Pyxtrlock is a program to lock a workstation while still displaying the screen. That is, keyboard and mouse can not be used until a password is typed on the keyboard, but the contents of the display isn't hidden. Fedora 25 switched to using Wayland by default, and pyxtrlock doesn't effectively the lock any more.
Is there a way to do this kind of lock under Wayland?
(I'm aware I could revert to using Gnome under X again. But I would like to continue to use Wayland, so I'm looking for a solution in the new environment.)
