So I just recently upgraded to Ubuntu 10.04 Lucid Lynx from 9.04, and there doesn't seem to be an easy way to enable 3D acceleration for my card (Mobility Radeon x600). On 9.04, i found a tutorial on how to downgrade xserver and a few other things to allow the fglrx driver to work properly. I haven't tried that method on 10.04 yet, but from what i understand, it wont work anyway.

So my question is, how can get 3D acceleration working? Is there any way to get it working under 10.04? The only other options i could think of were to either downgrade to Ubuntu 8.04, switch to Debian (i read somewhere that fglrx drivers for my card will work with Debian Lenny), or even dual boot Windows XP.

And if it makes any difference, I only want 3D acceleration support for gaming. Right now, the open source drivers seem to be working well for everything else (video playback, compiz etc)
