Well... I wanted to try disabling my extensions to see whether I could get the Wayland session to work, when I noticed that Dash to dock was enabled - it was still left there after my upgrade from 16.04. After disabling it, Ubuntu Dock (if that was even what was running) appears to work fine.
So I'm guessing it might be a bug in Dash to dock, so I'm closing this - unless the bug originated in the interaction between the two, and some action still needs to be undertaken? ** Changed in: gnome-shell-extension-ubuntu-dock (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1784332 Title: Super+<num> shortcuts stop working after locking the screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1784332/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
