stgraber: new ldm release in unstable ^, it's a bug fixing release for thin clients with LDM_DIRECTX=True, you may want to sync that in Wily
02:32
(although syncing ltsp is waaaay more significant, LTSP in Wily is completely broken now...)

<tootai>
Hello
07:48
Alkis Georgopoulos ask me to connect to this channel as I face a connection problem with Ubuntu 14.04.3 and LTSP from ts.sch.gr ppa
07:49
Client is a Raspberry Pi with BerryTerminal. Connection fail with
07:49
Oct 8 19:11:25 TOO-LTSP x-session-manager[2980]: WARNING: software acceleration check failed: Child process exited with code 1 Oct 8 19:11:25 TOO-LTSP x-session-manager[2980]: CRITICAL: We failed, but the fail whale is dead. Sorry....
07:49
<alkisg>
Hello tootai
07:49
The client doesn't have a new ltsp version then, right?
07:50
<tootai>
It should, should I send you the ltsp-info output ?
07:50
<alkisg>
I saw it in the mail, but it didn't report anything about armhf
07:50
Doesn't rpi use armhf?
07:51
You have an i386 chroot, but it's not the one you're using with the rpi
07:51
Right?
07:51
<tootai>
Remember, it's BerryTerminal, not a raspbian or other Pi distribution
07:52
<alkisg>
I don't know berryterminal. If it's rpi, it's arm, not i386
07:52
<tootai>
Anyway, the problem lies on gnome-session manager and x-session-manager: usin xfce4-session-manager make thinks working like expected
07:52
<alkisg>
You can't run i386 software in an arm processor
07:52
If you try with an updated ltsp, it should work
07:52
But you have an old ltsp in your arm chroot
07:53
<tootai>
so chrott && apt-get update && apt-get dist-upgrade, right ?
07:53
<alkisg>
No
07:53
You need a repository with an up to date ltsp
07:53
Ubuntu PPAs don't have software for ARM devices
07:53
I don't know where you can find an updated ltsp for arm
07:54
If you try with an i386 client it should work
07:54
It won't work with rpi until you find a newer ltsp for that
07:56
A new LDM has just been released in Debian, it should be available in the debian repositories in 10 days
07:57
A new LTSP will probably be released in a few days in Debian as well
07:57tootai2 has joined IRC (tootai2!~dash@keewi.tootai.net)
07:58
<tootai2>
alkisg, sorry, the web client not being friendly, I had to switch to XChat
07:58
<alkisg>
See irclogs.ltsp.org in case you missed something
08:00
<tootai2>
alkisg: as using xfce4-session-manager is OK, problem isn't connected to arm from Pi, but really on [x|gnome]-session-manager
08:01
<alkisg>
tootai2, so you think that when I saw the bug in the code and I fixed and I tested it I didn't know what I was doing and you are right now?
08:01
Cool
08:01
tootai2: read the fix: http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ldm-trunk/revision/1577
08:01tootai has left IRC (tootai!4ee67156@gateway/web/freenode/ip.78.230.113.86, Ping timeout: 246 seconds)
08:02
<tootai2>
No, you know what you do, I know. My question is why by just changing the session-manager make things work
08:02
<alkisg>
Because one is using 3d and the other isn't
08:06
<tootai2>
if I adapt the script with the fix it should work ?
08:06
<alkisg>
There are other fixes from the ltsp side, so probably no
08:06
there's ldm code and ltsp code, in another site
08:06
!ltsp-trunk
08:06
<ltsp>
ltsp-trunk: The LTSP code is at https://code.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk
08:09
<alkisg>
You can try if you like, I don't remember exactly, there's one possibility it will work...
08:19
> These, along with r2646 from ltsp-client, make Unity work for both thin and fat clients in Ubuntu 14.04, and possibly fix other DE issues as well.
08:19
So you need r2646 from ltsp as well
08:20
<tootai2>
the http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ldm-trunk/revision/1577 is already applied in my X50-generave-env
08:20
<alkisg>
Where, in the rpi or in the i386 chroot?
08:20
I think you're missing a step there
08:21
<tootai2>
i386 chroot
08:21
<alkisg>
The PIs don't use the i386 chroot at all
08:21
So you can delete it completely
08:21
You have an ARM chroot somewhere, maybe even in the SD cards
08:21
That is what needs to be updated
08:24gvy has joined IRC (gvy!~mike@altlinux/developer/mike)

