[Bug 1844509] Re: ubiquity-dm fails to start

[Launchpad Bug Tracker]

This bug was fixed in the package ubiquity - 19.10.11

---------------
ubiquity (19.10.11) eoan; urgency=medium

  * ubiquity-dm: Adjust to GNOME Shell's gsd-xsettings related changes. GNOME
    Shell now launches gsd-xsettings itself, via the systemd units provided in
    `gnome-session` and `gnome-settings-daemon-common`. This conflicts with
    what we're doing in ubiquity-dm in two ways:
      - We are trying to launch gsd-xsettings ourselves, and you can only have
        one of these running at a time.
      - The user systemd environment does not have $DISPLAY in it, meaning
        that gsd-xsettings can't connect to the X server.
    Stop launching gsd-xsettings from ubiquity-dm, letting the shell handle it
    directly, and also export $DISPLAY into the D-Bus and systemd environments
    so that it can start up. (LP: #1844509)
  * ubiquity-dm: Don't launch ibus when we're running gnome-shell. These days
    gnome-shell takes care of running it itself.
