xorg.conf

The radeon driver does not correctly set the resolution in 6.12.2 or git as of 05-24-09. The native resolution for my monitor is 1280x1024@60 but radeon sets it to 1024x1024. I can use cvt and xrandr and a Virtual line to set the correct resolution, but since radeonhd correctly sets the resolution, I believe this is a bug in radeon. Using xrandr to fix the resolution also causes many of the fonts on the windows to be much smaller than normal, but I'm not sure if this is related.

I have the following options set for radeon driver in xorg.conf :
 Option DDCMode "On"
 Option EnablePageFlip true
 Option AccelMethod EXA
 Option DRI on

I have had to add the following line in the Display subsection :
 Virtual 2048 2048

I am running slackware 12.2, but it's version of xorg isn't based on a specific release, so I don't know what version to call it. I've upgraded mesa, libdrm, and the kernel to versions 7.4.2, 2.4.11, and 2.6.29.3 respectively myself. If additional version info is needed, please request it. I can also attach screenshots of my desktop from radeonhd and radeon if desired.

Bugs 11902 and 11897 may be related.

The modes are being limited by the sync ranges specified in your xorg.conf:

    HorizSync   31.5 - 50.0
    VertRefresh 40-90

(II) RADEON(0): EDID vendor "VSC", prod id 44316
(II) RADEON(0): Using hsync ranges from config file
(II) RADEON(0): Using vrefresh ranges from config file

Remove those lines from your monitor section and it should work fine.
