Public bug reported:
I'm working with a friend to try to resolve an issue where her external
monitor does not work after the upgrade. It was functional before.
She just upgraded from Ubuntu 22.04 to 24.04, and is having issues
trying to connect an external monitor to her laptop (running Intel
graphics and x11). The control panel is displaying "Changes cannot be
applied", and the monitor itself is non-functional, but it does at least
appear in the control panel.
I had her try running gnome-control-center and it did give the error of
"GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Logical monitor
scales must be identical" while doing so.
We tried deleting the .config/monitors.xml file, and tried setting the
scaling factor to be the same, with no luck.
The version of gnome-control-center is 46.2-1ubuntu0.24.04.2
