Comment 31 for bug 1969637

It seems there is still an edge case issue.
ctrl+; wouldn't work (eg: in gedit) on my freshly rebooted host, with up to date softwares proprietary nvidia drivers, Xorg and gnome on a 22.04 release-upgraded from a 21.10 initial installation)

ctrl+; was working with `GTK_IM_MODULE=ibus gedit` (with an underlined 'e' where I could type an emoji name to select it, a different interface than what follows)

I then installed (for the first time) both xsettingsd and unity-settings-daemon-schemas and ctrl+; was working in gedit (showing black or at least theme colored background box with emoji pictures) but not in gnome-terminal (even with `GTK_IM_MODULE=ibus gnome-terminal`)
The following env var hadn't changed:
XMODIFIERS=@im=ibus
GTK_MODULES=gail:atk-bridge
QT_IM_MODULE=ibus
(GTK_IM_MODULE was still unset)

I then uninstalled xsettingsd and unity-settings-daemon-schemas (also tried with --purge) and ctrl+; still works with gedit and still doesn't with gnome-terminal, even with a fresh reboot.

note : I have a "French Alt." keyboard layout
