To add to that, another quick fix did work for me, the one suggested here: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/163525 i.e.:
sudo chown root:shadow /sbin/unix_chkpwd sudo chmod 2755 /sbin/unix_chkpwd The suggestion there was that this might be a bug in libpam-modules, rather than gnome-screensaver (if it is the same bug of course). -- password not recognized after suspend https://bugs.launchpad.net/bugs/227994 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
