I made this about... 2 years ago. I never shared it with anyone. As I recall, it runs Gnome with X11 or with Wayland utilizing android graphic drivers. If you run Wayland and want to use X11 it then uses XWayland. XWayland works, except for it only works with the first mouse click. I basically took as much sailfish stuff as I could and made it run on ArchLinux, this was with pulseaudio, and bluetooth I think, except I never did get hardware accelerated codecs to work (GST Droid). I also played with Hawaii.. http://hawaiios.org/download/distros/
Which is included, although it never ran that well. And weston is also an option to use with this, you can see this with the LightDM login screen. Remember this is 2 years old. If you upgrade pulse audio or anything else it might break everything because of the kernel and systemd and god knows what else.
Also, I don't currently have a touchpad to play with. If I recall this zip file has a kernel and a rootfs.tar.gz inside, and.. I am not sure what partition you stick it in, probably /dev/store/ubuntu... So.... Maybe when I get a touchpad, I can figure it out, or play with this again.
