Same problem, i just edited language selector and it disappeared, after restart i began to look at the settings and noticed that keyboard layouts in system settings -> regional and language are empty and it isn't possible to enable, setxkbmap still works for changing languages
-- After upgrade in kubuntu there are no keyboard layouts https://launchpad.net/bugs/67612 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
