Hi,
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'?
It means that you need to set video mode at boot time
The command line (in grub) is:
root=/dev/hda3 ro video=intelfb:mode=1024x768-32@60 resume=/dev/hda6
In that line, I think, you need to add extra parameter "vga=". I'm using
"vga=791", which means 1024x768, 16bit. Set it in /boot/grub/menu.lst. My
looks like this:
kernel /boot/vmlinuz-2.6.18-4-686 root=/dev/hda6 ro vga=791
Here is a tables, which shows available frame buffer vga modes
Color depth | 640x480 800x600 1024x768 1280x1024
-----------------+-------------------------------------
256 (8bit)| 769 771 773 775
