Unable to drop resolutions below 1280x960 on Dell Vostro 1510 with Intel X3100 and WUXGA display
Last modified: 2009-05-08 14:00:15 EDT
Description of problem:
The intel driver is unable to parse the EDID information from the WUXGA display
on a Vostro 1510 with an Intel X3100 video adapter. The result is only
the 1920x1200 resolution is avaialble. I have manually been able to add
resolutions via xorg.conf and xrandr, but there are regressions with regards
to the resolutions that can be displayed. Under Fedora 10, all "normal"/vesa
resolutions were available, due to correct parsing of the EDID data.
Version-Release number of selected component (if applicable):
Always with the Prerelease Fedora 11 (Rawhide)
Steps to Reproduce:
1. Remove xorg.conf from /etc/X11/xorg.conf
2. Start X
3. Go to display settings (Only 1920x1200) available
4. Add modes via xrandr
5. Can only create modes that won't blank display down to 1280x960-60Hz
A. Blank display when manually trying to change resolutions below 1280x960
B. xrandr only shows 1920x1200-60 as a valid resolution
C Starting StarCraft in wine displays the game in the upper left corner of the
screen (at 1920x1200) and runs slow.
From Fedora 10:
A. Change display modes down to 640x480 without blanking display
B. xrandr displays all valid modes between 1920x1200 and 640x400.
C. Running StarCraft under wine should change resolutions and go full screen at
Output from Xorg.0.log will be attached.

No, it's parsing the EDID info correctly, the EDID is just crap and only contains the one mode.
There's a patch for this in CVS but we're not enabling it yet, there's still problems with tiling setup when going in and out of small video modes. Screen full of garbage at the right mode isn't really that useful...
