Distributions offering Plasma Mobile
Neon based reference rootfs (recommended)
“Official” image, based on KDE Neon. Targeted at newer devices (with 1GB+ RAM). KDE Neon itself is based upon Ubuntu 18.04 (bionic). This image is based on the dev-unstable branch of KDE Neon, and always ships the latest versions of KDE frameworks, kwin and Plasma Mobile. It also uses Halium as hardware adaption layer.
Debian based reference rootfs
Prebuilt rootfs images for devices supported by Halium and by the mainline kernel. Currently, these images support i386, armhf and some arm64 devices (experimental).
Third-party distribution especially (but not only) targeted at older devices, based on Alpine Linux.
PostmarketOS (pmOS), is a touch-optimized, pre-configured Alpine Linux that can be installed on smartphones and other mobile devices. The project is at very early stages of development and is not usable for most users yet.
Neon based amd64 ISO image
This ISO image is using the same packages as the Neon based reference rootfs, just compiled for amd64. It can be tested on non-android intel tablets, PCs and virtual machines.
