No fan under sensors (UX410UA, elementary OS 5 Juno, based on Ubuntu 18.04 LTS)

[xtelcz]

Hi, I am an absolute Linux beginner :-) Trying to get this work on my Asus UX410, but I cannot see any fan in sensors listing. Please, see my config below and get me any clue, how to make asus-fan works. Thank you!

Note: I have tried to do a standard install ubuntu_dkms_sudo_install.sh, but this not worked for me # modprobe asus_fan / modprobe: ERROR: could not insert 'asus_fan': No such device, so I have made a manual install, make, install, .... No secure boot on my notebook.

petr@UX410:~$ sudo modprobe asus_fan force_load=1
petr@UX410:~$ lsmod | grep asus

Well, this does not look very good, my guess would be that none of the implemented ACPI targets are actually in use within the zenbooks with the 8th generation, without such a laptop and currently I do not even have my UX32VD anymore, have plans getting one from this generation, but likely not before beginning of 2019... even then it might be a pretty hard job to go the loop again to reverse engineer what ASUS has done there... there is a perl tool in the repo which gives you alot of ACPI infos, you could use this before you do anything with asus-fan to see which acpi endpoints are actually changed during changing fan-speeds .... some more ppl have done this investigation, just check the other issues
