I concluded that the description was related to the use of the us+dvorak-alt-intl layout, and not to g-c-c setting incorrect options. Observations from use of the us+intl layout:
Alternate Characters Key to None -------------------------------- $ gsettings get org.gnome.desktop.input-sources xkb-options ['lv3:ralt_alt'] Right Alt according to xev: Alt_R Alternate Characters Key to None + Compose key to Right Ctrl ------------------------------------------------------------ $ gsettings get org.gnome.desktop.input-sources xkb-options ['lv3:ralt_alt', 'compose:rctrl'] Right Alt according to xev: Alt_R Right Ctrl according to xev: Multi_key Alternate Charters Key to None + Compose key to Right Alt --------------------------------------------------------- $ gsettings get org.gnome.desktop.input-sources xkb-options ['lv3:ralt_alt', 'compose:ralt'] Right Alt according to xev: Multi_key I see only expected options and expected results. So please elaborate on how you think that g-c-c behaves incorrectly, preferably with a reproducible use case. ** Changed in: gnome-control-center (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1969396 Title: Can't use Right Alt as compose key with English (Dvorak, alt. intl.) layout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1969396/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
