Xorg.log without configuration file
Without xorg.conf or with a pixel depth of 24 bits, any application linked to
libGL will fails to load the "r300" driver and after it the "swarst" driver
with the following message:
libGL error: failed to load driver: r300
libGL error: Try again with LIBGL_DEBUG=verbose for more details.
libGL error: failed to load driver: swrast
libGL error: Try again with LIBGL_DEBUG=verbose for more details.
This problem is present in all the Mesa 9.x release up to 9.2.3. But it is not
in the 8 (which segfault at some point), 7.11 was working without config file.
After a bit of investigation, I found that driConvertConfigs() returns NULL in
dri2CreateScreen() when trying to find matching visuals
(src/glx/dri_glx.c:450). However if I specify a depth of 16 bits in my
xorg.conf I cannot reproduce this problem.
This problem is present on OpenBSD -current (future 5.5) which has the drm
drivers synced with Ubuntu's linux 3.8 kernel.
