Is seems that this shortcut is stored in the gsettings scheme "org.gnome.desktop.input-sources" in the key "xkb-options"
I found this workaround: $ setxkbmap -option compose:rwin The other values in the gsettings key are also ignored and can be applied with setxkbmap too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1242330 Title: Shortcut for compose key has no effect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1242330/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
