Public bug reported: System: Ubuntu Cosmic
Package: gnome-control-center: Installed: 1:3.30.1-1ubuntu2 Candidate: 1:3.30.1-1ubuntu2 Version table: *** 1:3.30.1-1ubuntu2 500 500 http://ca.archive.ubuntu.com/ubuntu cosmic/main amd64 Packages 100 /var/lib/dpkg/status Expected: an error message about non-adjacent displays when non-adjacent displays were preventing a resolution change What happened: a generic error message about "hardware limitations". When trying to change the resolution of my displays, when multiple displays were connected, it failed with the error "Changes Cannot Be Applied: this could be due to hardware limitations." However, if I run gnome-control-center from the command line, I get the following, much more helpful output: (gnome-control-center:7405): display-cc-panel-WARNING **: 10:15:42.267: Config not applicable: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Logical monitors not adjecent Indeed, moving the displays to be adjacent within the settings app fixed the problem and allowed the resolution to be changed. The GUI should inform users when non-adjacent displays are preventing a settings change, instead of failing with an uninformative message.
