Ok, thanks to all of you, everything works ![]()
If another EOS adventurer found this topic, I have done the following :
- understood very lately that some packages exist on another repo than arch
- installed
nvidia-instviasudo pacman -S nvidia-instand runnvidia-inst - installed
nvidia-hookvia the same way and run it, but, in fact,nvidia-instseem to have already done the stuff to rebuild - reboot
- installed
envycontrolviayay -S envycontrol(this is a personal choice,optimus managerwork too) - setup this stuff to use only my nvidia GPU with
sudo envycontrol -s nvidia(personal choice, as well) - and voilà
