I tried to install using the documentation found here (https://wiki.archlinux.org/index.php/Bumblebee), but when running:

optirun glxgears -info

I get this output:

[  309.531594] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) Failed to load module "nouveau" (module does not exist, 0)
[  309.531645] [ERROR]Aborting because fallback start is disabled.

I have two video cards: one integrated from Intel and a dedicated GeForce GTX 960M.

The output of inxi -G:

    Graphics:
      Device-1: Intel HD Graphics 530 driver: i915 v: kernel 
      Device-2: NVIDIA GM107M [GeForce GTX 960M] driver: nouveau v: kernel

    Please edit your question and show us the output of inxi -G (it's on AUR if you don't have it installed) or, at least which drivers you have installed for the card. Are you using the nouveau open source drivers? The proprietary nvidia? The error suggests your system is looking for nouveau but can't find it. Have you gone through wiki.archlinux.org/index.php/Nouveau? – terdon May 30 '19 at 18:02
  • lspci -v is an easy way to list the drivers you are using - search the output for your video controllers, looking at the "Kernel driver in use" and "Kernel modules" lines. lspci is most likely installed. – fra-san May 30 '19 at 18:47
  • @terdon Post updated with the output of inxi -G – Alex May 30 '19 at 22:13
  • @fra-san Also added the output of lspci -v – Alex May 30 '19 at 22:20
