Created attachment 29409 [details] output of "avivotools regs" with kms enabled When booting the system with KMS enabled, the screen is stuck in 1280x1024@60, even though dmesg (and xrandr in X) say that the active mode is 1920x1200. The area available in X is indeed 1920x1200 (programs occupy the usual space) but it is scaled (and stretched) to fit into 1280x1024. Changing the resolution via xrandr influences the space available to programs while the resolution remains the same. gpu: 2x hd4850 screen: 1x samsung syncmaster 2493HM kernel: drm-next 2.6.31-rc9-27054-g6cf8a3f driver, mesa, libdrm: git master (Fri Sep 11, 9h GMT+1)
