Umm...
With GDM3, Ubuntu.Xorg session correctly set GTK_IM_MODULE and other environments.
In this case, im-config will be launched from /etc/X11/Xsession.d/70im-config_launch.
If GTK_IM_MODULE and others is not be set on Wayland only,
I thought this will be caused by systemd service file.
However lightdm worked with Wayland, more need to be investigated further...
