Non-existing "Unknown Display" detected
Affected version
- OS: Fedora Workstation 36
- Mutter: 42.0 (Release 6.fc36)
Bug summary
An extra non-existing display is detected named "Unknown Display" and shown under Displays section in Settings! Also upon first boot after upgrading to Fedora 36 bringing GNOME 42.1, my GDM login screen had a very wide resolution spanning beyond my display size and space. Almost all windows are opened in maximized state which wasn't the case on GNOME 41.6! I believe this also has something to do with incorrect display count and layout detected by the system.
I had to disable this "Unknown Display" in the Settings to get my desktop to display in the correct resolution.
I'd say this a regression since I had no such issues on GNOME 41.6 and Fedora 35.
Relevant logs, screenshots, screencasts etc.
