I’m Using Debian 9 Buster. I installed the Nvidia drivers from Debian non-free repository. I noticed that I only using 2D graphics and 3D is not working. I googled some and find that I could get 3D to work if i remove xorg.conf and it did. I could be happy with that but I want to use “Force Composition Pipeline” to remove tearing. This setting should be set in xorg.conf if you want it to be permanent.
Is the xorg.conf no longer being used or is there another problem?
