Xorg.0.log without KMS
The difference in the possible configuration available is quite clear with the xrandr command output. Without KMS: Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 2560 x 1200 VGA-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 355mm x 265mm 1600x1200 85.0 75.0 1280x1024 85.0* 75.0 60.0 1152x864 75.0 1024x768 85.0 75.0 70.1 60.0 43.5 832x624 74.6 800x600 85.1 72.2 75.0 60.3 640x480 85.0 75.0 72.8 66.7 59.9 720x400 87.8 70.1 DVI-0 disconnected (normal left inverted right x axis y axis) S-video disconnected (normal left inverted right x axis y axis) With KMS: Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 4096 x 4096 VGA-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 355mm x 265mm 1600x1200 85.0* 1280x1024 75.0 1152x864 75.0 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 640x480 72.8 75.0 66.7 60.0 720x400 87.8 70.1 0x0 0.0 DVI-0 disconnected (normal left inverted right x axis y axis) Still applies in 2.6.31-0.125.4.2.rc5.git2.fc12.i686 Works much better now in the Radeon Test Day ISO image (09/09/09). Now KMS detects even more resolutions than the old method. [liveuser@localhost ~]$ uname -a Linux localhost.localdomain 2.6.31-0.219.rc9.git2.fc12.i686 #1 SMP Wed Sep 9 06:12:03 EDT 2009 i686 athlon i386 GNU/Linux [liveuser@localhost ~]$ xrandr Screen 0: minimum 320 x 200, current 1920 x 1440, maximum 4096 x 4096 VGA-0 connected 1920x1440+0+0 (normal left inverted right x axis y axis) 355mm x 265mm 1920x1440 60.0* 1792x1344 60.0 1600x1200 85.0 75.0 1280x1024 85.0 75.0 60.0 1152x864 75.0 1024x768 85.0 75.1 70.1 60.0 832x624 74.6 800x600 85.1 72.2 75.0 60.3 640x480 85.0 72.8 75.0 66.7 60.0 720x400 87.8 70.1 DVI-0 disconnected (normal left inverted right x axis y axis) S-video disconnected (normal left inverted right x axis y axis) So this is fixed in rawhide. I'll let you know if I detect progresses in F11 too. Created attachment 360456 [details]
dmesg with KMS now working properly.
Kernel 2.6.31-0.219.rc9.git2.fc12.i686 fixes the problem.
