I started by installing nvidia-current and nvidia-prime( I have no idea what this is. I read it online somewhere.Please tell me what it is :( ) and typed

sudo prime-select nvidia

and it gave me this 

Error: alternatives are not set up properly
Error: nvidia mode can't be enabled

I googled for the error and based on Michael's advice here , I typed this( again I have no idea about it).

root@PapaGolf:~# sudo update-alternatives --config x86_64-linux-gnu_gl_conf

Result Of Command

and again tried to switch to nvidia by

root@PapaGolf:~# prime-select nvidia

Now I'm stuck with

Error: %s does not support PRIME power management
Error: nvidia mode can't be enabled

I googled for this error as well but couldn't get anywhere. Can anyone help?

You installed a wrong driver for your adapter.

nvidia-current is a package for legacy cards.

You need to remove it and install the correct one:

sudo apt-get purge nvidia*
sudo apt-get install nvidia-346 nvidia-prime

prime-select should work after reboot.

These commands will install Nvidia driver version 346 for Ubuntu 14.04 and 15.04.

For Ubuntu 15.10 the commands will install driver version 352.
