Unable to use Nvidia GPU (Optimus Manager) in Linux 5.10.3-arch1-1 and below

In the log files for Optimus manager above, the version indicated is 3.9. Running “python -V” told me it’s version 3.9.1.

Meanwhile, I’ve tried downgrading my kernels further, and for all cases below so far, the GPU isn’t working:

  • 5.9.10.arch1-1-x86_64
  • 5.9.11.arch2-1-x86_64
  • 5.9.12.arch1-1-x86_64
  • 5.9.13.arch1-1-x86_64
  • 5.8.14.arch1-1-x86_64
  • 5.7.12.arch1-1-x86_64

Will keep trying to downgrade and report back my findings by editing the list above. Edit: 5.7 is my oldest kernel in my pacman cache, and I don’t think downgrading the kernel helps at this point.

The funny part is, my GPU has always been working even through all of the above mentioned kernels. Now, they no longer work except for the latest 5.10.3, but then my audio breaks…

Additionally, I’ll try 5.9.14 again and maybe reinstall optimus-manager instead? Could be more useful than blindly downgrading. Edit: Tried this through “yay” with Cleanbuild, but doesn’t work.
