I've looked around, but haven't found a solution that works for me to get the nvidia proprietary drivers working. I'm running Ubuntu 13.10 and have a GTX 680 graphics card.
I've tried the following:
sudo apt-get install nvidia-current
Result: When I reboot the machine I just get a black screen. If I ctrl+alt+f-whatever to a different tty panel I just get a blinking cursor and can't type or do anything.
I reinstalled ubuntu and then tried this:
sudo apt-get update sudo apt-get upgrade sudo apt-get install linux-source sudo apt-get install linux-headers-generic sudo apt-get install nvidia-current
Same result as above.
Finally I just tried installing it from the restricted drivers tab, but it just tells me there are no drivers available after searching for a few seconds.
