[Message part 1 (text/plain, inline)]
Package: x2gognomebindings
Severity: important
Version: 2.0.1.6

When a GNOME3 desktop is opened via X2Go in non-fullscreen mode the  
GNOME3 xrandr / monitor settings code does some awful resizing of the  
desktop session window.

Reproduce (GNOME3, also an issue with Unity):

 o you need a client-side display greater than 1024x768
 o set desktop size to 1024x768 in x2goclient session profile settings
 o set desktop session to GNOME on a Debian wheezy server
 o launch session

Compare to KDE4:

 o you need a client-side display greater than 1024x768
 o set desktop size to 1024x768 in x2goclient session profile settings
 o set desktop session to KDE on a Debian wheezy server
 o launch session

What you see:

 o with KDE4 the desktop session window will have the expected size
 o with GNOME3 the window appears in the expected size and then gets resized
   from inside the starting up GNOME3 session
 o in my case: GNOME3 tries to resize to 1920x1200 pixel. The windows gets
   adapted to the greatest size possible on my client display (i.e. the
   window maximizes)
 o However, the desktop shell inside the window does not adapt to the window
   size
 o I can manually resize the window afterwards via the client-side window
   manager (play with your mouse on the window borders...)
 o Still, the desktop shell inside does not adapt its size

This might well be a GNOME3 bug (detection of X server resize events),  
but it normally won't cause problems on physical hardware. So, the  
X2Go team may have to discover a GNOME3 patch for this problem.

Greets,
Mike
