Issue/Bug Description:

System76 Power doesn't work properly on mainline kernels 5.11.17 and higher. Works fine on 5.11.16

• personally tested this with mainline kernels 5.11.17, 5.11.19, and 5.12.2.
• 5.11.16 and lower all worked fine for me

Steps to reproduce (if you know):

1. update kernel to mainline 5.11.17 or higher
2. select Hybrid Graphics option via System76 Power
3. reboot machine
4. System76 Power is stuck on Integrated Graphics after reboot.
5. right click + Launch using Discrete Graphics Card option is missing

Expected behavior:

• System76 Power properly changes between integrated, hybrid, etc
• right click + Launch using Discrete Graphics Card option is present and working

On what kind of system was this replicated?

On what kind of system was this replicated?

This is on an ASUS Zephyrus G15 laptop with Ryzen 5900hs + NVIDIA GTX 3060. link

This isn't a System76 laptop, so I'm not really expecting any support, just reporting the bug.

Ah, just realized that I should've probably posted the issue at https://github.com/pop-os/system76-power instead
