Control: reassign -= 1 x2goserver 4.0.1.20

First of all, x2goserver 4.0.1.20 actually is the correct stable release. 4.1.0.0 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 version= s is
certainly helpful.

Same issues with bot= h versions.

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.

That is exactly the way =C2=A0I set the locales.

/etc/environment should not contain any locale settings.

/etc/environmnent is empty
=C2=A0

LANGUAGES and especially LC_ALL should normally not be set. LANGUAGES is a<= br> GNU-only list of fallback locales. LANG is the preferred way to set the loc= ale,
since it's being used if all of the LC_* env variables are empty.
"dpkg-reconfigure locales" will do the right thing=E2=84=A2.
<= /blockquote>

I confirm $LANGUAGES and $LC_ALL are not se= t on a local session.

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

I found out it is a reported bug related= to LXDE : cf=C2=A0https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=3D864402

That's certainly possible. The most likely cause, as Uli explain= ed, is that the
command daemonizes itself right after launching it. This leads to the X2Go<= br> 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 anoth= er GTK3
incompatibility.

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
/usr/lib/x86_64-linux-gnu/qt5/examples/widgets/widgets/mousebutto= ns/mousebuttons
which spits out received mouse events.

Can you try that - especially with double clicking - and see what it output= s?
