It may work for reconnects or new sessions for some time. Currently I have machine that is in the state of 'no terminal opening'. I opened a new session to it. The session does not show up in the list produced by 'sudo x2golistsessions_root' on the machine. Therefore I have no way to terminate the session. I can find the session-ID string in the X2Go client window. If I connect to the server via ssh, and use 'sudo x2goterminate-session ' , nothing happens. The session is still running. > 2. does it make a difference if you reconnect from a Linux client?

When I use the clients 'Sitzung beenden' button, there is a confirmation dialog popping up.

Re: [X2Go-User] No terminal windows, no logout.
Another observation: If I have a remote desktop open, and open a separate ssh-connection to the server, then export DISPLAY=: xterm & opens a terminal window on the remote machine and displays it in the x2go window.

Re: [X2Go-User] No terminal windows, no logout.
Hi Ulli, I tried to move .bashrc out of the way, this did not solve the problem. Also moving .bashrc and .profile out of the way did not help. I am not sure if stale mounts can cause this problem, because I am still able to open a remote shell via ssh.

[X2Go-User] No terminal windows, no logout.
Hi, we use x2go for multiple users to connect to workstations running Ubuntu 16.04.6 LTS. Clients run on MacOSX or Windows machines. After using the setup for some days with multiple reconnects, for unknown reasons we can no longer open terminal applications via these remote-desktops. This applies to all terminal applications like UXTerm, Xfce Terminal, XTerm, etc. We can still perfectly open a file manager, or e.g. Matlab and work with those. We can also no longer close the session because the confirmation dialog to confirm user logout does not appear. It seems like there is a terminal process started every time we start a terminal via the desktop GUI. But the window does not show up. After rebooting the workstation, everything works fine again, terminals can be opened, logout confirmation dialog pops up. Currently we use XFCE desktop.

Re: [X2Go-User] Problems with X2go keyboard layout - solved
Problem is solved: On the client, in the XQuartz settings, I activated the option 'Tastaturbelegung des Systems verwenden' On the server, inside the remote desktop I changed the keyboard settings to 'Layout: use system defaults'. I will not further investigate which of the options did it.

Re: [X2Go-User] SSH-Daemon could not be started on MAC OSX 10.11.6
I did not change the port, so it should be listening on the default port 22. The client setting for the local SSH-port for file sharing is 22. We need file sharing and printer support, therefore it is not an option to suppress the warning message by disabling these functions.

[X2Go-User] x2go overwrites LD_LIBRARY_PATH
Hi, I am using x2go to connect to machines running Ubuntu 14.04.3 LTS. I had trouble running commands that rely on finding libraries via the environment variable LD_LIBRARY_PATH. LD_LIBRARY_PATH is set in a script in /etc/profile.d because this is a system wide configuration and it needs to be performed once per login. Using ssh to remote login, LD_LIBRARY_PATH is correct: echo $LD_LIBRARY_PATH /usr/lib/fsl/5.0 When I login using x2go, LD_LIBRARY_PATH seems to be reset and contains only the entries regarding x2go: echo $LD_LIBRARY_PATH /usr/lib/nx/X11/Xinerama:/usr/lib/nx/X11 My guess is that there is probably an error in /usr/bin/x2goruncommand, along these lines: test -n "$LD_LIBRARY_PATH" && \ LD_LIBRARY_PATH="$NX_XINERAMA_LIBS:$NX_LIBS:$LD_LIBRARY_PATH" || \ LD_LIBRARY_PATH="$NX_XINERAMA_LIBS:$NX_LIBS" "$X2GO_LIB_PATH/x2gosyslog" "$0" "debug" "exporting LD_LIBRARY_PATH=$LD_LIBRARY_PATH" export LD_LIBRARY_PATH But I can not see why it is that my path only contains $NX_XINERAMA_LIBS:$NX_LIBS, and not $NX_XINERAMA_LIBS:$NX_LIBS:$LD_LIBRARY_PATH.
