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 11.5 beta/preview release is said to have it. --Dtl131 07:54, 30 March 2011 (UTC) For more information, see: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/709505
WARNING: At the end of January 2011, Ubuntu integrated Xserver 1.10 into Ubuntu Natty/11.04. Even the most current release of Catalyst, 11-3, is not compatible with it, so Catalyst will not work if you have already installed Xserver 1.10. You can still use the open source driver until AMD releases a suitable version of Catalyst.
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).
