https://bugs.freedesktop.org/show_bug.cgi?id=39202 --- Comment #34 from Siganderson <dj_def@xxxxxxxxxx> 2011-08-18 09:52:25 PDT --- (In reply to comment #33) I booted into kde 4.7.0 with a 3.1.0-rc2 kernel and then I did: echo 7 > /sys/module/drm/parameters/debug and then I launched glxgears (and didn't close it). Then I did: dmesg | grep waiting [ 329.830313] [drm:drm_wait_vblank], waiting on vblank count 19676, crtc 0 [ 329.834052] [drm:drm_wait_vblank], waiting on vblank count 19677, crtc 0 [ 329.834068]
