Recently I installed Ubuntu on my new system which has a Nvidia graphics card. After installing Ubuntu 12.04, I felt that the screen resolution was not good and though it was maybe because the Nvidia drivers were not installed, so I tried to install the driver using the following commands:
sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current
After installation I restarted my system. Upon restarting, the system hangs on a screen which displays Nvidia logo and does not proceed. Can someone help me?
