Comment 0 for bug 279762

I am using the Intrepid Ibex prerelease (fully up to date as at 7 Oct 2008). My laptop is a Gateway M-Series, with a Core 2 Duo...and an ATI Mobility Radeon HD 2600 graphics card.

When I attempt to enable desktop effects, I get a message that "Desktop effects could not be enabled." My xorg.conf file follows:
