Hi Daniel,

Just as a counter feedback. I have tested nxcomp 3.5.0-2 on several systems (Debian squeeze, Ubuntu lucid) and the problem does not occur here.
However, I have observed such failures before. Does the problem persist after server reboot (that is after restart of dbus & co)?
Yep, I've tried "everything". I can start a Gnome or Xfce session locally (on the console), but x2go desktop sessions just don't work.
Tried starting Xfce session in x2go, I can just see the desktop coming before the window disappears, this is in auth.log

No dbus errors.
Starting a single application works, tried gedit and gnome-terminal. Nothing in auth.log from dbus or policykit.
Please switch to loglevel=debug in /etc/x2go/x2goserver.conf and see
what syslog brings then.
If you have not updated x2goserver.conf yet then place this stanza
into the file
[log] # possible levels are: emerg, alert, crit, err, warning, notice, info, debug loglevel=debug
Thanks, mike

Thanks for the tip, unfortunately /var/log/debug didn't give me any additional clues to what the problem was.
After several hours of troubleshooting I finally gave up, removed and reinstalled Gnome. So far it's looking good, I can start sessions and reconnect to them. I'm using nightly builds, i e the new libxcomp3, and it works. I guess the problem was in Gnome/dbus alone or some combination of them and x2go.
Cheers, Daniel
Still having problems, I can log in but sessions die on me several times a day.

The session is completely gone from the server, as if I'd logged out.
I have the latest nightly packages installed (ie x2goagent 3.5.0.5) on both client and server.

we ourselves are neither really happy about the changes in nxagent and
we will have to take a closer look still. Note, the nightly builds are
the developers' testing packages.
Currently, x2goagent from nightly builds is not at all recommended.
Greets, Mike
