Hi again, I posted here earlier because I was unable to build i3-gaps due to a missing package. That was fixed, however there is still something wrong with my Nvidia drivers or settings.
I went on to install compton, but when I try to run it I get an error:
$ compton -b
glx_init(): No GLX extension.Xorg log errors:

My /etc/X11/xorg.conf is currently empty, as that allows me to at least start X but I'm guessing it's using the intel part of the videocard. The NVIDIA Optimus page says to add the following but then I just get a black screen.

Have you configured a display setup script if you are using a display manager or added the xrandr lines to ~/.xinitrc?

Not using a display manager here, but I hadn't added those xrandr lines to ~/.xinitrc. My bad, the way that section on the wiki is ordered made me think those lines are only necessary on the older version of Xorg.
Case closed, thanks again loqs.
