Title:
Ubuntu 20.10 gnome-control-center dropdowns missing for screen
resolution and primary screen
Status in gnome-control-center package in Ubuntu:
Confirmed
Status in gnome-control-center source package in Groovy:
Confirmed
Bug description:
The Ubuntu 20.10 version of g-c-c lacks the dropdown controls for
changing screen resolution or selecting the primary monitor. Where
there is normally a dropdown, there is just a label showing the
current screen resolution or primary monitor. In some cases the
dropdown is there, eg it might be there for the laptop monitor but not
the external monitor(s). Changing the resolution of a monitor using
xrandr sometimes makes the dropdown appear in g-c-c.
I have attached a screenshot showing the issue.
