This is a bug report from a Ubuntu reporter: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/190506 "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 1280x1024 instead of 1680x1050. I can change the resolution manually but after the next boot the resolution is 1280x1024 again. (The behaviour of Gutsy is completely different but not really better ;-) Ubuntu Hardy Alpha4 64bit xrandr -q Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 1920 x 1200 VGA disconnected (normal left inverted right x axis y axis) LVDS connected (normal left inverted right x axis y axis) 1440x900 60.0 + 50.0 1280x800 60.0 1280x768 60.0 1024x768 60.0 800x600 60.3 640x480 59.9 TMDS-1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 434mm x 270mm 1680x1050 59.9*+ 1280x1024 75.0 59.9 1152x864 74.8 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 TV disconnected (normal left inverted right x axis y axis)" We had him attempt hardcoding the config, and specifying the preferred mode, but this didn't change the behavior.

The xrandr output in Intrepid is different than in Hardy. Now there are more/other supported modes. Now I have a resolution of 1440x900 on both displays when GDM appears which is much nicer. xrandr -q Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 1680 x 1950 VGA disconnected (normal left inverted right x axis y axis) LVDS connected (normal left inverted right x axis y axis) 1440x900 60.0 + 50.0 1360x768 59.8 1152x864 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 TMDS-1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 434mm x 270mm 1680x1050 59.9*+ 1600x1024 60.2 1400x1050 60.0 1280x1024 75.0 60.0 60.0 1440x900 59.9 1280x960 60.0 1360x768 59.8 1152x864 75.0 75.0 75.0 70.0 60.0 1024x768 75.1 75.0 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 75.0 72.8 75.0 60.0 59.9 720x400 70.1 TV disconnected (normal left inverted right x axis y axis)
Sounds like it works then.
