Mixxx has worked for me before with older versions of Catalyst (10.7) in Linux Mint 9, using compositing (Compiz in Gnome).
After changing to Ubuntu Maverick and Catalyst 10.10, it it crashes the complete system if compositing is enabled, but it works without issues if I disable it.
All this is in a Dell Studio 1535 notebook, with ATI Radeon Mobility HD 3400.
