The owner was root:root, must have changed it by mistake when I put back password from previous install of Ubuntu. Doing chown root:shadow /etc/shadow and chmod u=r,g=r /etc/shadow fixed the problem.
Thanks for the tip. Have to be more careful next time I modify shadow and password files. So this is not a bug about screensaver not accepting valid password, but a bug raport of the screensaver not showing warning message about wrong permissions in the /etc/shadow file. -- Password does not unlock screen https://bugs.launchpad.net/bugs/600631 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
