For longer battery life and a quieter laptop use Intel graphics and switch to NVIDIA graphics when you need additional performance or to use external displays on certain laptops. External display ports are connecting the the NVIDIA GPU on System76 laptops.
Currently the only laptop that supports this feature is the Oryx Pro (oryp4).
Pop!_OS by System76 includes the system76-power package that includes the ability to switch between NVIDIA and Intel graphics.
Click the system menu in the top right corner of your screen to access graphics switching.
Select either NVIDIA or Intel depending on which GPU you would like to use.
Once you select either NVIDIA or Intel you will be prompted to reboot.
If you are not on the GNOME Desktop Environment there is a command line option to use system76-power. You can see these options with this command:
For seeing which Graphics the system is using:
sudo system76-power graphics
For switching to NVIDIA Graphics:
sudo system76-power graphics nvidia
For switching to Intel Graphics:
sudo system76-power graphics intel
