So i'm helping my best friend to try instaling nvidia gtx 1050 mobile drivers on his laptop, we genualy don't know what to do and i can figure out how to make it work, curiously, neofetch detect it as a second gpu
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.
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.
