open source ATI drivers not working

Default Ubuntu 10.10 install.

system info -> graphics -> driver says "unknown" and experiece : 'standard'
Hardware -> additional drivers : totally empty.
Windows are moving around sorta slow.
lspci | grep VGA

01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series]

What's wrong. Why doesn't additional drivers show propertietary ATI driver? And why is there driver : "unknown"

Can somebody help me to troubleshoot this one...

Solution 1:

Find your driver here: http://support.amd.com/us/gpudownload/Pages/index.aspx

Once you download it, install it:

sudo sh 'path/to/file/drivers.sh'

After it is done installing, type into terminal:

sudo aticonfig --initial

Then restart and it should work!
