A login manager such as gdm or kdm, or a user session?

As a quick'n'dirty test, you could try compiling the 2.6.35 radeon driver with KMS_DRIVER_MINOR modified to 3 in drivers/gpu/drm/radeon/radeon_drv.c . If that works around the problem, it's probably indeed related to the GLX sync extensions, and there's probably no point in bisecting the kernel. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org http://lists.x.org/mailman/listinfo/xorg-driver-ati
