I am trying to install the driver on my asus n551jq, under ubuntu 14.04.02 lts.
My steps are:
sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install nvidia-337
However, for the third step I get
E: Unable to locate package nvidia-337
As an alternative solution, I downloaded from nvidia website the driver NVIDIA-Linux-x86_64-337.25.run,
alt+ctrl+F1
I run
sudo service lightdm stop
sudo sh NVIDIA-Linux-x86_64-337.25.run
After the installation, I type:
sudo service lightdm start
And a window appears with the message: "the system is running in low-graphics mode. Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself.".
From this point on, it is not possible to enter to Ubuntu.
