Description christian_obst 2006-07-21 15:47:50 UTC
Although glxinfo reports that Direct Rendering is enabled, several 3D apps do
not work, because they complain about DRI _not_ being enabled/software mesa
being enabled (tremulous), or simply crash and freeze the system (xscreensaver,
amoeba). However, glxgear works accelerated. I also tried the mesademos. I
attach the results along with the output of lspci -v, my /var/log/Xorg.o.log,
and the output of glxinfo. I am using the latest Openchrome driver (trunk 194)
on Debian testing. My kernel is

Do the failing programs work correctly if LD_PRELOAD is used to force the
correct loading of libGL?
Comment 6 christian_obst 2006-07-21 16:47:06 UTC
Actually, yes. tremulous (its an opensource 3D game) now starts up nicely and
does not complain about software mesa anymore. However, after a few minutes of
playing, it freezes. Sometimes I can switch to a console and kill it, but
sometimes I can't, and even if I can, the system stays unusable (X screen has
artefacts, system very slow, eventually freezes completely).
As for the mesademos, LD_PRELOAD does not help. But I don't think you meant
them, anyway.
