*** This bug is a duplicate of bug 26175 *** I cured mine by reselecting keyboard both in gnome and sudo dpkg-reconfigure xserver-xorg and renaming iceauthority to backup so a new one is created.
It would appear the bug is caused by keyboard config either in gnome or xorg -- Lock screen doesn't accept password https://launchpad.net/bugs/26184 -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
