<rac_>
ltsp thin client how to accelerate Graphic in the LTSP client, because the client LTSP sometimes slow respone
06:10
anyone can help ?
06:12
<sebd>
rac_: in /srv/tftp/lts.conf, see whether you have LDM_DIRECTX=True
06:17
<vagrantc>
rac_: if the clients can handle it, try fatclients
06:17
!fatclient
06:17
<ltsp>
I do not know about 'fatclient', but I do know about these similar topics: 'fatclients', 'fatclient-printers'
06:17
<vagrantc>
!fatclients | echo rac_
06:17
<ltsp>
rac_ fatclients: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients
06:17
<vagrantc>
!ltsp-pnp | echo rac_
06:17
<ltsp>
rac_ ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp

<sebd>
Some of my users complain that they cannot halt an LTSP client when I performed an update of the client filesystem NBD image: their computer is rebooted after displaying a message saying the OS was updated. Should this be reported as a bug ? Is there a workaround ?
07:24
(I have not investigated yet)
07:26
<alkisg>
sebd: there is a check in ldm that reboots the client when ltsp-update-image was ran *after* the client was booted
07:26
This should only happen once per client, until they all get booted with the new image
07:26
If it happens again after that one time, then it would be a bug
07:28rac_ has left IRC (rac_!71148af6@gateway/web/freenode/ip.113.20.138.246, Ping timeout: 250 seconds)
07:28
<sebd>
alkisg: that is it. And it works fine.
07:30
But some of my users keep their computer up all day. Then they close their session and want to switch the computer off. And they cannot. They have to wait until the computer has restarted.
07:30
I have no easy solution for this minor issue
07:30
<vagrantc>
oh.
07:30
<alkisg>
sebd: the can press cancel
07:31
And then shutdown
07:31
<sebd>
ah ok there is a cancel button (did not see it myself)
07:31
I tell them that
07:31
thank you
07:31
<alkisg>
It's also possible to put a shutdown shortcut for them on the menus or the desktop
07:31
<vagrantc>
or set an x property to shutdown on logout ... which is supported out of the box on precisely two desktop environments that i know of :)
07:31
<alkisg>
There are example .desktop files in ltsp for that
07:32
vagrantc: which is the second one?
07:32
I know of lxde...
07:32
<vagrantc>
alkisg: i think lxqt also
07:32
<alkisg>
Meh, it's one and the same :D
07:32
<vagrantc>
which is arguable the sucessor ...
07:33
<alkisg>
Let's send a patch for mate as well... sbalneav? :P)
07:33
<sebd>
Ah, here we have been using XFCE and I could not find a way to switch the CLIENT computer off (thin clients tend to try and halt the SERVER)
07:33
<vagrantc>
or maybe razorqt or soemthing implemented support as well ... which got merged into lxqt
07:33
yeah, getting support in MATE would be nice.
07:33
XFCE would be good as well
07:33
of course, all of them would be ideal :)
07:34
<alkisg>
It would be ideal if the desktop session returned a sensible exit code to the display manager... not some xprop...
07:34
E.g. 0 = all ok, 1 = reboot, 2 = shutdown, stuff like that
07:34
<vagrantc>
yeah
07:34
meanwhile, back on planet eart...
07:34
<alkisg>
But it's difficult to set cross-de standards
07:35
:D
07:35
Haha true
07:35
<vagrantc>
or if you set them, it's difficult for the standards not to change all the time
07:35
<alkisg>
https://xkcd.com/927/
07:36* vagrantc sure finds a change of timezone interesting with regards to irc
07:36
<vagrantc>
it's like parallel universes with some of the same people
07:36
<alkisg>
And wrt morning wake ups, from what I read in #debconf... :D
07:56
<vagrantc>
sbalneav: now would be a good time to try to upload the lightdm-webkit* stuff too, as i can nudge people who'll move it through the new package process faster
07:57* vagrantc will probably have to recreate the packaging, but it wasn't too difficult

Does anyone know of a comprehensive, working and updated tutorial for LTSP start to finish on an already established desktop? We use a windows server for DHCP. It seems that every resource is outdated or non-complete.

hi all
19:12
alkisg: If you remmeber our discuss week ago, I tried the debian testing for chroot on the wheezy server
19:13
but the ltsp-build-chroot ends with missing linux-image-486
19:13
when I manually install linux-image-686 in chroot and build new NBD image, the clients get kernel panic
19:15
I see the broken symlink of the nbi.img, I don't k now if it is related...
19:15
some idea to I have check, please?
19:49
<alkisg>
komunista: nbi.img is not used anymore at all
19:49
It was used before 2009 for etherboot clients
19:50
What is the message of the kernel panic?

