This is not supported by logind. You cannot allocate sessions from other sessions, only from the system daemon. This is because we try to keep the various session definitions in sync, for example the audit session which is nowadays "sealed" off by the kernel. Either use a display manager or simply "update" your existing session's tty to graphical temporarily, rather then placing things on a new tty. (Note that the Fedora startx script does this implicitly this way) Note that "systemd --user" is WIP (which is why you find very little documentation about it from us, except the most basic reference in the man pages). It was never supposed to be run from login sessions (it's not called "systemd --session" but "systemd --user" for a reason) except for debugging purposes. Recent systemd versions make this a bit harder than before since for security reasons normal user sessions do not get write access to their cgroup tree anymore, only [email protected] gets. Now, [email protected] is not complete yet. To be fully useful we need some support from X11, so that it can connect to the X11 display via $XDG_RUNTIME_DIR/display, rather than relying on $DISPLAY. Also, D-Bus needs to look for the bus socket in $XDG_RUNTIME_DIR too. We are working on this bit by bit. If you want this to go faster, then please work with us, and write patches for libX11 and D-Bus. If you need an quick solution immediately I suggest you simply chown the sessions cgroup tree to your own user. That's a hack, and requires privileges, but is what I do for testing purposes.
