@jaap @sonny @leledumbo i actually managed to run Manjaro 23.1.4 GNOME perfectly, keyboard & touchpad working, all FN keys too, touchscreen - all without problems. Autorotation is not working, as expected, but its not a deal breaker at least.
All i had to do is stupid BIOS update. Now im running 2.19 which i got from here. Screen issue is still present on this version, at least in Debian derivatives, however in Manjaro and, probably, Fedora 40, as it was before, no issues was found. So, now this little boy would be my main machine which i would use to access my VMs and doing AR stuff. And yes, type-c does support at least Rokid Air AR glasses, which was also huge deal for me.
I will try to contribute my attepmts at refining this notebook, though, if i will discover anything else. Until then, have a great day!
