> Disabling the key "/org/gnome/desktop/lockdown/disable-lock-screen" in dconf-editor solved the problem.
I'm not sure what you mean by disabling. If you mean set it to false, false is already the default value. It was at its default for me. I tried overriding it and setting it to false, but that didn't help. So this solution doesn't work for me. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1715435 Title: Can't lock screen with keyboard shortcuts when using lightdm Status in gnome-shell package in Ubuntu: Confirmed Status in lightdm package in Ubuntu: Confirmed Bug description: Trying to use Super+L or Ctrl+Alt+L, I cannot lock the screen.
