Package: xfce4
Version: 4.6.1.1
Severity: important

*** Please type your report below this line ***

I installed xfce4 just to test it.
The installation works, but now i am kicked out of KDE or Gnome sessions
automatically after some time.

I have no idea how this can happen, you can work or not, the session is just 
being
closed and you are back on the login screen.

> So to run Debian with KDE4 you must have a running GLX?

No, KDE4 does not require GLX. However, the KDE window manager checks
if X is capable of doing GLX stuff and in this process it uses some GL
functions.

The problem in your case is that you have installed the nvidia drivers
from the nvidia installer (downloaded from nvidia.com) and you
installed them without knowing that this installer overwrites files
from Xorg/mesa. Then you installed xfce (as stated in bug 534340) and
that probably also caused an upgrade of Xorg/mesa, which overwrote the
files of the nvidia driver again. This makes the nvidia driver to
crash when some application attempts to use GLX stuff. As a result,
you are kicked out of KDE and GNOME sessions because they both have
compositing-aware window managers and try to find and use
compositing/GLX on login if it is available.

> I tried to reinstall the NVIDIA-driver and that was working.

See? ;)  Reinstalling the nvidia drivers overwrites the files again
and it works. So, please switch to using the nvidia-glx package
instead of the nvidia installer or make use of the nvidia installer at
your own risk and taking care to reinstall the driver whenever
something from xorg or mesa is upgraded.

That might be an issue either with NFS or your network connection, but
completely unrelated to the nvidia drivers and/or KDE/GNOME/XFCE.

> I give up now ...

In the future, please refrain from opening bug reports (especially
ones with serious or grave severity) if you don't have enough
knowledge of what is going on. There are user support mailing lists
and forums where you can ask to find a solution to your problem. You
should only file bug reports when you are almost sure that your
problem is a bug in a specific package.

I am closing all three reports that you opened about this "bug":
534672, 534340 and 534421. I hope you didn't file any more bugs about
this in gnome packages... If you did, please close them.

Thanks,
George
