I am running LG Gram 16Z90Q (Intel I5) with PopOS and kernel 6.0.6 and I
don't have this issue. Battery lasts half a day, it does not get hot
whether plugged in or not. I had stability issues with Ubuntu, although I
was running the newest release, not the LTS version and I did not have much
time to dig into what is causing it. Then I figured System76 guys are
building OS for laptops so maybe they already did the necessary tricks. And
I fell in love with their tiling windows manager.
The only things that do not work are fingerprint reader and the screen
brightness buttons (they work with huge lag).
