Google is building its own DeX: First look at Android's Desktop Mode

Wish they would just adapt a full-featured Linux distro.

It seems to me the only difference between a phone with an extra screen, and a laptop with a SIM card, is the relative balance of power been the user and the vendor (Android restricts user capabilities for the benefit of Google).

How do we get back to the place where people expect a computer to have any number of peripherals, and be under the control of the user...?

https://plasma-mobile.org Does seem decent but the problem no major phone maker support it or make phones for it, in fact even linux desktop doesn't have may laptops/desktops "official" support,
