desktop effects could not be enabled

I have just installed FC6, and when i run "desktop-effects" in command line, I got the reply "desktop effects could not be enabled". and the code is [root@localhost ~]# desktop-effects
gnome-window-decorator: Screen 0 on display ":0.0" already has a decoration manager; try using the --replace option to replace the current decoration manager.
compiz: GLX_SGIX_fbconfig is missing
compiz: Failed to manage screen: 0
compiz: No managable screens found on display :0.0

have you tried the command:
desktop-effects --replace
as suggested in your error message.

EDIT: also check out this thread

How about enabling them as a normal user and not root. I think there is a menu entry somewhere that allows you to do this.

I'm a bit of a newbie too, but does your graphics card support the kind of effects you're trying to enable?

gfx card

well it's an ati 128 mb, looked smashing on windows. I'm pretty sure that it could handle the piddly little demands on compiz.

have you installed the ATI drivers from their website or are you just using the default drivers that come with FC6?
