You ought to be able to get at least VESA stuff.
In xorg.conf, if I replace vga by vesa for driver, and if I try to startx, it failed and I get the following (incomplette) message:
(EE) VESA(0): No matching modes (EE) Screen(s) found, but none have a usable configuration.
As my default xorg.conf was created with pyxf86config, there is no mode neither modelines defined.
As root, from a console in run level 3 (telinit 3), try
I'm in this run level since installation.
system-config-displayI tried this, but as it is running in a 320x200 vga mode, I can't see a lot of things. I think I see less than a quarter of the dialog window.
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.
IIRC, vga=ask will do it, otherwise pick one like vga=0x317, and it will prompt if invalid. http://en.wikipedia.org/wiki/VESA_BIOS_Extensions
