In my laptop I am using an app called 'Displays" to manage the secondary monitor. I wanted to show the program to a colleague but he doesn't have it. There's no binary called displays on my computer, and no 'About' page to get the name of the program. How is it called? In wich package can I find it?
I attach an screenshot to see if someone can help

That "app" is a module in System Settings under Display and Monitor. It comes in a package called kscreen which is generally included along with the Plasma Desktop packages. It doesn't have a stand-alone executable, but you can invoke it from the command line using: kcmshell5 kcm_kscreen. (I believe there should be comparable settings modules available in other desktops).

if it is about Kubuntu

Code: Select all

sudo apt-get install kscreen
