Comment 0 for bug 1612951

I just upgraded Xubuntu 14.04 to 16.04, and I noticed my compose key wasn't working in any application in X. I verified my compose key was still set up in /etc/default/keyboard:

XKBOPTIONS="compose:ralt"

I googled around and ran these two commands:

sudo dpkg-reconfigure keyboard-configuration
sudo update-initramfs -u

But the problem persists. I notice that the compose key works fine in the console, but it doesn't work in any X application, including the terminal.

It looks like I'm not the only one experiencing this, and it doesn't seem limited to Xfce:
