Lock screen does not work on Ubuntu 20.04

  • 772

Lock screen does not work on Ubuntu after upgrade to 20.04. I have it turned on in tweaks and it does not work. When I click "lock" the screen simply reloads and disables some extensions in the process. It does not work at all. How can I fix this?

ls -al ~/.local/share/gnome-shell/extensions:

    Holy !@#$% batman! You've got WAY too many GNOME Shell extensions, and many of them overlap in functionality.

    First step...

    Go to https://extensions.gnome.org/local/ and disable ALL extensions, then restart GNOME Shell with ALT+F2, then r, then ENTER. Then retest the lock screen, and see if it works normally.

    Second step...

    Let's start by cleaning out your /usr/share/gnome-shell/extensions...

    sudo rm -r /usr/share/gnome-shell/extensions/*gcampax.github.com

    Restart the GNOME Shell using the previous instructions.

    This should leave you with these extensions in /usr/share/gnome-shell/extensions...

    Using the same web location that I gave earlier, REMOVE any remaining extensions that you either 1) don't really need, or 2) overlap in functionality. Then re-enable the remaining extensions one-at-a-time to see if one of them causes your lock screen problem. Restart the GNOME Shell after each disable/enable/remove(s) change.
