This kind of switchable graphics called 'Optimus' (or in older Versions 'Bumblebee'). Here are some useful information, written by @Thanatermesis: Nvidia Optimus (intel + nvidia graphic card)
Since it is written in 'beta' I'm not sure, who exactly can access it. On the bottom of the article are some links for further information:
- NvidiaGraphicsDrivers/Optimus - Debian Wiki
- Bumblebee - Debian Wiki
- How To Make Nvidia Optimus Technology Work (properly) On Debian | Unixmen
- NVIDIA Optimus - ArchWiki
The third one looks very promising. I have only older versions of swichable graphics, so I can't provide any tips or hints by my own.
