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 Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1573755 Title: compose and dead keys stopped working in gnome terminal Status in firefox package in Ubuntu: Confirmed Status in gnome-terminal package in Ubuntu: Confirmed Status in nautilus package in Ubuntu: Confirmed Status in thunderbird package in Ubuntu: Confirmed Bug description: After upgrading to 16.04, entering characters using dead keys and using the Compose key stopped working in Gnome Terminal, acting like they are normal (non-dead) keys. Other applications, even those who use the same libvte (e.g. ROXTerm), don't have this issue. This happens with both the "Belgian" and "English international with AltGr dead keys" layouts.
