Ubuntu Natty Installation Guide
From cchtml.com
Construction Notice
Since Ubuntu Natty/11.04 is still under construction, so is this page. Until Natty is released, the Maverick guide ( http://wiki.cchtml.com/index.php/Ubuntu_Maverick_Installation_Guide ) will serve as the main source of info on ATI Catalyst. This page will only note items that are relevant to Natty, but not Maverick.
Patching Catalyst 10-12 Source
Catalyst 10-12 needs patched for compliance with kernel version 2.6.37 before you can install it.

Catalyst and Unity
At this time, Catalyst doesn't work with the new Ubuntu desktop (Unity). You can still use the classic GNOME desktop (or another desktop environment).
