Hey again.
Just checked with 5.4.6 and the problem as described previously still exists.
And effectively idle system runs at ~75 °C even when just typing some text or switching some windows. Only if doing really absolutely nothing for a long time it may (but not always) go down to ~65 °C, which is still 5-10°C more than having the very same system (same software running, etc.) with a 5.2 kernel.
top still shows basically nothing.
I still suspect it could be somehow graphics related: - when I switch from the desktop environment to the kernel console, temperatures quickly go to ~60°C (which is more close to what's the case with 5.2)
- When doing some video playback, temperatures just explode (which they' don't with 5.2, of course they rise there as well). So when playing a video like mpv --vo=vaapi, CPU goes quickly to 90°C an more (and even when stopping playback, it stays at 80°C for minutes). Actually, sometimes (but not always) it was much better with --vo=xv.
The CPU is a Intel(R) Core(TM) i7-7600U CPU @ 2.80GHz, with HD Graphics 620 (Kaby Lake GT2).
Thanks, Chris.
Any ideas on what to do or how to somehow debug this?
Cheers, Chris.
