Ubuntu Mate 19.04 (personally using on live usb) and I believe the 19.10 alpha MicroPC build (personally not tried) works out of the box except touchscreen but the touchscreen fix is here
Just a quick update.
I have today flashed BIOS to v.0.24
I have then formatted the Ubuntu MATE alpha partition and reinstalled Ubuntu MATE Eoan (19.10 Beta)
Touchscreen works out of the box, a quick few minutes play and everything else seems to be working ok.
(Caveat, I have not had time to test power management / resume from standby / battery performance or fan noise tweaks)
