I recently upgraded to 12.10. In the process, my laptop, which is a W520 in a dock, connected to 2 external monitors (the same monitors.. Dell U2400). I finally got the nvidia-experimental-310 driver working with both monitors. Everything was glorious for a few weeks, and then the thing decided to upgrade the kernel and I didn't realize it did that when I asked it to do the apt-get upgrade.
After realizing my mistake, I went back and tried reinstalling the nvidia driver, since I assumed it needed to be built against the current kernel again. I couldn't get either the nvidia-current or nvidia-experimental-310 drivers working (they booted into a black screen with a flashing cursor, or, in the case of the 310 driver, wouldn't let me enable my second screen).
I was able to get the nvidia-experimental-304 driver working, though. So, after some trial and error, I updated my xorg.conf file and rebooted. Now, however, I get the following error in my Xorg.0.log file:
[ 16.023] (EE) Failed to load module "nvidia-experimental-304" (module does not exist, 0)
But, when I go to a virtual terminal, and run the following:
# modprobe nvidia-experimental-304
# /etc/init.d/lightdm restart
Everything now works as expected, except that the following still shows up in my Xorg.0.log file, even when X starts as I would expect it to:
[ 16.023] (EE) Failed to load module "nvidia-experimental-304" (module does not exist, 0)
Can anyone tell me what I'm doing incorrectly? I'd like to get the module to automatically load on startup, so I can boot into X directly, without having to manually modprobe the module.
My xorg.conf file follows.
Edit
If I change the Driver "nvidia-experimental-304" to "nvidia" in my xorg.conf file, the system runs in low-graphics mode on reboot, with the following errors in the xorg.conf file:
[ 17.147] (**) NVIDIA(0): Enabling 2D acceleration
[ 17.163] (EE) NVIDIA(0): Failed to initialize the NVIDIA kernel module. Please see the
[ 17.163] (EE) NVIDIA(0): system's kernel log for additional error messages and

[ 17.163] (EE) NVIDIA(0): *** Aborting ***
[ 17.163] (EE) NVIDIA(0): Failing initialization of X screen 0
syslog now shows:
