I need to add additional drivers. In software sources I see:
- Official repositories
- Additional repositories
- Authentication keys
OS: Linux Mint 17.3
The question is:
How do I install proprietary Nvidia driver?
The official way:
Click Menu -> Driver Manager -> enter your password.
nvidia-340 or whatever version currently official is.
Click Apply changes, and wait for it to finish.
Click Reboot to restart the machine.
The unofficial way: I can't recommend it, since I had multiple issues with these drivers myself, but it is entirely up to you and your needs:
Add a PPA to your system, from terminal, you will be asked for password:
sudo add-apt-repository ppa:graphics-drivers/ppa
Press Enter for it to finish.
In the terminal type and confirm:
sudo apt-get update
Proceed from step 1 from The official way, select the version that suites you best.
