Description of problem: I installed Fedora 25 Alpha on 8/31/2016. I believe I could setup primary and secondary monitors on Fedora 25 Alpha then. I have done several updates since 8/31/2016. I net re-installed Fedora 25 Alpha today. I cannot join a secondary monitor in Wayland Fedora 25 Alpha. When I select the secondary monitor the Apply button does not become sensitive. Version-Release number of selected component (if applicable): control-center-3.20.1-1.fc25.x86_64 How reproducible: Always. Steps to Reproduce: 1.Start Gnome Control Center in Wayland session. 2.Select a monitor. 3.Set to be secondary. Actual results: Apply button does not become sensitive. Expected results: Apply button does become sensitive. Additional info: I can setup primary and secondary monitors in Fedora 24 in Wayland. In X11 session I can setup a secondary monitor in Fedora 25 Alpha.

A recent update has corrected the reported problem; however, when the monitors are joined and you select the secondary monitor and set the monitors to mirror, the primary monitor loses signal and you must log out and re-login for both monitors to be operational in the mirrored state.
I installed Fedora-Workstation-Live-x86_64-25-Wayland_Test_Day.iso to a hard drive for testing. I then did a dnf update.Joining displays now works properly as I noted in my previous comment but setting displays to mirror has changed from testing with my previous F25 setup. Now when changing to mirrored displays the primary display connected via DVI looses signal. If I logout and login or shutdown and login the DVI device does not mirror. It appears the gdm background continues to be displayed on the DVI device after login. The mouse cursor is displayed on both as in mirrored displays but the background hides what should be seen on the DVI device. X11 has no problem. lsmod: radeon 1507328 8 i2c_algo_bit 16384 1 radeon drm_kms_helper 151552 1 radeon ttm 94208 1 radeon lspci: 00:01.0 PCI bridge [0604]: ASUSTeK Computer Inc.

Updated F25 Beta today. This bug is fixed by todays's update. Both mirror and join problems have been cleared.
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
