OS: Ubuntu 12.04.

Driver: radeondrmfb.

Driver source: Ubuntu distribution.

Hw: ATI HD 3000 series.

Hi. Please, help me change frame buffer screen resolution. I try following kernel command line parameters:

video=radeon:800x600-32@60

video=radeonfb:800x600-32@60

video=radeondrmfb:800x600-32@60

gfxpayload=800x600

video=800x600

All it's don't work. Every reboot I have maximum screen resolution.

I try `fbset`, but it only change virtual screen resolution.

Also i can't find `man {radeon,radeonfb,radeondrmfb}`

There are way for change screnen resolution via kernel command line or runtime? Where can i find linux radeon documentation?
