Hi, i got a problem i can't figure out how to fix.
I got 11.10 Oneiric (AMD 64) on a Lenovo s205 with AMD E-450, ATI HD 6320 Graphics and AMD Catalyst 11.8 driver.
The perfomance is not terrible but worse than the standard driver Ubuntu boots with before the proprietary ATI driver are installed. When dragging windows over the desktop they don't move smooth and wacthing videos in Totem Movie Player i get black frames every 3-4 seconds.
Also i got a "AMD Unsupported hardware" water mark in my lower right corner of my desktop the hole time. In Ubuntu "System Info" in Ubuntu system setting it repports graphics driver to be "VESA: Wrestler"
I tried the "ATI/AMD proprietary FGLRX graphics driver (post-release updates)" but it can't install.
The 11.9 driver from AMD installes but does not work with Unity, the launcher are missing.
If I remove the ATI/AMD proprietary FGLRX graphics driver, Unity launcher are again missing when restarting.

Why don't 11.9 driver from AMD work with Unity?
Why are the performance bad, is really smooth in win7?
