Package: x2goserver Version: 4.0.5.1 Severity: grave
The problem was similar to bug 1091 I solved it by removing the command setxkbmap from my .profile The error handling should be improved. The error message "Unable to open display" is here confusing. Better would be something like "got output on stderr during login therefor exit"
Thanks a lot: I installed x2go now the first time and it is running on Ubuntu 16 server + client; both with xfce
I still have problems with sound forwarding

I have the following severe problem: Running x2goclient with --debug shows sucesfull SSH connection established. But after this the exec channel closes with "Have stderr only, something must be wrong." In the GUI a message "Cannot open display "default display"" shows up The message SSH finished: raw output (stdout): "setxkbmap -option ctrl:nocaps" could be a hint that some error processing during login does not work ?? Any idea how to debug ??

Note that you don't have to remove it completely; wrapping it in a check like
if test -t 0; then your-command-here fi
should do. This test will only return true if you're runniny a TTY session, which X2Go does not.

May I suggest you subscribe to x2go-user as well, ask your questions there, and open a new bug if it turns out to be an actual bug and not user error?

For commands expecting a TTY (e.g. "mesg"), yes. setxkbmap should not be wrapped into this, but rather $DISPLAY checked for existence *and* its stderr messages redirected either to a file or to /dev/null. In reality, this call doesn't belong in ~/.profile at all, but I'll leave that to the user to sort it out...
Closing up.
