Couple of things.
You have an old optimus laptop with a Fermi family gpu.
With hybrid gpu setups like this the solution in Linux is either bumblebee or prime to utilize the nvidia gpu.
Firstly, your initially installed driver,
video-hybrid-intel-nouveau-bumblebee was depricated quite a while ago. Bumblebee doesn’t support nouveau, only proprietary nvidia drivers.
Your nvidia gpu, code GF117, is a Fermi family gpu. Unfortunately you cannot use bumblebee at all currently with a Fermi gpu.
Nvidia dropped support for Fermi gpus in their main driver, it is now in the 390 series legacy driver. Unfortunately Arch / Manjaro uses libglvnd and nvidia stated they are not backporting libglvnd support to their legacy drivers.
You could try it for yourself …
The intel gpu will work fine, but attempting to switch to the nvidia gpu via primusrun will cause an xorg error, as the nvidia driver doesn’t have correct libglvnd support.
So what does this mean?
You could just stick with using the intel gpu only. If your BIOS supports it you could use the nvidia gpu only (ie video-nvidia-390xx). Or you could try and get prime working with nouveau if hybrid graphics is important to you.
Not ideal, but this is what we get … nvidia treat Linux users like a red headed stepchild.
