[Bug 286001] Re: [g45] Incorrect resolution when docked on Dell Latitude E6400

[Kai Jauch]

Sorry that it took so long for me to respond.
I tested it with xserver-xorg-video-intel 2:2.8.0-0ubuntu1 and linux-image-2.6.31-4-generic 2.6.31-4.23 and observed the following behaviour:

Booting docked with DVI1 attached, lid closed/open (doesn't make a difference):
- If lid is closed, only DVI1 is enabled by BIOS, LVDS1 disabled
- KMS enables both outputs, DVI1 at 1600x1200, LVDS1 at 1440x900 (both are the native resolutions for the respective displays). Usplash centered on LVDS1, top left corner on DVI1 (that's fine)
- GDM starts, LVDS1 and DVI1 are set to 1152x864

Booting undocked with nothing attached:
- KMS sets LVDS1 to 1440x900
- GDM uses the resolution set via KMS


To summarize:
The resolutions set by KMS are right in all cases, GDM sets a common resolution for all connected displays (1152x864).
