I haven't had any success with the nvidia drivers to use UI2. The first time I installed LinuxMCE, I already had the Automatix2 nVidia drivers installed, and it looked great, dual monitors working with max resolution, but I wanted UI2 with alpha blending. So I set out on a journey to get it working!
I'm on my 9th install of Kubuntu/LinuxMCE. Each time I install LinuxMCE, I start with a fresh copy of Kubuntu. I might want to ghost this partition soon if this is going to be many more times before I get it working.
Anywho, I took the necessary steps that Kurt suggested, installing the latest Nvidia drivers from their website. When I reboot, it just sits at a black window with a flashing cursor. So I hit Ctrl+Alt+F1 to get to another console, and I restore my xorg.conf, startx, and voila, I'm back in.
Then I did some comparing of the xorg.conf that failed and the xorg.conf that was good. The only difference was:
Non-Working xorg.conf: Did not contain DRI; used nvidia driver; did not specify BusID under "Device" heading
Working xorg.conf: Contained DRI; used vesa driver; specified a BusID under the "Device" heading: BusID "PCI:1:0:0"Click here to view working [vesa driver] xorg.confClick here to view non-working [nvidia driver] xorg.conf
Now when I try to modify just that driver line to say "nvidia", then I type "startx" it results in:Click here to view non-working [nvidia driver] startx log
When I change it back to "vesa" and then type "startx" it results in:Click here to view working [vesa driver] startx log
And finally, my lshwd -id output:

Most people would give up after 3 bad installs...but not me. I went out and bought a 42" 1080p LCD just so I could have a decent TV for LinuxMCE. It wasn't until the 4th of 5th install that I actually got to see the LinuxMCE interface running.
Any advice/help is very much appreciated.