<tootai2>
alkisg, with berryterminal which is a thin client, all is done by the server. It's just a terminal
08:26
<alkisg>
tootai2: thank you for explaining this to me, I'll change the code accordingly :)
08:27
tootai2: terminals have code
08:27
I write a part of that code, it's called ltsp
08:27
And it needs to be updated *before* it connects to the server
08:27
The ltsp and ldm scripts that are *in the sd card* need to be updated
08:28
Put the sd card in your PC and run ls, you'll see the files
08:28
<tootai2>
OK, sorry :-(
08:52
<alkisg>
tootai2: did you find where you have your chroot? Is it in your SD cards? Or have you transferred it in /opt/ltsp/images?

11:52work_alkisg is now known as alkisg
11:52
<alkisg>
tootai: does the sd card have one partition or two?
11:53
And what files do you have in the server's /opt/ltsp/images?
11:53
And what dirs in /var/lib/tftpboot/ltsp?
11:58
Your chroot is somewhere, you just need to find it
11:59
The operating system for the client to boot, ltsp-client to configure it, the login screen ldm, all those are in the chroot (and it's not the i386 chroot)
11:59
This is what you need to find and update
12:02
The server programs only run after you login, all the things that you see before that are in the chroot
12:14
<tootai>
alkisg, my sdcard has 2 partitions: berryboot and another of 66 MB
12:15
beerryboot has 4 dir: /data /images /shared /tmp
12:16
in that dir I have 5 dirs: /etc /root /tmp /usr /var
12:17schlady has left IRC (schlady!~schlady@141-53-215-125.ip.uni-greifswald.de, Remote host closed the connection)
12:18
<tootai>
sorry, one phase is missing before the 5 dirs: in /data I have dir /LTSP_thinclient_BerryTeminal.img and one file /default
12:18
<alkisg>
So there it is
12:18
How big is it?
12:18
`du -sh file` tells you the size
12:25
<tootai>
dh@deex:/media/dh/berryboot/data$ sudo du -sh LTSP_thinclient_BerryTerminal.img/
12:25
112K LTSP_thinclient_BerryTerminal.img/
12:25
<alkisg>
K or M?
12:25
<tootai>
K
12:25
<alkisg>
That's not it then
12:25
Maybe in /images?
12:26
tootai: is that SD card now inserted on your server?
12:26
If so, do this for remote support so that we finish this faster:
12:26
!vnc-dide
12:26
<ltsp>
vnc-dide: To share your screen with me, run this: sudo apt-get --yes install x11vnc; x11vnc -connect srv1-dide.ioa.sch.gr - this is a reverse connection, it doesn't need port forwarding etc.
12:28
<tootai>
in /images I have dh@deex:/media/dh/berryboot/images$ sudo du -sh LTSP_thinclient_BerryTerminal.img
12:28
23M LTSP_thinclient_BerryTerminal.img
12:28
dh@deex:/media/dh/berryboot/images$
12:29
SD card is connected to my laptop using a card reader
12:31
x11vnc is launhed
12:31
*launched
12:35
I am
12:35
<alkisg>
tootai: did you see the contents of this image?
12:35
<tootai>
yes
12:35
<alkisg>
This has a very old version of ltsp
12:35
That's what you need to update
12:36
But it will be difficult as it seems that berry terminal uses a bundled ltsp, not one you can update
12:36
So if berryterminal doesn't ship a newer version, you need to install ltsp in a different way, not with berry terminal
12:37
<tootai>
I understand. I will see with raspbian then
12:37
<alkisg>
let me unmount the img for you
12:37
get me to the shell
12:37
Close vnc with ctrl+C
12:38
<tootai>
done
12:39
many thanks for your support, I will tthen try another way
12:39
<alkisg>
You're welcome
