  Using xrandr with dual monitor causes garbled image

Status in “linux” package in Ubuntu:

Bug description:
  Binary package hint: xorg

  Almost every time I use xrandr to setup my monitors I get garbled,
  unusable desktop. The system remains perfectly working (no lockups,
  mouse pointer visible and working, desktop responsive to inputs: I
  could continue use it blindly). With some more details:

  - If I change the configuration of a monitor, I get the garbled
  desktop. Reverting to previous configuration does not work (still
  garbled). Sometimes I got an usable desktop (blindly) configuring
  monitors with very low resolutions (800x600 or 640x480).

  - The issue often occurs even doing a simple xrandr query (with CLI or
  opening the GUI).

  - If I start my laptop with the external monitor plugged, gdm starts
  fine (with low resolution on both monitors, though), gnome starts fine
  with both monitors well working at right resolution (1280x800+0+224,
  1280x1024+1280+0). Changing the configuration of a monitor triggers
  the issue.

  As a side node, things work perfectly with Fedora 13 Beta live DVD
  (apart from xorg crash when rotating a monitor at maximum resolution).
  So the issue maybe related to xorg 1.7.6 and solved in xorg 1.8.
