Title:
Difficulty setting up multimonitor with fractional scaling
Status in mutter package in Ubuntu:
Confirmed
Bug description:
I've enabled fractional scaling and set my laptop's 3840x2160 screen
to 175% scaling. Upon plugging in an external 1920x1080 monitor, my
laptop's screen resets to 200% scaling, and the external screen is set
to 100%, to the right of my laptop's screen.
If I try to set the laptop screen back to 175%, the Displays panel
does not allow me to Apply, and journalctl outputs: Config not
applicable: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs:
Logical monitors not adjecent
Putting the external screen on the left or top of the laptop screen
allows Apply to work (bottom or right does not work), but immediately
reverts to the auto-set settings (200% laptop with 100% external on
the right) and then clicking "revert" on the "revert or keep" dialog
sets things to the requested scale factor and position (175% laptop
with 100% external on the top/left).
I've also seen the settings randomly reset to 200% laptop with 100%
external on the right upon doing things like clicking reply in
evolution to open up a new compose window.
That's a bit long winded, so here's a shorter rundown of bugs description:
1) Upon connecting an external screen, the laptop screen scaling changes
2) Can't set external screen to the bottom or right of laptop screen with
fractional scaling
3) Upon Application, the requested settings are reverted, and then reverting
the reversion applies them, while "keeping" the change reverts
4) Certain random actions appear to reset to the undesired settings
