Hi,

currently only a part of this bug is reproducible. The error message
does not appear anymore, but changing resolutions, enabling/disabling
monitors etc. does not work. Whatever I do in this dialogue, absolutely
nothing happens when I click "apply".

Changing resolutions etc. on the command line works well.

My monitor setup is as follows:

Screen 0: minimum 320 x 200, current 3200 x 1200, maximum 8192 x 8192
DVI-0 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 546mm x 352mm
   1920x1200      60.0*+
   1600x1200      60.0  
   1680x1050      60.0  
   1600x1000      60.0  
   1280x1024      75.0  
   1280x960       60.0  
   1152x864       75.0  
   1024x768       75.1     60.0

   720x400        70.1  
DIN disconnected (normal left inverted right x axis y axis)
DVI-1 connected 1280x1024+1920+0 (normal left inverted right x axis y axis) 376mm x 301mm

   1152x864       75.0

   720x400        70.1  


I tried to produce the gsd-debug-randr.log, but didn't succeed (although I did a logout/login):

philipp@pc-philipp:~$ ls -l gsd*

Title:
  Setting screen resolution fails with error message "null"

Status in “gnome-control-center” package in Ubuntu:
  Incomplete

Bug description:
  After upgrading from Natty to Oneiric, my second monitor was disabled
  on first login. I opened the resolution dialogue via the system menu
  and enabled it (both monitors and their resolutions were correctly
  shown in this dialogue). After clicking "apply", nothing changed but a
  popup box appeared saying "The chosen screen configuration could not
  be applied (null)".

  Obviously, changing the resolution should work (it did in Natty), and
  if it fails, the message should be more helpful than "null".

  I have a Radeon HD 4870 and use the usual radeon driver.

  Manually enabling the second monitor with xrandr led to a Compiz
  crash, but I'll file a separate bug about that if I can reproduce it.
