Maemo Leste is community a Debian/Devuan based GNU/Linux distribution for smartphones and tablets aimed at free software hackers. In spirit and look it is similar to the Maemo Fremantle OS for the famous Nokia N900 phone. This talk will present the current (alpha) state of Maemo Leste, the presently supported devices, our development setups, the present and upcoming challenges and lay out the future plans for software and hardware (device) support. This lecture will introduce Maemo Leste, a free Debian/Devuan based GNU/Linux hacker distribution for smartphones and tablets. We will cover the history of Maemo and explain what drove us to work on and create Maemo Leste. We will provide a technical overview of the software stack, show off and discuss the current status software stack, how we got there, our upcoming milestones and the challenges that lie ahead. Additionally, we'll take some time to discuss the "hacker" aspect of Maemo Leste. such as (only) supporting mainline Linux, future (first class) Tor and Wireguard integration, bleeding edge open GPU drivers and the availability of all the packages of Debian. Next to that, we will explain the development setups, build servers and infrastructure, provide some information on how to port Maemo Leste to a new device, dive into possible Android compatibility and hardware and driver issues difficulties (such as mobile GPU drivers and the current open source solutions).
