[Bug 573312] [NEW] Wrong resolution in GDM when using external monitor connected to laptop - Intel chipset

 

Public bug reported:

I have an HP laptop, with an external monitor connected to RGB. The
graphics is Intel mobile. I will post some relevant files after this.

When I boot, xsplash treats the external monitor correctly, and the boot
screen is quite beautiful at 1650x1080 resolution.

But right before gdm starts, the same boot screen suddenly turns to I
think 1280x800 on the external monitor, after which gdm is displayed the
same way.

As a side note, I used to have this problem also in Kubuntu i686, before
installing Ubuntu. However, the problem was not there a while ago, when
using Karmic. I don't remember exactly if it started happening once I
started using Lucid.
