OK so how do I get a frame buffer driver loaded?

Check if some frame buffer drivers are installed
in your system, so e.g. run

ls /lib/modules/`uname -r`/kernel/drivers/video

to see if there are any frame buffer driver modules
installed.

Then you have to select the suitable driver for your
graphic card and load it by running

modprobe drivername

I don't have any backlisted framebuffer drivers, what is stopping me from
loading a frame buffer driver?

Does anyone know what I have to do?


Usually the driver should be loaded automatically if
it is installed. Maybe some error happened while loading
the driver. Dump the kernel log messages by running dmesg
and check if there was an attempt to load the driver for
your graphic card.

The other case might be a mainsteam GPU (radeon, nouveau, intel) and
KMS support built in (or available as module) but disabled by "nomodeset"
cmdline option that did show up in a previous post.

Just booting with "vga=0x31a" (or another value more appropriate for
attached screen -- see Documentation/fb/vesafb.txt for list) might
provide a basic framebuffer device.

lspci for the affected system will certainly help at least indicating
which driver would be the right one.
