It's a bit late XD, but try after Saramburu's commands: sudo chmod g+r /etc/shadow
It worked for me ;) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/353356 Title: Gnome screensaver lock always reports "incorrect password" Status in “gnome-screensaver” package in Ubuntu: Invalid Bug description: Binary package hint: gnome-screensaver When inactive, the screensaver locks the workstation. When logging back in, I enter my password. This always returns "incorrect password". Workaround: hit "Switch User" log in as that same user with the denied password, revealing the session that was logged out of. I changed the password: "sudo passwd". No change in behavior. The question: where is it drawing the password from if not from the same place that the regular login derives it? And how can I fix this admittedly small but annoying problem?
