[X2Go-Dev] Bug#1200: Environment variables not set

Control: reassign -1 x2goserver 22.214.171.124
First of all, x2goserver 126.96.36.199 actually is the correct stable release.
188.8.131.52 are the current nightly releases.
I personally don't care much about what version is tested, but knowing whether
there's a difference in behavior between the stable and nightly versions is

How exactly did you set the locale?
The "Debian way" would be to run dpkg-reconfigure locales as root and select the
desired locale(s) to generate and then select the default one.
/etc/environment should not contain any locale settings.
LANGUAGES and especially LC_ALL should normally not be set. LANGUAGES is a
GNU-only list of fallback locales. LANG is the preferred way to set the locale,
since it's being used if all of the LC_* env variables are empty.
"dpkg-reconfigure locales" will do the right thing™.

What session are you starting exactly? I cannot find the string "No session for
pid" in x2goserver's source code. Not sure what to do with this.

That's certainly possible. The most likely cause, as Uli explained, is that the
command daemonizes itself right after launching it. This leads to the X2Go
scripts assuming that the program exited and subsequently also terminating the
session. We've seen such behavior every now and then and worked around it.
However, it looks like x2goagent is crashing when you start libreoffice in your
case. That shouldn't happen. My gut feeling is that this might be another GTK3
I could try to reproduce this in a clean stretch VM.

That sounds like Gambas is doing something funny, though. As far as I was able
to gather, Gambas seems to be using Qt5 as its drawing toolkit.
The package qtbase5-examples should contain a binary at
which spits out received mouse events.
Can you try that - especially with double clicking - and see what it outputs?
