4 years ago This will tell you if the NVIDIA card is being removed from the bus on startup:
journalctl --no-hostname -b -u system76-powerThis will tell you if it's currently on the bus:
system76-power graphics powerIn integrated mode, dynamic power management is not configured. So the device won't go into a low power state like in hybrid mode.
Unsupported discrete card vendor: 10de
The version of ubuntu-drivers-common you are using does not support render offload on AMD+NVIDIA systems.

My laptop configuration is Ryzen 7 3750H with an Nvidia GTX1660Ti MaxQ. I think the problem is that the Nvidia card is still running in the background. Attaching the gpu-manager.log while using Integrated mode.
Steps to reproduce (if you know): Switch to Integrated mode check usage on Powertop and then switch back to Hybrid mode and check Powertop again.
Expected behavior: The integrated mode should use less battery than Nvidia mode.
Other Notes: gpu-manager.log (Integrated mode)
