Problem with nvidia 820m

Question

I have laptop asus X455ld with core i3 and I installed Ubuntu 14.04. However, I can't switch to nvidia 820m graphic card. How can I resolve this problem?

Answer 1

I have same laptop as yours. I installed Nvidia drivers successfully. If possible check whether your system is 32-bit or 64-bit and after installation don't start the lightdm service.

Open the terminal and run the following commands:

sudo service lightdm stop 
sudo init 3
sudo chmod +x <file_name>.run
sudo sh <file_name>.run
sudo apt-get update
sudo apt-get upgrade
sudo service lightdm start
sudo reboot

If it's not working, then try reinstalling your desktop environment.
