How to open the display settings in command line?

Question

I have Ubuntu 18.04 installed and when I have set up an additional monitor for my laptop which, for obvious reasons, is used as a primary monitor.

However, sometimes when I start the laptop the additional monitor stays blank and I have to either restart or restart gdm3 in order to have it working.

I have found that if I make a slight change in the Displays settings the second monitor wakes up. The problem is that it's quite hard to open that application when the main (additional) monitor is blank.

Is there a way to open Settings or Display settings from command line?

Just to make sure I've expressed myself clear enough this is the application I want to open:

PS: I've added nvidia tag because the GPU is Nvidia.

Solution

The command would be:

gnome-control-center display 

You can use tab completion with gnome-control-center to see a list of available panels:

$ gnome-control-center 
background        keyboard          printers          ubuntu
bluetooth         mouse             privacy           universal-access
color             network           region            user-accounts
datetime          notifications     removable-media   --verbose
default-apps      online-accounts   search            --version
display           --overview        sharing           wacom
info-overview     power             sound             wifi

I tried to find the same thing, my conclusion was that gnome settings is a module of gnome-shell & can't be run directly (from terminal) so I hope you get a better answer (outside of dconf-editor)
