These by default will hijack your screen and run everything with the NVIDIA card. The NVIDIA control panel allows you to turn the GPU off completely.

Install `bumblebee` so the integrated graphics have priority and activate its service: `systemctl enable bumblebeed`.
You will need to add your user to the `bumblebee` group. Run `gpasswd -a yourusername bumblebee`.
To run programs with the NVIDIA card, run `optirun program`. For Steam games, change their executable command line to `optirun %command%`.
Finally, to allow the card to turn off completely when unused, install `bbswitch`.
> Even LESS laptops will like that. The workaround involves editing your kernel cmdline options to blacklist a little bit of Windows-specific BIOS code.
> Try adding `acpi_osi=! acpi_osi="Windows 2012"`. Try with 2009 or 2015 instead for 9xxm and 20xx series respectively if it doesn't work.
