Sounds like you fell for the drm_vblank_on/off propaganda. :( This was working fine with drm_vblank_pre/post_modeset, that it broke is simply a regression. I'm not against switching to drm_vblank_on/off for 4.6, but it's not a solution for older kernels. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer
