My daughter's kubuntu has stopped accepting her password for login. I followed the advice here @ psychocats website and also tried to follow the advice on this page but there is no line that begins with "kernel".
In recovery I "dropped to root" and entered "passwd -d" then "passwd kiersten" and went through the password change, and it said successful, but then on reboot the password doesn't work, it just flashes then returns to the login screen Advice? She's running Kubuntu 12.04 dual with windows xp. Windows boots fine. Thanks in advance?
