It would be nice to be able to programmatically modify the display scaling factor, e.g. via a D-Bus message or running a script. Possible applications include: - creating several SDDM configurations, in order to start a Plasma session with a scaling factor that depends on the connected monitor - modifying scaling factor "on the fly", by running a script, when you switch to a different monitor, etc. Thank you!
You can do this with `kscreen-doctor`.
