I had a brief look at this using the latest daily build ISO for Ubuntu MATE 21.04.
lightdm has code for disabling the MATE screensaver. I confirmed that it works by opening a terminal window within a guest session: $ gsettings get org.mate.screensaver lock-enabled false But I could still reproduce the issue, i.e. I switched to my regular user and then when trying to switch back to the guest session it prompted me for the non-existing password. We should keep in mind that the guest session feature is deprecated and disabled by default: https://askubuntu.com/q/915415 AFAIK nobody makes any effort any longer to make sure it keeps working when software is upgraded. ** Changed in: lightdm (Ubuntu) Importance: Undecided => Low ** Changed in: lightdm (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775088 Title: Ubuntu Mate guest session locked out when switching from another account To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-mate/+bug/1775088/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
