[X2Go-Dev] Bug#1116: Bug 1116 solved

[star7 at posteo.de]

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

=================================================== My Bug report 
=================================================== Package: x2goserver 
Version: 4.0.5.1 Severity: grave Version client side: x2goclient 4.0.5.1 
on Ubuntu 16 XFCE+ssh server Version server side: x2goversion delivers 
4.0.1.20 on Ubuntu 16 XFCE desktop After a fresh installation of x2go on 
the server and client side without special settings or problems I try to 
just get an xterm. 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 ?? I 
attached the whole log best regards Stefan Auracher $ x2goclient --debug
