Fist of all, I don't know details about history of upstart/unity and user session system. There is no conclusion, just my research.
--- For Unity8/Mir, upstart script of im-config was added LP #1433831 This Ubuntu only script should be removed from im-config package. Since switching user session from upstart to systemd, above upstart script is convert to systemd unit on 0.29-1ubuntu14. However this unit file uses initctl command, then this unit work on both of systemd and upstart installed system only. Legacy (Xorg) system will launches /etc/X11/Xsession.d/70im-config_launch and set STARTUP variable to exec /usr/bin/im-launch. All environment variables are set, no problem. Wayland system doesn't exec /etc/X11/Xsession.d, i.e. any mechanism to set environment variables is needed as like on Unity8/Mir. (old) systemd unit doesn't work by two reasons. 1. use initctl command of upstart 2. bind to graphical-session.target which is not launched on ubuntu If I understand correctly, graphical-session.target and graphical-session-pre.target will be launched for unity8 system and others. At artful, this target are not depended by any target and service. /usr/lib/gnome-session/run-systemd-session will stop these targets, but this script will be executed from unity.desktop only. How about use basic.target instead of graphical-session.target? I attach sample im-config.service. sudo cp im-config.service /usr/lib/systemd/user/ systemctl --user daemon-reload systemctl --user enable im-config.service (and restart session by logout and login) This service file will work about environment variables. $ env | grep -E '_IM|XMOD' CLUTTER_IM_MODULE=xim QT4_IM_MODULE=xim QT_IM_MODULE=ibus XMODIFIERS=@im=ibus GTK_IM_MODULE=ibus However suggestion window will be displayed on top left of display, not near cursor on gedit and gnome-termial. The reason isn't known. ** Attachment added: "im-config.service" https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1720250/+attachment/4959803/+files/im-config.service -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720250 Title: im-config configuration ignored with gdm3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1720250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
