Hi, Out of curiosity, I am using rpmfusions Nvidia drivers but I can't get any of KDE's desktop effects to work, everything else seems fine. Is this a known problem? All was fine in F11, I've tried to search for some info but no luck so far. Clean install - F12/KDE-4.3.4 Cheers Colin -- Fedora release 12 (Constantine) Registered Linux user number #342953
