Problems installing Nvidia drivers
What is the expected or accepted way to install nvidia drivers now that Additional Drivers is not installed by default in 12.10? Not sure what changed for the worse in 12.10 graphics, but default nouveau is very sluggish compared with previous versions and results in colored snow (even in just a terminal) if I try to scroll windows unless something else refreshes the screen. My nvidia card is not really new or really old.
Since the powers at Ubuntu have been pushing their Software Center instead of the usual tools (Additional Drivers or Synaptic), I tried Software Center for installing nvidia current, but that totally messed up X after reboot. All I get after gui login is the background image with nothing else. I am able to open a terminal with Ctrl+T, but that is all. And if I go to a console with Ctrl+Alt+F1, once I login and try to stop lightdm all of the consoles disappear (cannot get to them anymore) and I am left on a black screen. But if I move the cursor around, the login screen repaints like an Etch-A-Sketch and I am actually on the gui login screen.
I tried doing nvidia-xconfig from a root console in recovery mode (after remounting the drive read-write) and all that did was make the screen lower resolution with huge fonts in the login gui. Still no X apps after login, just background image.

But that did not work. Apparently nouveau and nvidia do not cooperate like they do in 12.04, so X ends up unable to load any nvidia modules.
I am just glad I did not trash my perfectly working 12.04 system by upgrading it to 12.10, or I would have been really upset.
