Title:
  Resolution switches to 1280*720 after locking screen (if it goes
  blank)

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  After turning off screen (by locking it and waiting till it goes
  blank) Ubuntu switches resolution to 1280*720 and does not allow me to
  go back to 2560*1440 (my monitor's native resolution). There is only
  1280*720 and 800*600 option available in both amd panel and ubuntu
  display settings.

  My setup is:

  Sapphire Radeon 6950 2GB connected through mini-dp to an iMac 27
  (acting as monitor).

  It used to work fine since 12.10.
