I've tried the 64bit version and found I was constantly hitting a brick wall trying to get 32bit stuff to run; I'd previously used PAE on 9.04 without any issues so figured I'd give it a shot.

However, on 9.10 it seems PAE or the process of enabling PAE breaks the nvidia drivers/module somewhat as performance is terrible; I can't even enable desktop effects and there's lots of artifacting on random controls.

Disabling the pae image and rebooting fixes the issue however I'm then stuck with "only" 2.7Gb of ram and unable to use the full 8gb that's installed.

Is there somthing special I need to do when using pae and nVidia drivers or should I be using 64bit and just figure out how to force run 32bit packages? :-p
