I had three initial problems running openSUSE 11.1 in my system. First I have a motherboard with full SLI (not soft SLI), 4G of RAM, an AMD dual core processor and two Nvidia cards with 7300GS video chips.
The following problems occurred:

2) I could not get Compiz with Emerald to work or even try to work.
3) My virtual machines would not run.
The fix:
1) The openSUSE kernel (maybe?) loses...
