how do I mine with Nvidia and Amd cards on Ubuntu 16.04

[ale8803]

hello,

I started mining about a month ago, bought my first Nvidia cards and install drivers on Ubuntu, everything was working perfectly. Until I decided to buy AMD cards because of the crazy prices on Nvidia cards. As soon as I install the drivers of AMD and I reboot the computer I cannot longer log into the Os. I get this error "bbswitch: NO suitable _DMS call found" and goes back into the login screen. I'm new in mining and using linux. Can someone help me?

this is my set up
ASRock h110 pro btc
