Just a quick follow up on this
Have this evening upgraded my notebook to Ubuntu Jaunty and was unable
to activate compositing.
> https://bugs.launchpad.net/ubuntu/jaunty/+source/xserver-xorg-video-intel/+bug/36382 explains
The solution for me was to add SKIP_CHECKS=yes to
Acer Aspire 5720
Hope this helps someone
A similar problem also appears to exist with some Intel chipsets too. I
tried the release candidate on my Acer note book with similar results.
Haven't had an opportunity to try the final release yet but will comment
agin when I have if the problem still exists.
Have a good day all
