Meanwhile, I tested the GNURoot Debian + XServer XSDL solution
(
https://www.xda-developers.com/guide...ndroid-device/ )
although not on the Max2, in order to avoid putting it on the Internet (creating firewalls etc.).
As one would guess, it works - I am sure it will also work pretty well on the Max2. I still have that VNC feel (the client is embedded in GNURoot Debian, I think)... And I believe all those layers (desktop Linux running above Android) have a performance impact.
But it is probably viable, if one needs a desktop application to run and cannot connect the tablet to other devices.
Sogaiu, what was your experience - mostly in terms of the usability related to speed? If I have to pick an application, as you probably imagine, I would say LibreOffice.
