Hi, Since r296548 using graphics mode 2560x1440 no longer works. The screen flicks rapidly through many colours if I choose this mode. The DRM attach produces the following output: info: [drm] Initialized drm 1.1.0 20060810 drmn0: <Intel IvyBridge (M)> on vgapci0 info: [drm] Memory usable by graphics device = 2048M info: [drm] MTRR allocation failed.
