Comment 31 for bug 80940

Dell Latitude D600 still shows the bug running karmic beta 1: Displaysize is notauto detected and dpi set to 96 dpi instead of the real 124 dpi. With the size im mm adjusted to the artificial 96dpi. xdpyinfo:

...
screen #0:
  dimensions: 1400x1050 pixels (370x277 millimeters)
  resolution: 96x96 dots per inch
...

Workaround: as karmic does not use xorg.conf in the default setup, I've modified /etc/kde4/kdm/kdmrc to
start the xserver with the options -dpi 124.

Sadly, it looks like radeon driver will never get it right :(
