I have a two video cards unfortunately they aren't the same, one is Nvidia the other is ATI so that makes it more difficult ...
System can see both cards here is my lspci:
What is good way to make all of them work ? I have seen lot of info on the web but they all lack how to do it another words there is not good guide or documentation out there ...
I tried configuration with open source driver and with nvidia proprietary driver as well but no luck whatsoever
P.s two monitor works out of box can't get third one working though
