The desktop effects won't activate, even if they do

[qwerty800]

My desktop effects used to work.
They ALWAYS worked!
I'm on Karmic alpha 4.
I use the Nvidia propriatary drivers and, trying to help the nouveau project, I disabled the desktop effects and ran REnouveau.

And when I tried to re-enable the effects (I hadn't even restarted my computer or updated anything), it told me that it wasn't possible!

But what's the weirdest is that, when the computer try to enable the effects, THEY DO enable themselves for like 2 seconds, AND if I close the window during these two seconds, the desktop effects do remains, but I end up with Xorg taking half of my processors.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers.

Hi qwerty8034,

Please attach the output of `lspci -vvnn` and `dmesg`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you're using a custom /etc/X11/xorg.conf please attach that as well.

This is certainly not an xserver-xorg-video-nouveau bug; the reporter
says that desktop-effects activate :).

It sounds like it's probably a gnome-control-center bug; that's where
the Appearance capplet lives.

Could you please attach your Xorg.conf as suggested by the automated
message; that could potentially be interesting.

Could you also attach the output of running "compiz --replace" in a
terminal. This will allow us to determine whether the problem is compiz
or in the desktop-effects enabling logic.

Right. That Compiz output looks right, suggesting that this is a
gnome-control-center bug. Can you run "apport-collect -p
gnome-control-center 421307" to collect the standard details. Also, the
output of running "gnome-appearance-properties" in the terminal and
trying to enable desktop-effects might be interesting.
