I am currently using Ubuntu 16.04 LTS with an Nvidia Gforce 860M and recently found out that you can get the latest Nvidia drivers by using the graphics-drivers ppa. I feel dumb because everytime I've installed Ubuntu I've just used the stand three drivers to choose from and they are outdated. So I added the graphics drivers app to my system and wanted to know how would I install the newest driver? A new list of drivers appears in Additional drivers. I would like to install the 370.23 driver. Do I have to remove my current driver or does it do that automatically when I select that driver?
