OK, installed the drivers, the hardware drivers thing said that they were in use, went into nvidia X Server Settings, said to run nvidia-xconfig as root and restart the X server. Did that, rebooted, and now it gives me crap about errors and running in low-graphics mode before the login screen.
EDIT: Went into the Hardware Drivers thing, it says they are active and currently in use.
