I tried to update the nvidia drivers using:
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current
After this, I rebooted my pc, launch Ubuntu, then I can see that it's loading everything (as usual), but then I end up with a black screen and a flashing underscore. (I tried to load the terminal at this point using ctrl + alt + F1, but that doesn't work)
My videocard model is GT650M
How can I fix this?
