Are you using a rolling-release distro like Manjaro? It can be difficult to find and install the drivers you want.
If you can, try GitHub - Frogging-Family/nvidia-all: Nvidia driver latest to 396 series AIO installer
The following commands should help:
git clone https://github.com/Frogging-Family/nvidia-all.git
cd nvidia-all
makepkg -s
(you can use makepkg -si but I prefer doing a couple more commands)
Follow the prompt to choose if you want a specific version of 525, 530, 535, you can find the version you want with the following links:
Official Advanced Driver Search | NVIDIA (choose linux 64bit)
Releases · NVIDIA/open-gpu-kernel-modules · GitHub (these show additional releases but some are in the vulkan dev branch, not mainstream)
after makepkg -s, you have to do:
sudo pacman -U *.zst
To clean up the folder, I do:
mkdir tmp_zst
mv *.zst tmp_zst
After reboot, you should have the proper libraries for steam to launch and test the game.
