Ok, some hacking on the plane on the way to GUADEC got me really far on this; then we had a quick face to face to work through some conceptual issues. In the new user@ model, it's very important to note there is only one "stub" process per session (at least graphical ones - whether we change getty is a whole other topic). So for graphical, everything is launched from [email protected]. The side effect of this is twofold: 1) Pretty much all the user processes are no longer inside a session at all. 2) It is now much harder to log in multiple times graphically; this is kind of a crazy thing to do, but it's still *possible*. To do so, you wire up your userspace code to set the pile of usual environment variables to override (DISPLAY, DBUS_SESSION_BUS_ADDRESS, etc.) I can say though at least for GNOME we haven't supported this for years, so it's really not a change. For for adapting to 1), we agreed on adding the concept of a "primary" session, which is basically the first non-tty login. I've added a small API to systemd to look this up, and the patched GNOME to use it (although we partially still respect XDG_SESSION_ID). My current patches are here: https://people.gnome.org/~walters/user-session-patches I've been hacking on it using gnome-ostree; if there's interest I can toss up a VM. Before I spend too much time polishing the patches, I'd like to be sure the high level architecture makes sense. So please take a look at the patches at that level; I'll split them up cleanly with better commit messages after.
