2008/3/30, Scott (angrykeyboarder) <geekboy@angrykeyboarder.com>:
I'm running Fedora 9 Beta i686.

When I attempt to enable desktop effects (System --> Preferences --->
Look & Feel ---> Desktop Effects). The box to enable them pops up, I
click "Enable Desktop Effects". The screen blanks out and is totally
white. It then returns after I hit the escape key (it took a bit to
figure that out) and I'm back to the "enable" box again.

At that point I just clicked "close".

No desktop effects.

$ sudo /sbin/lspci | grep nVidia
01:00.0 VGA compatible controller: nVidia Corporation NV40 [GeForce 6800
GT] (rev a1)

That card has 256MB of RAM. I've had no trouble with Compiz recently in
Betas of Mandriva or Ubuntu.

Is this a bug or a feature? ;)

Any ideas?

Curiously,

        Scott

Don't feel bad, at least you have X, my X disappeared entirely a few days ago - and I'm on the vernable free r200 driver. X is kinda.. featureful when it comes to not working at the moment.
