I have NVIDIA GeForce GT520M graphics card on my laptop. Unfortunately I am unable to use it on my laptop running Ubuntu 14.04. I tried installing drivers from Settings>Additional Drivers.
But I am unable to succeed in that. After selecting the Proprietary driver from the list, as I click on "Apply changes", the progress bar moves a little bit and gets stuck there. I patiently waited for an hour, but nothing happened there after. Kindly help; I am unexperienced with Ubuntu.
Install nvidia drivers using command line, enter commands one by one.
sudo apt-get purge nvidia*
sudo dpkg-reconfigure lightdm
sudo apt-get install nvidia-331
This will also install Nvidia X Server settings, using it you will be able to choose what GPU to use.
You have a optimus GPU please uninstall the Nvidia driver and install Bumblebee and follow the instructions
sudo apt-get remove --purge nvidia-current
To install bumblebee in Ubuntu 14.04, run these commands in terminal
sudo apt-get install bumblebee bumblebee-nvidia primus nvidia-331
Now you have to install Bumblebee GUI to manage apps to be opened using nVidia. Here is the instructions:
Install Python App Indicator:
sudo apt-get install python-appindicator
Install Git:
sudo apt-get install git
Make a directory for git:
mkdir git && cd git
Check out the repository:
git clone https://github.com/Bumblebee-Project/bumblebee-ui.git
cd bumblebee-ui
sudo ./INSTALL
Go to Startup Applications and add bumblebee-indicator
Now reboot.
