Description of problem: I unsuspended my system from overnight, but one of my external monitors didn't get used. I went to the system settings program to see if there was an issue. Just a second after I clicked on the monitors, I had this issue. It's fairly common where the one monitor doesn't get recognized when I unsuspend. The external monitor that's plugged directly into my laptop's vga port always works and it's always the monitor that's plugged into the dock's video port that's using a dvi adapter that will not get recognized. If I do a full init 0 at night and then power up in the morning, all monitors get detected 100% of the time.

I just tried to reopen the system settings application. It opened fine, but when I clicked on the Display and Monitor, it again failed. That prompted me to start writing this update. For doing that, I opened the system settings a third time to verify my steps. This time, rather than clicking on Display and Monitor, I clicked on Device Actions and it again failed. I again opened the system settings and this time I clicked on Startup and Shutdown, and that worked fine. I clicked on Color in the Appearance group at the top and that worked. Clicking on Systemd at the bottom worked, too. I clicked on a number of options and they all worked. I even clicked on Device Actions and a few others in that group. They all worked until I got to Multimedia which failed. It seems like Multimedia and the Display and Monitor will always cause it to fail, but the others will do that only sometimes. I changed the view style to by list and I was then able to go to hardware, Display and Monitor, then compositor. That worked fine. When I clicked on Display Configuration, it crashed again. For Multimedia, I can click on Audio and Video, but if I click on Audio Volume, it crashes.
This bug appears to have been reported against 'rawhide' during the Fedora 25 development cycle. Changing version to '25'.
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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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.
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
