I recently got my hands on an Asus Taichi 21 Ultrabook (see here).
Naturally I installed GNU/Linux (Linux MInt 19.3 in this case).
Everything works fine out of the box, except the touchscreen part (outside lid).
If I close the lid, the “Windows-Logo” outside gets bright for some seconds, then out. Nothing else. Linux Mint falls asleep, as on a “normal” notebook.
When I open the lid again, Linux Mint wakes up just normal.
I started an internet search and found only a few hints that sadly do not deliver any solution:
The second (touch) display is not recognized by LM at all:
There is a special key (the “Taichi-key”) on the keyboard, that switches from inner to outer display under Windows, but has no functionality when operated with GNU/Linux.
Surprisingly I can move the mouse on the inner display when touching the outer display…
Strange. There is just no graphics, but the “touchy” part is functional.

I checked the BIOS version too, it’s the latest for this model (211)
I also tried with Ubuntu 19.10, just the same.
Downloading Arch 2020.03 at the moment, to try with that, because one mentioned, that ist would work with that.
[Update] With Arch there is no touchscreen available, also…
Maybe someone has a hint to solve this.
Thanks, guys and greetings from germany. Stay healthy!
