PowerMizer Power Source Error

  • Ubuntu 23.04
  • Surface Linux kernel (Issue happens on generic kernel as well)
  • Surface Laptop Studio (RTX 3050 Ti)

I’m having an issue where a short while boot up, the PowerMizer Power Source line in NVIDIA X Server Settings displays “Error” resulting in the GPU being stuck to the lowest clocks and a 10W power limit even when running a graphically demanding application using “prime-run”. Unplugging and replugging AC power doesn’t make a difference, the only way to resolve the problem is to reboot, where it’ll happen again after a little while.
