Public bug reported:
Binary package hint: xserver-xorg-video-intel
I have a DELL Latitude D630 notebook with a d/port docking station and a
DELL 2007wfp display which is connected to the docking station with a
DVI plug. The notebook has a resolution of 1440x900. The external
2007wfp Display has a resolution of 1680x1050. When I start the notebook
only the resolution of the notebook panel is detected correctly. But if
the notebook is docked into the docking station GDM and GNOME are
starting with 1152x864 instead of 1440x900 (which is the highest
resolutions both displays support). xrandr -q lists different possible
resolutions in Hardy, Intrepid and Jaunty. Intrepid has the best choice
of possible resolutions even if they are not 100% right.
xrandr -q output of hardy:

I don't know why every ubuntu release lists different possible
resolutions, but it would be nice to have an *easy* possibility to add a
resolution manually.
