living xid-free life for 3 weeks, thanks to nvidia-smi patch AND lowering main memory speed. With generous lowest frequency of just 600Mhz - best possible at performance level 1, adding only 3W.
Now I have time to solve tons of other Linux problems, like disappearing bluetooth, hdmi audio, resume issues, USB3 acting like USB2 and many more. Since switched to Linux, only troubleshooting. I should’ve done myself a favor and go for Intel platform at least.
