Public bug reported:
I've recently upgraded to karmic.
Unfortunately, KMS does not work with my laptop.
At startup the display is mangled. It seems that only every second line
and column of the display is being used. Thus the display size is
doubled vertically and horizontally. I can only see the upper left
quadrant of the screen.
dmesg shows some errors relating to graphics:
