Switching Graphics in Pop!_OS Edit on GitHub

The following laptops have switchable graphics:

  • Oryx Pro (oryp4, oryp4-b, oryp5)
  • Gazelle (gaze14)
  • Adder Workstation (addw1)

Graphics modes

Intel

Intel graphics mode uses the integrated Intel GPU only and turns off the NVIDIA GPU. This mode uses less power, leading to a longer battery life and less fan noise.

NVIDIA

NVIDIA graphics mode uses the discrete NVIDIA GPU only. This provides a better graphical experience, but reduces battery life. Most external display ports on System76 laptops are connected to the NVIDIA GPU only. (Some models, such as the Gazelle, may also have external ports connected to the integrated GPU.)

Hybrid

Hybrid graphics mode uses both the integrated Intel GPU and the discrete NVIDIA GPU. Applications will use the integrated GPU unless explicitly requested to use the discrete GPU.

Switch graphics

Pop!_OS by System76 includes the system76-power package, which includes the ability to switch between Intel, NVIDIA, and hybrid graphics modes.

From GNOME Desktop

Click the system menu in the top right corner of your screen to access graphics switching.
