https://bugs.freedesktop.org/show_bug.cgi?id=39202 --- Comment #27 from Michel Dänzer <michel@xxxxxxxxxxx> 2011-08-18 03:00:16 PDT --- (In reply to comment #25) > There is a sequence of commits in drm, some of them related to radeon > and vblank. I guess it's most likely commit 19b01b5fbf0b78930b3b06ee6080539c17b5d1fd ('drm/kernel: vblank wait on crtc > 1') that makes the difference. Without that commit, the X driver completely disables vsync functionality with your card, as it can't work on some of the CRTCs. What I don't understand is why the suggested workarounds don't restore the previous behaviour... did you leave all of them (disabling page flipping and SwapBuffersWait — verify in Xorg.0.log that they're really disabled — and vblank_mode=0) enabled at the same time? Missing any one of them could result in vsync being effectively enabled. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
