Start TCE with an empty login field
by Daniel Berteaud 18 Dec '15

18 Dec '15

Hi. When launching x2go client, it always pre-fill the login field with the content of the $USER variable. If this makes sens most of the time, it doesn't when running in TCE: the login field is always x2gothinclient. I tried to change x2gothinclient_start script, by calling x2goclient like: USER="" /usr/bin/x2goclient --no-menu [... etc...] This works, the login field is empty, but this setting also breaks folder sharing (when calling the x2gomountdirs commands, the login arg is empty, so nothing happens) Is there a way to just start x2goclient with an empty login field ?

TCE, no sound
by Daniel Berteaud 16 Dec '15

16 Dec '15

Hi. I'm setting up a X2go TCE env. It's mostly working, but I still have a few issues. One of those issues is that I have no sound on my thinclients. Here's my setup: - PXE server is running Ubuntu 14.04 amd64. Minimal install, only the thinclient management is installed - Thin client chroot has been setup like explained on the wiki (http://wiki.x2go.org/doku.php/wiki:advanced:tce:install) I kept most of the default settings (so the chroot is a debian Wheezy) - X2go server is a CentOS 7 x86_64 box, with the MATE desktop env Thin clients boot fine and can choose between the CentOS/MATE linux desktop or a direct RDP connection (using the xfreerdp client). But, sound isn't working in either case on the client. I've added the module-native-protocol-tcp loading in the chroot (as explained in the FAQ), on the thin client, I can see that pulse is running and accepting connection on port 4713. Where can I start debuging this ? On the x2go server (the CentOS box), I can see the x2go session command: /bin/bash /usr/bin/x2goruncommand 50 30909 fws-50-1450192269_stDMATE_dp24 30004 mate-session nosnd D Is the nosnd param related ? In my session definition, I've added: sound=true soundsystem=pulse startsoundsystem=true soundtunnel=false Did I miss something ? Thanks for your help :-) Cheers, Daniel -- Logo FWS *Daniel Berteaud* FIREWALL-SERVICES SARL.

Compression/graphics
by Dimitri Loizos 04 Dec '15

04 Dec '15

Is there any way to improve the graphics performance of x2go? Either from the server side or from the client side? Even though the general performance of x2go is fast and fluid, when I open specific applications (e.g. LibreOffice Draw or other graphics related applications), the response becomes so slow that it becomes almost unusable. This is not a problem of the host machine: there is plenty of computing power and memory; also, running VNC I do not experience this issue. I was wondering if there were any settings that I could change either on the server side or client side to fix this problem. I'm running x2go server on CentOS (6.7 and 7), and x2go client on Windows 10. The compression that I'm using is 4k-png. Thank you.

x2go and xinerama
by Dimitri Loizos 04 Dec '15

04 Dec '15

Hello, I have been using x2go for a couple of months now and have been very happy with it. My configuration is a server running a virtual machine (CentOS) on it and x2go server running on that virtual machine. I connect to it through the x2go client on Windows 10. One of the features that I love about x2go is its support for multiple displays on the client side through xinerama. I have 2 monitors and x2go treats the session as such. The session will open across both monitors and I can easily maximize windows on each of these monitors. Well, that was until the latest reboot of the server. Now, even though I have the xinerama option on, the x2go client treats my 2 monitors as one: even though the session opens across both monitors, when I maximize a window, it will be maximized across both monitors. I have tried to reset the client, the server, play with different options, but so far to no avail. Any ideas on how I could get the 2 monitor behavior back? Thank you

Kernel panic - not syncing: Attempted to kill init
by Olaf 03 Dec '15

03 Dec '15

Hi! My x2go-TCE actually works. But if I then want to continue to work the next day to the system, the client loads for several minutes until it breaks then with the message ######## ... "Kernel panic - not syncing: Attempted to kill init! ... "Pid: 1, comm: init Not tainted 3.2.0-486 # 1 Debian 3..68-1 + deb" ... "Call Trace" ... "? Panic + 0x4D / 0x139" ... "Do_exit? + 0x75 / 0x598" ... "Do_group_exit? + 0x48 / 0x6B" ... "Sys_exit_group? + 0x11 / 0x11" ... "? Syscall_call + 0x7 / 0x7" ######## A VM that I use as a thin client for testing, writes the same lines, and behind it yet: ######## ... "atkbd serio0: Spurious ACK on isa0060 / serio0 Some Program Might Be Trying access hardware directly." ######## The whole happens if I the next day again test the system, so turn on a client and the system is loaded. The day before, it was always perfect. I've written in the /srv/tftp/x2go-tce.cfg: ######## APPEND .... SELINUX = permissive SELINUXTYPE = permissive ######## After that it was not working for one start, but after that the error comes again. If rebooting the server, the problem is resolved, but the next day it's back. It would be nice if someone would help me. Olaf (PS: Stefan, thank you for your help in the article "Writing through dangling symlink ...", that was the solution. I just do not get how I can respond to the contribution from you on gmane..)

Shared folders and .dot files
by Klaus Fuerstberger 03 Dec '15

03 Dec '15

Hello, I'm sharing a Java application over x2go which is started as single application. Now there is a problem to access the shared folder of the client. x2gomountdirs mounts the folder as a link to /tmp/.x2go-{$USER}/... When the java applications file chooser dialog wants to access /media then the selection jumps to /tmp but cannot find the hidden folder /tmp/.x2go-{$USER} directory, because it is a hidden .dot directory. Is ist possible to change the hardcoded directories to another, not hidden path, eg. /tmp/x2go-{$USER}... and additionally move the temporary files to the users home directory? Thanks! Klaus

Global ssh-agent
by Dmitry Bely 03 Dec '15

03 Dec '15

Hi, I would like to use ssh-agent globally for X session (Debian/MATE if it matters). X session starts it itself and when I login to X locally it works as expected (SSH_AGENT_PID and SSH_AUTH_SOCK environment variables are set correctly). But if I connect to the host via x2go, strange things happen: in any terminal session SSH_AUTH_SOCK points to non-existing path and SSH_AGENT_PID is not set at all. I tried to work around this adding to ~/.bashrc: if [ ! -S ~/.ssh/ssh_auth_sock ]; then eval `ssh-agent -s` ln -sf "$SSH_AUTH_SOCK" ~/.ssh/ssh_auth_sock fi export SSH_AUTH_SOCK=~/.ssh/ssh_auth_sock This way SSH_AUTH_SOCK is correct but SSH_AGENT_PID is surprisingly unset somethere. Any idea how to fix that? - Dmitry Bely

cp: not writing through dangling symlink /opt/x2gothinclient/chroot/etc/x2go/x2gothinclient_init
by Olaf 02 Dec '15

Hi Stefan! The adding extra spaces before and after "/" are from google translator. I have not seen that after copying / before paste the text, sorry. Thank you for "TC_X2GO_DEBURL = deb http://packages.x2go.org/debian wheezy main" It works now. Bye, Olaf (PS: I am not sure if this posting will be there at the correct place, in the thread. I did not receive any mail after the Authorization-Mail, and I do not see any "reply"-Button on this gmane-page.)

Re: [X2Go-User] Debian Jessie + Openbox / Not working keyboard shortcuts
by Lmhelp1 01 Dec '15

Hi René, Thank you for your answer. > does ctrl+alt+tab work for you to switch windows? Unfortunately not. [X2Go client is installed on a Windows OS.] [X2Go server is installed on a Debian Jessie OS.] [The session is an OpenBox session.] ctrl+alt+tab allows me to switch from one Windows OS window to another... Thanks for helping.
