I'm running Xubuntu 14.04 with an Apple USB QWERTY keyboard. Up until last week, RAlt was working fine as my compose key and Ctr-Shift-U was working for Unicode entry. However, it has stopped working.
Here is the keyboard layout in /etc/default/keyboard:
XKBMODEL="apple"
XKBLAYOUT="us"
XKBVARIANT=""
XKBOPTIONS="lv3:lalt_switch,compose:ralt"
I have "Use system defaults" selected in Settings-->Keyboard-->Layout.
I tried re-running sudo dpkg-reconfigure keyboard-configuration but it didn't help.
Is there anything else I can try? I'm not having a lot of fun typing French and German without a compose key at the moment!
Thanks,
Tom
