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.
