I followed this guide: http://www.illawarra.org/linux/index.php?id=howto
to install compiz-quinn and cgwd-themes. I am using ati x200 and have driver installed.

beside screenshot everything works fine. Any idea? doesnt matter much just I cannot show off my new eye candies and this is kind of annoying.
