Problem with X2GO session
by Piotr Mozdzynski 05 Mar '12

05 Mar '12

Hello. I am new to this list , sorry for starting from issues.. we are facing problems with X2go , it crashes X2GO session when we open the Office 2007 "quick access button" This does not occur on direct sessions , only when connected via X2GO. We found this article : http://www.codeweavers.com/support/tickets/browse/?ticket_id=845080; We disabled the registry in Wine , this helped and Office2007 is not crashing , but the buttons are missing and we cannot see hi-lighted text in MS-Word/Excel , several things are missing. Only what I can attach here is a line from syslog (X2go Server) : kernel: [84085.656572] x2goagent[16641]: segfault at 7f0b9dd61ff4 ip 00000000004d3650 sp 00007fff09b8aff8 error 4 in nxagent[400000+4fa000] Anyone had simmilar problems ? I remember before X2go was also crashing on some applications , but after few updates it doesn't anymore. Could not find anything more , any help to resolve this much appreciated. regards Piotr

Changing X2Go SSH configuration
by Ivan Hernandez 01 Mar '12

01 Mar '12

Hi list, I have been working with x2go to replace my old freenx/PXE Setup. As I use low end thinclients the cpu used for encryption is not that much powerful so I compiled hpn-ssh and made it work with the none cipher. On tests with scp it made a big difference making a file tranfer to go from 58%cpu and 8.5Mb/sec to 33%cpu and 11.6Mb/sec. So now I have to find a way to tell x2go client to use that ssh client instead of the default one, and with my options. But instead I see fixed options that I can't change like: ssh -x -a -oClearAllForwardings=yes -oServerAliveInterval=300 -oCipher=blowfish So... how can I change that?? Thanks in advance Ivan

Call logout script
by senrabdet＠aol.com 01 Mar '12

01 Mar '12

Hi All: Is there a way to call a logout script (i.e., one that is specific to each user upon ending a session)? In Ubuntu Server 10.4 we've tried various things including .bash_logout and /etc/gdm/PostSession/Default either performing a command or calling .bash_logout. The "/etc/gdm/PostSession/Default" works if we log in directly, so assume this has something to do with xsession(?) and hope there is a way in an x2go session where when the user logs out, a script gets called in the background. Thanks!

Re: [X2Go-User] X2goserver on Ubuntu 10.04.4 server...can't login.

I'm experiencing this error as well. i'll attach a log file from one of my login attempts. The attempt was without sound enabled, though. When sound is enabled, it seems that Pulseaudio gets stuck in a loop of some sort, repeating: Feb 27 08:02:07 fleten-01 pulseaudio[29396]: [pulseaudio] main.c: User-configured server at localhost:30002, refusing to start/autospawn. about once every three seconds. I havent tried to replicate this fully, though. EDIT: I accidently cross-sent to the dev list. My sincerest apologies :( On 02/24/2012 09:07 PM, Mike Gabriel wrote: >> >> “Loop: >> PANIC!

X2goserver on Ubuntu 10.04.4 server...can't login.
by James Bond 27 Feb '12

27 Feb '12

Hi ! I try x2go on different computer (Ubuntu 11.10 desktop, Debian Squeeze, Debian testing) and all works flawless. But on one server, Ubuntu 10.04.4, I always have this error on the windows client: “The remote proxy closed the connection while negotiating the session. This…” The error in the log: “Loop: PANIC! The remote NX proxy closed the connection. Loop: PANIC! Failure negotiating the session in stage '7'. Loop: PANIC! Wrong version or invalid session authentication cookie.” I try to uninstall and reinstalling several time, but no success. I installed from: deb http://ppa.launchpad.net/x2go/ppa/ubuntu lucid main Thanks for help ! Danny Bélisle

