I am running a laptop with nvidia 8600m GT and have just upgraded to 8.04.
Desktop effects worked fine on 7.10 but now when I try to enable them in the appearances window I get an error 'The composite extension it not available'

I have searched around but all the info is either for ati or just says check xorg config.

I have checked in my xorg config and it says it is enabled in there:

Seems to be to do with my dual display. When I change dual display settings (either disable or turn of xinemara) the desktop effects work.

Is there no way of having dual head with xinemera and desktop effects?

On another note, my nvidia-settings seems to have broken slightly. Whenever I tell it to save to xconfig it tells me it can't. It seems not to ask me for my password when I start it up. I have to copy the xconfig from the preview manually to the file in order to change it. How can I fix that?

When I do have desktop effects enable on dual head without xinemera, I find that on my external display everything is very slow (click places tab and it takes 4-5 seconds for the list to appear) on my laptop display it is fine.

I have the same problem, it seems that composite extensions are not available in dual view.
Maybe I'm wrong, if someone knows anything about solving this problem please post here.

I'm having the same problem with 8.10 64 bit and my 8600GT...

It seems to me that as soon as I change to dual screen I can no longer have the effects, anytime before that I can.

Also, for some reason my xorg.conf isn't updating correctly. I had to manually put in the "Extensions" section just to see if it would work because it wasn't there, and anytime I had tried to save my settings with Nvidia X Server I had to edit it through the terminal...blah.

I believe if you use nvidia's "twinview" you can get composite on both screens, whereas if you use xorg's xinerama you cannot. I know I have used dual monitors with compiz on an nvidia card before, so it can be done. Do a quick search of the forums, I seem to recall some good threads that explain the difference between xinerama and twinview (and whatever ATI calls theirs).
