Comment 11 for bug 197680

Hi,

I've been running
$ xrandr --output DVI-0 --rotate left --verbose
  crtc 0: disable
  screen 0: 768x1024 202x270 mm 96.09dpi
  crtc 0: 1024x768 75.1 +0+0 "DVI-0"

or
$ xrandr -r 1

which renders my screen almost unusable (mouse cursor looks weird, border of the screen or switching apps preview looks weird -a lot of different, senseless colors).

I'm using ubuntu hardy on x86 with ati radeon driver installed
