Ubuntu Natty Installation Guide
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.
Xserver 1.10 Incompatibility Warning
(This section to be removed once Catalyst supports Xserver 1.10) Hopefully, AMD will integrate support for the new Xserver before Natty's release. The Catalyst 11.3 beta is said to have it. --Dtl131 21:00, 29 January 2011 (UTC)
WARNING: At the end of January 2011, Ubuntu integrated Xserver 1.10 into Ubuntu Natty/11.04. Even the most current release of Catalyst, 11-2, is not compatible with it, so Catalyst will not work if you have already installed Xserver 1.10. If you have not yet installed it, and want to run Catalyst on your Natty/11.04 install, you can hold the Xserver packages (or "Lock Version" as Synaptic refers to it) and continue to run Catalyst 10-12.
Patching Catalyst 10-12 Source
(This section to be removed once Catalyst supports Xserver 1.10) 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).
