If you can't use mainline Linux and/or have no GPU acceleration that's no use at all.

It's sort of theoretically useful whilst being practically pointless unless you want to produce your own OS.

How do I get into a Linux userland with X11 and a touch driver on my Galaxy Note 8? The answer is pretty much "write it all yourself, quickly before the hardware becomes obsolete".

I hope that the librem5 gains traction for that reason alone - producing a critical mass of developers.

You can chroot into a normal ARM distro and run the X11 server directly on Android. Works pretty well unless you need non-ES OpenGL.

This still requires running Android, most likely with an old kernel and nonfree blobs.
