Description of problem: On wayland session on the setup with two monitors (laptop and external) the mirroring doesn't work. When I go to the settings and switch to mirroring the external monitor doesn't wake up. This affects for example presentations when you want to show your screen. This affects just wayland sessions. Version-Release number of selected component (if applicable): mutter-3.22.1-2.fc25.x86_64 How reproducible: always Steps to Reproduce: 1. Go to Settings->Displays choose one monitor 2. Click on mirroring 3. Actual results: external monitor doesn't wake up Expected results: mirroring on two monitors Additional info: I propose this as a blocker. Possible criterion would be "All applications that can be launched using the standard graphical mechanism of a release-blocking desktop after a default installation of that desktop must start successfully and withstand a basic functionality test." As I think that mirroring is basic funtionality of Display setting Rui Matos probably work on this (at least Jiri Eischmann says so).
Should be fixed in mutter-3.22.1-5.fc25.x86_64, please re-open if it's not.
I tried it and it seems to work.
