>> can I set this up as an alternative WM and select it in my gnome-login-manager screen? Yes. >> Or do I have to install it as a completely separate DM? I'm not sure what you mean. The Ubuntu package provided lets you select this desktop from the login screen ( as opposed to i3, Plasma, or Gnome ). This is essentially a new Desktop Environment, made up of gnome and i3. >> Also, is this really only for Ubuntu? Unfortunately yes. I've tried looking at packaging this for Arch Linux, but it looks like quite a bit of dependencies are forked ( i3blocks is now i3xrocks ). Not everything is pushed upstream. Getting this to work on non-ubuntu based distributions looks tricky if you're not familiar with packaging already.
