Hmm, the line
(II) [KMS] drm report modesetting isn't supported.
in the X log file indicates that drmCheckModesettingSupported() fails,
i.e. can't find some files in /sys . Alexey, what does
find /sys/bus/pci/devices/*/ -name \*controlD\*
say for you? Note that the asterisk and slash at the end of the second
term are critical, otherwise there will be no results.
You guessed right! It wasn't finding anything until I loaded the radeon
module manually, after which it found
/sys/bus/pci/devices/0000:00:02.0/0000:02:00.0/drm/controlD64
/sys/bus/pci/devices/0000:02:00.0/drm/controlD64
...and KMS in general started working. With KMS enabled, I've got DRI2,
and the original issue of this bug disappeared.
I've added radeon to /etc/modules for now, but I guess I should file a bug
for udev, what do you think?
Now, when I enabled KMS, I got a significant performance degradation
compared to no KMS and no DRI2, but that's a different issue, I'm filing a
new bug about it. Thanks for your help on this one!
