Priority: medium Bug ID: 71789 Assignee: dri-devel@lists.freedesktop.org Summary: [r300g] Visuals not found in (default) depth = 24 Severity: normal Classification: Unclassified OS: OpenBSD Reporter: mpi@openbsd.org Hardware: PowerPC Status: NEW Version: 9.2 Component: Drivers/Gallium/r300 Product: Mesa
Created attachment 89467 --> https://bugs.freedesktop.org/attachment.cgi?id=89467&action=edit 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.
