Hello, I have a problem, I have 2 graphics cards (GTX 1050 and GT 640) and I want to connect a screen to each card because the GT 640 has a VGA port for my screen and for performance reasons so I read that I had to use Xinerama but when I activate it on the nvidia panel and restart my Xorg crash computer.


my xorg.conf:
