Linux

You can get the nvidia driver packages from the built-in repo.

pacman -S nvidia-dkms

should solve most of your problems

A lot of this stuff is already covered in the arch wiki, specifically challenging things like drivers. You should look into the documentation prior to asking.

I like how you're downvoting the people who are trying to help. I know I basically said RTFM in a nice way but that's the reality of the situation when you are working with Linux. You need to understand how to get this information from the documentation on your own rather than being reliant on other people to fill in the gaps.

Have you tried nvidia-inst?

Oh. Also, post the output of inxi -G

This will tell you whether or not the driver is installed, and which version. neofetch is useless for this task.

Like the other user said, this is all plain as day on the EndeavourOS wiki, but, I have something to add.

Seeing as how this is an Nvidia Optimus laptop, you will need a graphics switching utility to switch between, CPU, GPU, and Hybrid graphics modes.

The graphical way is to install optimus-manager and optimus-manager-qt. Once they are both installed, restart, and you will have a system tray icon that allows you to select your graphics mode.

The way I prefer, is to just use envycontrol, and do my graphics switching from the CLI. Mine stays connected to a monitor for gaming and is always plugged in when I’m using it, so I just set it to hardware acceleration and leave it. If I ever take it to the couch for non gaming activities I can always set it to hybrid mode with a simple command.

Again, this is all in the wiki.
