I've tried to install the nvidia drivers on my Arch Linux / Antergos laptop, since I noticed it has been using the built-in Intel HD Graphics. The graphics card in question is a NVIDIA GeForce 940MX.

Here's what happened when I tried to make things work:

sudo pacman -S nvidia nvidia-utils lib32-nvidia-utils nvidia-settings
sudo nvidia-xconfig
(reboot right here)
(find that screen goes black and the backlight off when I switch to TTY7 / x)
(switch to tty2)
sudo modprobe nvidia
(no output, things still don't work)
sudo prime-select nvidia
(apparently prime-select doesn't exist on my system for some reason
despite having nvidia-settings)
sudo pacman -R nvidia
sudo mv /etc/X11/xorg.conf.nvidia-xconfig-original /etc/X11/xorg.conf
(reboot right here)
(back to normal, still on Intel Graphics Card)

Could someone tell me how to make these drivers actually work? I had them working on Ubuntu prior to this (as a last-resort after the last time I tried making them work on Arch/Antergos.)

Edit: I've got it working using optirun/primusrun and bumblebee, but I'd really prefer to just use it for everything, as I prefer quality over power management.

I've had black screen issues with these drivers before (using GTX 980 Ti, Arch Linux with latest everything and HDMI output). My findings from this week:

  • The Nouveau drivers work, but I couldn't get them to do 4K at 60 Hz, unlike the proprietary drivers (might well be my fault, though). If you require less than that, I would simply follow their instructions and forget about the proprietary driver.
  • The proprietary drivers work again after removing /etc/X11/xorg.conf and every trace of Nouveau. However, I am having issues with what appears to be the HDMI interface going "offline" for about a second randomly while watching full-screen video. This may or may not be related to the earlier issue.
