Sapphire HD6870 on Ubuntu 11.10

Hi,

Had anyone here have any success getting Radeon HD6870 running well in Ubuntu 11.10? (Smoothly)

what exactly is the issue? Are you using opensource xorg drivers, or the FGLRX ati/amd driver? Your card is definitively supported by the former...

I had actually tried using both but none of them works well. The display does work but it doesn't run smoothly as compared to nvidia and intel onboard graphics that I have.

screen tearing?
if so then enable anti-tearing in the amd config tool and set vsync in compiz (make sure 'sync to vblank' is checked):
