Re: 64 bit vs. 32 bit Ubuntu 12.10 Compiz stability question
One source I read said you also needed linux-source, but maybe not really. But if you have already installed nvidia-current with everything related (I installed it from Software Center) and it does not work, you don't really need to "uninstall" nvidia drivers. You can add the kernel headers and "reinstall" nvidia-current or whatever version you need
Once you reboot after that, everything should fall into place.
sudo apt-get install linux-headers-generic
sudo apt-get --reinstall install nvidia-current
Not exactly newbie friendly, but I guess if they stick with it, they can learn something new.
