I rebooted the machine clean to the command line prompt and then typed |
| 29 |
|
| 30 |
modprobe i915 modeset=0 |
| 31 |
|
| 32 |
and except for the first 3 lines everything below was created in |
| 33 |
dmesg. At this point the screen s black and the light on the front is |
| 34 |
blinking like it does when the computer is turned off. |
| 35 |
|
| 36 |
I haven't been able to solve the MTRR thing yet. I've tried a bunch of |
| 37 |
different settings but it doesn't change those results. |
| 38 |
|
| 39 |
Is it typical to call the device a 'fb0: inteldrmfb frame buffer |
| 40 |
device'? I assume that's not the i915 but rather the drm? |