20:07
<komunista>
alkisg: I am not near the thin client now, but I remember something as "cpu0 not found", followed some other lines
20:08
<alkisg>
komunista: is the kernel compatible with the client cpu?
20:08
<komunista>
I am not sure, it is 686-pae
20:08
<alkisg>
Do you remember the client cpu model?
20:08
Is it quite old?
20:08
<komunista>
but the panic happens on old clint and on new Intel NUC too
20:09
<alkisg>
The new intel nuc also says cpu0 not found?
20:09
<komunista>
yes, but it tell cpu1
20:10
<alkisg>
What are the contents of /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default? Can you put those to pastebin?
20:10
<komunista>
good question
20:10
I found that the pxelinux.cfg/default fil was not updated on chroot install
20:11
then I move it and I did symlink to ltsp (in the same dir)
20:11
*I move the old one...
20:12
<alkisg>
Erm this sounds like too much customized :)
20:12
Do you have access to the server currently?
20:13
<komunista>
see here https://paste.fedoraproject.org/386039/14477214/
20:13
the contents of the tftp pxe dir, see the dates
20:13
the default.bak is the old backup
20:13
and you can see, the new default was not created
20:14
<alkisg>
You can see the contents with "cat", not with "ls"
20:14
We need the file contents, not the dir listing
20:14
cat default
20:14
<komunista>
sure, I know, I want to show the dir's content
20:14
<alkisg>
OK
20:15
The default file is generated by ltsp-update-kernels
20:15
(symlink)
20:15
<komunista>
there is not the default file, and the default.bak has the kernels from previous old chroot
20:15
<alkisg>
OK, but all those don't move the troubleshooting forward
20:15
If you have access to the server, it would be much faster to share you screen with me
20:16
!vnc-dide
20:16
<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.
20:20
<komunista>
do you mean to run x11vnc ont the LTSP server?
20:20
or on my local machine?
20:21
<alkisg>
Whatever has xorg running
20:21
If you use ssh to connect to the server, then you can run that on your local machine
20:21
If you have xorg access to the server, you can run it directly there
20:21
If you only have text access with no xorg, there's another method with socat+screen...
20:21
<komunista>
I have some problem with X11Forwrading on server:
20:21
Warning: untrusted X11 forwarding setup failed: xauth key data not generated
20:22
<alkisg>
Why would you need forwarding? Are you trying ssh -X?
20:25
<komunista>
ssh -WHY solved problem
20:25
ssh -Y
20:25
eh, autocorrection
20:27
but the vnc server died
20:29
<alkisg>
There's not much point in ssh'ing and then running vnc remotely for your *local* server...
20:30
Just run it locally
20:31
<komunista>
compiling VNC will take some time for my local machine (I am not on Debian)
20:32
<alkisg>
!socat
20:32
<ltsp>
socat: One way to share a console with a remote person is: [local pc] forward port 5500; apt-get install socat; socat tcp-listen:5500,keepalive=1 stdio,raw,echo=0 [remote pc] apt-get install socat screen; socat SYSTEM:"sleep 1; exec screen -xRR ra",pty,stderr tcp:REMOTE-IP:5500 & screen -l -S ra
20:32
<alkisg>
...that's the text only variant...
20:32
but time for me to go... maybe some other day
20:37
<komunista>
OK, I run vnc localy
20:39
<alkisg>
http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/revision/2733
20:40
<komunista>
OK
20:40
build the chroo from fresh now
20:40
<alkisg>
komunista: you don't have a kernel in the chroot, so it won't boot that way
20:40
OK, build a new chroot, it should have the 686 kernel
20:41
<komunista>
it is fresh install, form some ten mins ago
20:41
<alkisg>
komunista: don't type things in the terminal
20:41
I can't monitor both the irc chat and the terminal chat
20:45
<komunista>
we can continue tomorrow...
20:47
<alkisg>
komunista: it's ok for nfs, but nfs doesn't work in stretch
20:48
You need to run ltsp-update-image to create an nbd image
20:48
<komunista>
I don't use NFS
20:48
<alkisg>
You don't have nbd configured though
20:48
Anyway, some other time... bb for now
20:48
Try ltsp-update-image
20:49
<komunista>
done
20:50
OK, see later, regards
