I've recently installed xfce4 (switched from gnome3) as well as the Catalyst driver. I have quite a powerful computer along with quite a powerful graphics card (radeon 6950) however a lot of the features I want don't work. For example: terminal transparency does not work, and the mouse fragments sometimes when I move between monitors. I've been experimenting with the ATI control center settings, but nothing seems to fix this. I'd like to know if there are some optimisations I could look into (I already looked at the Catalyst page on the arch linux wiki) that would make my experience better. The reason I switched to catalyst from the opensource driver is so that I can run opencl apps, so the opensource driver is not an option.thank you!
