I recently switched to Ubuntu 18.04, and had a lot of problems but managed to fix most. I am using a laptop with an i5-7200U and an NVidia GTX950M. I have installed the latest drivers, wine games work just fine.
The thing is: I don't know which graphic card is used in the system, whether it is the integrated one or the dedicated, and I have A LOT of screen tearing while moving things around while scrolling on the browser etc.
Is there a way to force enable vsync or fix the tearing otherwise?

As requested by David, here is the result of the first command:

Try the instructions here. The quick fix worked well. It was night and day. All I had to do was copy and paste a command into the terminal, but the permanent didn't work. I couldn't make a xorg.conf file.
