Bug Description

Binary package hint: xorg

2.6.30 KMS correctly uses the 1920x1200 resolution of my LCD. 2.6.31 does not (it chooses 1024x768).

Hrm, I attempted to do bug data collection in the failed state, but it did not do the right thing. :( The attached reports are all from the working 2.6.30. I will try again...

The broken log (in the "saved report" attachment) lacks the 1920x1200 line in the "probed modes" section:

(II) intel(0): Printing probed modes for output DVI1
(II) intel(0): Modeline "1920x1200"x60.0 154.00 1920 1968 2000 2080 1200 1203 1209 1235 +hsync -vsync (74.0 kHz)

<bryce> jbarnes, so like, if xrandr is unable to show/set non-vesa
resolutions when booted in KMS?
<jbarnes> no that's a separate bug, also fixed in git
<jbarnes> that was due to our kernel code not populating a full mode
list for panels like the 2d driver did

As per jesse, there's a kernel fix in git for this, so refiling to the kernel.

HI Kees and Bryce,

Sorry for the delay was away on holiday. I'll get this on the kernel team's radar. Thanks.
