Intel Framebuffer doesn't work on a notebook
I have a Notebook with an Intel VGA-Controller and the
framebuffer will not work. Any idea what could be wrong?
What does the line mean 'Video mode must be programmed at boot time'?
How can I do this? There is no parameter, which I can give in the
'make menuconfig' process.
The controller is ('lspci | grep VGA'):
00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)
The command line (in grub) is:
root=/dev/hda3 ro video=intelfb:mode=1024x768-32@60 resume=/dev/hda6
And the relevant part of dmesg:
intelfb: options: mode=1024x768-32@60
