| 06:09 | <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

| 07:23 | <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
| |
| 07:28 | rac_ 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 | |

| 19:11 | <komunista> 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?
| |
| 19:55 | professor_ has joined IRC (professor_!c907012d@gateway/web/freenode/ip.201.7.1.45) | |

| 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
