[gentoo-user] radeon screen resolution

[john]

Hello,

I have installed Gentoo on to another partition in order to use radeon
drivers for desktop instead of fglrx.

When I start my resolution is very small (1280x600) and only uses half
the screen. My max resolution is 1920*1080 so I have a big black border
around my screen. I can startx which works but cannot change the
resolution to anything bigger. GRUB splash uses full screen but when the
kernel loads it switches to small resolution.

The only thing I can think of which is causing this issue is UEFI. In
my other set (fglrx) up I have simple framebuffer enabled which works
when I set up resolution in grub default.

Strangely enough when I start system rescue cd in UEFI mode I get the
same problem with small resolution but not if I do not boot in UEFI
mode.

Anyone come across this or got this to work properly with radeon/UEFI?

Moral, don't use UEFI I guess but that's the future???????!!!!!!
