What works

  • USB networking
  • Framebuffer graphics (Xorg/Wayland)

Requires running Android services/using libhybris

  • Wi-Fi (needs MediaTek's custom firmware loader)
  • 3D acceleration (via libhybris and xf86-video-hwcomposer)
  • Audio (via libhybris and pulseaudio-module-droid, possible to achieve with ALSA configs)

What does not work

  • Everything else not mentioned specifically

Installation

The easiest way for now is to use the Flash Tool from official flashing guide, replacing linux.img in the firmware package with planet-geminipda.img and linux_boot.img with boot.img-planet-geminipda.

The device package also includes an initramfs hook, which will try to mount the userdata and linux partitions, looking for a /postmarketOS.img file (exported as planet-geminipda.img). This can be used for non-intrusive installation. That Image file needs to be expanded to the wanted size in advance, for example:

% truncate -s 2G postmarketOS.img
