Automatic nvidia driver installer for Arch Linux with optimus-switch-qt
It sets up Pamac AUR helper for optimus-manager-qt
To properly install everything, make sure that you've removed your existing prime/bumblebee setup or your xorg server would most likley to crash. I don't take any responsibility for anything (Nvidia drivers are really rough -_-) so do everything at your own.
Go to the directory and inside, type: sudo chmod +x start.sh
it will make start file executable.
When everything is setted up open optimus manager setting at the little icon and import optimus-manager-qt.conf file whitch is included inside your zip file
Make sure to check "start this program at the startup" at the settings.
reboot
enjoy :)
