Some more info: This bug affected me on a clean install of Ubuntu 20.04.
On upgrading another machine from 18.04 to 20.04 I found that I had both xscreensaver and xfce4-screensaver installed. This caused me to have to do a double unlock each time I wanted to wake the PC. I therefore deleted xscreensaver and got the same problem as on the clean installation, only worse. On the clean installation I could type the unlock password even though unlock-widget was not visible; on the upgraded machine I could not unlock at all. I therefore removed xfce4-screensaver and re-installed xscreensaver. This fixed the problem. I now have two usable systems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892621 Title: No login screen when waking from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-power-manager/+bug/1892621/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
