I believe it is an ibus-daemon bug. I had the problem at least in gnome- terminal, firefox (but not under Unity), thunderbird. I solved it less brutally than flushing the whole user DConf database by resetting one key:
dconf reset /org gnome/desktop/interface/gtk-im-module which contained the value 'gtk-im-context-simple'. It worked: * for gnome-terminal after logging again, restarting the program wasn't enough. * for Firefox and Thunderbird only after restarting the system. The only user program that didn't restart after a relog was 'ibus-daemon', hence I believe it is his bug. What makes me wonder is why the Compose key worked on Firefox only under Unity and not GNOME 3. There might be a second bug there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573755 Title: compose and dead keys stopped working in gnome terminal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1573755/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
