Thanks for the explanation. So is it due to the incorrect selection of
the graphics driver ? I have used F14 in the same hardware and was
able to enable desktop effects in GNOME-2. So I thought that GNOME-3
would work.

When I analysed /var/log/X.0.log I found the following lines:
[    33.188] (II) config/udev: Adding input device ImPS/2 Logitech

Does this has some relation to the issue I reported?
