Ubuntu 11.10 desktop fails to load with Xinerama/Nvidia
I hope this is the right forum for this question:
I have a fresh install of Ubuntu 11.10 on a 64 bit AMD machine with an Nvidia 460 graphics card. I'd like to run dual monitors using Xinerama. The initial install went without a hitch but now I can't enable Xinerama through Nvidia X server settings without losing my desktop. After enabling Xinerama the login screen loads and accepts my password and I get my wallpaper displayed on both monitors and a responsive mouse cursor across all displayable real estate, but that's it. No launcher appears and keyboard inputs are ignored. I've included my current xorg.conf, with Xinerama set to "0" so I can run my desktop. I hope someone here can provide me with some insight.
Try making a new xorg.conf with the nvidia-xconfig utility. Here is my xorg.conf, generated with that utility, that is working for two monitors with Xinerama.

Running nvidia-xconfig helped a little, but I still can't use the second monitor. THe cursor "X"s out when I move over it, and now my keyboard input lag has increased to an intolerable degree. Here's the xorg.conf that I have now:
