenders, or is it still up to xfce/lxde/etc?
18:14
<alkisg>
gnome-flashback, mate-desktop, xfce, lxde..

"E: Couldn't find package linux-image-386" while ltsp-build-client on andcient Ubuntu 7.04. Any ideas?
19:29
<alkisg>
ncom0pl: with the alternate cd, you boot with it, and press f4 in the initial isolinux screen, and select "install an ltsp server"
19:29
That uses the cd as the source, so that you don't need to locate the archive.ubuntu.com mirrors..
19:30
<ncom0pl>
Aahhh, okay, thanks :).
19:30
<lns>
ncom0pl, why are you using such an old version of Ubuntu?

I did ltsp-update-sshkeys

still get: pam_unix(sshd:auth): authentication failure
20:13
so ldm does not start

20:25
ncom0pl: the *alternate* cd, ok?
20:25
roottoo: ldm doesn't start because of authentication issues? or do you mean the user cannot login?
20:28
<ncom0pl>
alkisg: I did download an alternate cd, but there's video mode selection under F4 in the menu, strange.
20:29
<alkisg>
Maybe it's some other Fx key and I don't remember well? It's been years...
20:32
<ncom0pl>
Yeah, but F1 is help, F2 is Lang, F3 is Keymap, F4 VGA, F5 Accesibility, and F6 Normal/Expert mode
20:33
<alkisg>
ncom0pl: ah, is that the ubuntu or the edubuntu cd?
20:33* alkisg doesn't remember which one had it
20:34
<ncom0pl>
Right! Of course edubuntu had it, I even remember reading abut it...
20:34
But I downloaded ubuntu.
20:34
Thanks.
20:36
It's called "classroom server CD".

<thyyrr>
can someone tell me if I run a LTSP server on a notebook can I run a session within it? my use case would be a notebook connected to a tv via HDMI outputing a XBMC session and in other room a raspberry pi as a thin client. would it be possible or I need other route?
21:50
<ncom0pl>
Isn't RPi powerful enough to run XMBC on it's own?
21:51roottoo has left IRC (roottoo!~Arne@82-169-21-9.ip.telfort.nl, Remote host closed the connection)
21:52
<thyyrr>
for a small library yes. but as the library gets bigger there is too much lag. and I plan to get more raspberry pis for using in other rooms (serve the whole family) and even upgrade my server to a full desktop
21:57
<ncom0pl>
So you want to run a server on your notebook, and also a client connecting to it on the same notebook?
21:58
<thyyrr>
yes
21:59
<ncom0pl>
You could probably set up a VM on the notebook that would act as a client.
22:00
But I'm an LTSP noob myself, so there might be a better way of doing this.
22:01* alkisg uses DLNA to send his library directly on TVs... :)
22:02
<thyyrr>
Hummmm, Thanks anyway. I'll keep looking, but so far I have found nothing.
22:02
My TV does not support DLNA =/
22:02
<alkisg>
Streaming uncompressed HD content needs more than 1 gbps
22:02
Do you have 10 gpbs network at home? :)
22:02
Nope, so you need to send compressed video...
22:04* ncom0pl scratches his head
22:05
<ncom0pl>
alkisg: Do you think I can use a single NIC setup on Ubuntu 7.04?
22:05
<alkisg>
thyyrr: 1920×1080×30×32 = 1.990.656.000 => 2 gpbs to stream true hd at 30 fps
22:05
ncom0pl: sure
22:06
<thyyrr>
I don't plan to stream videos, music or anything to the RPi. The RPi client would be for webrowsing
22:06
<alkisg>
Why do you want to netboot it?
22:06
<ncom0pl>
Cause during the installation it said there were not enough interfaces, and pointed me to the dhcpd.conf to configure it manually.
22:06
<alkisg>
thyyrr: It can be done with ltsp, some people here have done it
22:07
ncom0pl: yup it's nothing hard you just edit that file
22:08
<ncom0pl>
Just wasn't sure if it was going to work with single NIC on an ancient version.
22:08
One way to find out :)>
22:08
<alkisg>
It's nothing critical, just a warning that dhcpd.conf needs to be edited
22:09
<thyyrr>
alkisg: because I'll use it to programming (in x86 and x64) sometimes and I don't know a way to test x86 programs on the RPi or if it will have the power to compile things smoothly
22:10
<alkisg>
thyyrr: netbooting is a different thing from remote desktop
22:10
You can have remote desktop with remote X, with x2go, with vnc etc, or remote console with ssh, screen etc etc
22:10
If you want to netboot it, sure, it can be done with ltsp
22:10
And it can support localapps/remoteapps (on the x86 server) etc
