Thanks for that, installed and tried various options, all is working OK re OpenGL etc. As a test I created a new "test" account and logged into that, enabled desktop effects and they worked :) So I need to find the offending setting in some rc file I guess in my normal /home DIR or possibly a Widget is the cause (doubtful) This was a clean install however I did copy over quite a lot from my backup of Home from F11, so a little misleading and obviously something has caused this problem. I really appreciate all the help and assistance I have had here, Cheers Colin -- Fedora release 12 (Constantine) Registered Linux user number #342953
