I have Lubuntu64 LTS on a GPD WIN 1 ver 2 (z8750). Fresh install, no tweaks. On the login screen, it runs the cooling fan on full speed, but when I log in, it stops the fan immediately. It was OK to this point, but it stops the fan forever — on heavy tasks, thermal sensors show "red" >80°C, and it does not run the fan again.
If I log out, the fan runs again.
Looks like a default fan manager is loaded with the user environment, but it works incorrectly. What fan managers Lubuntu can have by default and how to configure/disable them? They seem to override the hardware fan switch on the GPD's rear side. If I remember correctly, older versions of Lubuntu didn't mess with the fan, leaving the hardware switch doing it's job.
According to Synaptic, nothing related to "fan", "speed", "fan control" etc. is currently installed.
BTW Lubuntu+GPD1.2=awesomeness (except this problem).
Update: I've installed LTS 20 (with LXQT) and it works the same way. On the login screen, the hardware switch controls the fan as it should. When I log in, power manager overrides the switch and stops the fan. Is there a way to uninstall the software fan control in Lubuntu? Hardware switch is OK for me, and it's way better than software control working the wrong way.
