Hello Alex

When using the ati-driver neither the default mode nor 1600x1200 work, I
haven't tried other modes than those two.
Trying to change the resolution using Ubuntu's built-in graphical tool
(gnome-display-properties) doesn't work. When I choose a different resolution
and press Apply I get corrupted colors (I've attached a picture that shows how
it looks). Getting to a console and restarting gdm fixes this issue with
corrupted colors. I'm not sure if it's relevant but I figured it could be.

You'll have to guide me on how to compile avivotool from source. I've tried
getting the source with git but it contains no README file or anything so I'm a
bit lost.

I'm also not sure what or how to compile, as you say, "ati driver from git
master". But if you can tell me how to or just give me a link that explains it
I'll definitely try it.
