Im new on linux, when I decided to change KDE to XFCE, XFCE doesnt recognize my GPU(it shows “GPU: Unknown”).
On archwiki i saw that recommended driver for my GPU is nvidia-open, but EOS installed nvidia by default.
I need just use “pacman -Rs nvidia” and then “pacman -S nvidia-open” or it more complex than that?
Use nvidia-inst
Run nvidia-inst --test to see what it will do and nvidia-inst to actually do the work. Add the --32 option if you need 32 bit libs for gaming.

          That should work.
There’s a tool nvidia-inst that should help you see the packages needed and it can also install them if you wish.
For example, try nvidia-inst --test
More details: nvidia --help

          use instead both commands, or “pacman -S nvidia-open”?
Instead of both. It will remove the closed drivers and install the open ones, if your graphics card supports it, which is the advantage over doing it manually. I see your card does support the open drivers, so the manual way will work too.
