However: in the particular case of disabling the 'Compose Key' (which has a non-empty default), the setting is not persisted.To explain another way: although disabling the 'Compose Key' using the keyboard panel takes effect in the current session, it is restored to the default value ('Left Super' in this case) after the user logs out and logs back in.
I can't reproduce that behavior on my Debian testing.
This seems to be because when the 'Compose Key' is disabled, there is no configuration entry for it written to the user's relevant dconf entry, which is '/org/gnome/desktop/input-sources/xkb-options'.
For me there is. If I choose Left Super as the Compose key I can confirm it instantly this way:
$ gsettings get org.gnome.desktop.input-sources xkb-options ['compose:lwin'] And if I disable the Compose Key control: $ gsettings get org.gnome.desktop.input-sources xkb-options @as []
As a workaround it is possible to use the 'dconf' command-line interface to configure an empty mapping for the compose key: $ dconf write /org/gnome/desktop/input-sources/xkb-options "['compose:none']"
I don't think "compose:none" is a valid XKB option. And you really shouldn't need to do that.
It looks like this could be the same issue as reported in #1027003, except for a different key within the same settings panel.
Similar indeed, but not same issue I think. Before I added a patch as a fix of #1027003, there was no way to disable the Alternate Characters Key control. But a way to disable the Compose Key control was and is present via code which has been committed upstream.
