Hi,
as I write in more threads here and there on TechTablets, with little experience and effort , you should be able to install and run Linux on EzB 3 Pro.
And on my version 2 (M.2 slot present, without ac wifi), wifi works with custom driver, touchpad works with like 3 commands in terminal, audio works out of the box, special Fn+ keys work out of the box. Card reader works out of the box. Bluetooth doesn’t work, but I live happily without it, but I think it should be possible to make it run, I just didn’t dig deeper, because it wasn’t my priority.
I installed Lubuntu, and after some time I hopped onto Manjaro bandwagon. I use Xface desktop now. Dualboot with factory Win 10.
Check my thread on LinuxQuestions, that should help you or ask here, what I know, I ‘ll be glad to share.
good luck,
U.
