Xorg log file

hi there,
i built xorg from git yesterday using jhbuild. everything seems fine except direct rendering is broken. trying to run glxinfo, for example, yields

[intel_init_bufmgr:593] Error initializing buffer manager.
libGL error: Calling driver entry point failedlibGL error: reverting to software
 direct rendering

this is on a dell latitude d500 running ubuntu 8.10. see the attached logs for more info. (xorg.conf is empty).

looks like the 2d driver is forgetting to allocate the legacy memory space for 3D in the absence of GEM.
Comment 6 Christian Beier 2008-12-14 18:20:14 UTC 
hi,
seems this is fixed in xorg master dating from today, 15. december.
thanks!
