Num Lock key in windows agent
by Olivier BILHAUT 24 Nov '16

24 Nov '16

Hi all. First of all, I'd like to congratulate all the contributors for this great work. X2go is a professional class tool for remote desktop. However... I ran into a really special thing using the windows agent in its last version (4.0.5). Sometimes, when you open the session, the "Num Lock" is usable, sometimes not. I mean, sometimes you may push the caps lock button and switch from arrows to Numeric keys, and sometimes the Key Pad is fully unusable. It happens only on windows agent as far as I know. All that I tried did not solve the issue. Did you already encounter that? Thanks. -- OB SySAdmin Fondation Hospitalière de la Miséricorde

x2goclient session icons not working
by Will Wagner 23 Nov '16

23 Nov '16

Hello, I have upgraded to 4.0.4.0 on win32. It's a minor thing but if I now set a session icon for a connection it is not displayed and I get blank instead. Is there something I need to do to get this to work? Thanks Will

Scientific Linux 6 XFCE issue
by James M. Pulver 28 Jan '16

28 Jan '16

It seems that when we run XFCE or custom desktop xfce4-session, we get the same result over X2Go for XFCE - one panel, that is empty. This is not what we get logging into XFCE on the local console of the computer. Google shows this is often an issue on Ubuntu derivatives, or was several years ago. Has anyone else had this issue on RHEL derivatives? Any idea why it doesn't seem to get the expected panel settings? -- James Pulver CLASSE Computer Group Cornell University

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

Debian Jessie + Openbox / Not working keyboard shortcuts
by Lmhelp1 30 Nov '15

30 Nov '15

Hello, I am using Debian Jessie + Openbox. When logged into the machine itself (not via X2Go), I usually hit the keyboard keys Meta + t to start a new XTerm. To be able to do this, I added the following keybind into the OpenBox configuration file "/etc/xdg/openbox/rc.xml": ======================================== <keybind key="W-t"> <action name="Execute"> <command>xterm -fn 10x20</command> </action> </keybind> ======================================== Hitting Meta + t, successufully starts a X terminal. Also, I can hit: Ctrl + Alt + F1 to F6: to switch to the first to the sixth console. Ctrl + Alt + F7 : to switch to desktop mode. These keyboard shortcuts do not work when I am logged into the machine via a X2Go client. Is there something I can do to make these shortcuts work? Thank you and best regards. -- Léa Massiot

sshfs issue
by Robert Fantini 30 Nov '15

30 Nov '15

Hello I've not been able to get remote print working. The issue seems to be with this: # ls -l /tmp/.x2go-rob/spool ls: cannot access /tmp/.x2go-rob/spool/C-rob-63-1448653826_stDLXDE_dp24: Permission denied total 0 d????????? ? ? ? ? ? C-rob-63-1448653826_stDLXDE_dp24 mount shows: rob@127.0.0.1:/home/rob/.x2go/S-rob-63-1448653826_stDLXDE_dp24/spool on /tmp/.x2go-rob/spool/C-rob-63-1448653826_stDLXDE_dp24 type fuse.sshfs (rw,nosuid,nodev,relatime,user_id=1700,group_id=1001,default_permissions) I tried installing latest x2go on a Jessie and Mint system with the same result. Any clues on how to solve this? best regards Rob Fantini

x2go compatable distro / release
by Robert Fantini 30 Nov '15

30 Nov '15

Hello I've been using Jessie and Mint on virtual machines and on hardware, but can not seem to get remote print working - due to an sshfs issue. I posted in an earlier email a few days ago. If you have remote print working, could anyone please report back which distro / release works? best regards, Rob Fantini