x2gothinclient w/o pxe
by Jonathan Brown 24 Feb '12

24 Feb '12

Hi all, A cursory reading of the online lit I found relating to x2gothinclient seems to require that the stations all pxeboot... I don't want thinclients that pxeboot.. what I need is a minimal OS that is setup to autologin to X and then pyhoca-cli to the x2go-server... can the x2gothinclient packages do this say on a minimal debian install for the thinclient.. ? Since I did not see this capability, I already built from scratch a minimal Debian 6 that does an autologin into X using gdm/matchbox wm, and then created a script that force loops a username/pw graphical dialog using yad (zenity fork)... suffice it to say this works well... but I'm thinking if x2gothinclient already had the capability to do this then I did it all for nought.. except it was definitely a good exercise... The steps and scripts that I did do make this pxe-less x2g0 thin-client/kiosk follow ... I'm sure this can be quite improved... actually the main thing I'd like to improve is to have the matchbox wm/X on the local thin client be aware when there is no activity in the x2go session, and if no activity, then kill or suspend the pyhoca-cli session, thus going back to the yad login prompt, but I haven't found a way to do this (normal logout of the x2go session of course works fine and brings you back to the yad login prompt)... I think the problem is that matchbox wm/X always thinks there is activity when the x2go session is logged in/active, even when there is no activity in the x2go session itself... Any thoughts on any of the above would be appreciated! Steps/scripts etc for x2g0 thin-client/kiosk: OK so I pretty much used the guide from: http://www.alandmoore.com/blog/2011/11/05/creating-a-kiosk-with-linux-and-x… and went from there... After initial Debian squeeze install with only ssh server: Add x2go sources and install pyhoca-cli apt-get install xorg apt-get install gdm --no-install-recommends apt-get install xautolock feh wget http://archive.ualinux.com/ubuntu/main/lucid/yad_0.15.0-1~webupd8~lucid_i38… dpkg -i yad_0.15.0-1~webupd8~lucid_i386.deb (the above is an ubuntu lucid yad deb package but it worked so I didn't ask any further questions :) ... there might be a better yad package for squeeze but I could not find one) adduser kiosk (or whatever) cp -r /home/kiosk /opt/; cd /opt/kiosk/; chmod -R a+r .; touch .xprofile chmod a+x .xprofile my .xprofile: root@lxtrms-thinclient-colodesk:~# cat /home/sagotech/.xprofile xset s off xset -dpms matchbox-window-manager & eval `cat /home/sagotech/.fehbg` & xautolock -secure -time 10 -locker /usr/local/bin/suspend_pyhoca-cli.sh & while true; do rsync -qr --delete --exclude='.Xauthority' /opt/sagotech/ $HOME/ exec /home/sagotech/start_pyhoca.sh done suffice it to say xautolock does not detect non-activity in an x2go session so the suspend_pyhoca-cli.sh never ran: root@lxtrms-thinclient-colodesk:~# cat /usr/local/bin/suspend_pyhoca-cli.sh #!/bin/bash pyhoca-cli -S (for background behind the yad login prompt): root@lxtrms-thinclient-colodesk:~# cat /home/sagotech/.fehbg feh --bg-scale '/usr/share/wallpaper/custom-bk-2.jpg' The script that brings up the yad login prompt loop called from .xprofile follows... so we have this loop inside the loop of the .xprofile script... not sure if this necessary or a good thing etc. root@lxtrms-thinclient-colodesk:~# cat /home/sagotech/start_pyhoca.sh #!/bin/bash while true; do frmdata=$(yad --center --undecorated --image=/usr/share/wallpaper/sago-header-mod.jpg --image-on-top --button="gtk-ok:0" --title "Login to Sago Linux Terminal Server" --form --field="AD username" --field="Password:H") frmusername=$(echo $frmdata | awk 'BEGIN {FS="|" } { print $1 }') frmpassword=$(echo $frmdata | awk 'BEGIN {FS="|" } { print $2 }') pyhoca-cli --server X.X.X.X -u $frmusername --password $frmpassword -c startkde --sound none --kbd-layout us --kbd-type pc105/us -g fullscreen --add-to-known-hosts done The above basically gives you a login prompt and forces you to enter a login AND password and the password is hidden when you type it it puts a nice header image at the top of the prompt.. it only gives an OK button (no cancel)... then passes off the username/pw to pyhoca-cli So yeah I would like to improve this so that inactive x2go sessions get suspended and go back to the yad login prompt... perhaps there is a pyhoca-cli switch that does this that I'm not aware of... But even without that feature this works real nice as a non-pxe x2go thin-client station. Anyway this is all probably very messy and amateurish, but I am not exactly a programmer or very proficient bash scripter so.. :) Also I might be missing a few steps and if any of the above does not make sense please advise and I'll try to see if I missed something in the steps given above... Any thoughts on any of the above would be appreciated! -- *"It is only when each individual has achieved inner peace that we will see lasting outer peace in the world" *

X2Go TCE with new splash
by Mike Gabriel 23 Feb '12

23 Feb '12

Hi all, I have added a much nicer boot splash to the X2Go Thin Client Environment. I also added background support for X2Go Client withint the X2Go TCE. (X2Go Client has had the --background option for a long time already, now it is being used within the TCE by default). You have to build your thinclient chroot from scratch (x2gothinclient_create) and run x2gothinclient_preptftpd again. Backup /srv/tftp and /opt/x2gothinclient before doing this. Happy testing, Mike -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Feature request: Import/export of session profiles
by christoffer krakou 23 Feb '12

23 Feb '12

Hello all I'm employed in a small consultancy company, primarily oriented towards privat schools and their IT needs. When we contact a school, we would like to give them a login to a hosted server via x2go, so they can have a taste of the desktop without a big commitment. Try before you buy, if you will The thing is, Schoolboard members, who decide on this, are somewhat hesitant to read through a guide on how to type in the relevant information themselves. It would be easier for them if they could import a session file that we sent along, using the GUI (i think you can already do this from command line. Not sure though) Also, being able to import and export in general just seems like a nice thing to have. How difficult would it be to implement? I have zero C++ skills myself, so sadly i can only help in the testing of this -- Venlig Hilsen / Best Regards Christoffer Krakou Fleten.net APS
