Time for extreme measures. At boot prompt, add to the end of the kernel
line, via the grub edit facility "vga=ask", IIRC.

I can't find the kernel parameters docs on my system ATM, so this is a
guess from memory. Maybe I need kernel development to get those notes?

Anyway, that should give you a list of pre-defined modes, numeric.
Google before you do this and get a list of possible ones. I would pick
the 1024x768 as a first try. IIRC another is 800x640. There's a
1240x1076(?) I think too.
