Disable KMS in the i915 driver: > =C2=A0 . When built as a module, use the "modeset=3D0" parameter I rebooted the machine clean to the command line prompt and then typed modprobe i915 modeset=3D0 and except for the first 3 lines everything below was created in dmesg. At this point the screen s black and the light on the front is blinking like it does when the computer is turned off. I haven't been able to solve the MTRR thing yet. I've tried a bunch of different settings but it doesn't change those results. Is it typical to call the device a 'fb0: inteldrmfb frame buffer device'? I assume that's not the i915 but rather the drm? - Mark e100: eth0 NIC Link is Up 10 Mbps Half Duplex NET: Registered protocol family 10 eth0: no IPv6 routers present [drm] Initialized drm 1.1.0 20060810 i915 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 i915 0000:00:02.0: setting latency timer to 64 mtrr: type mismatch for c0000000,10000000 old: write-back new: write-combin= ing [drm] MTRR allocation failed.
