It's videos like that which are the source of much frustration to me. The narrator says "First of all we have to start an xmir window, and I will do this from a remote login where I have already lined up the commands..." . The commands to get xmir to work are never shown. I've seen several videos like this that show xmir can work on at least some Ubuntu Touch devices, but I've found none that show how to actually get xmir to run. What little snippets of nonvideo documentation I've found has only allowed me to brick the phone a few times. I've seen even less evidence that SailfishOS actually can work as an X11 server.
