I installed nvidia-lts and ran sudo nvidia-xconfig hoping that it will make the Nvidia drivers work, but it created a config file in /etc/X11/xorg.conf which prevented me from launching X with startx.

I am using Antergos Linux now.

I could get the Nvidia Driver to work when I was using Ubuntu just by installing a package from the repos.

How can I get the Nvidia Driver to work?
