I've accidentally blocked the button, I don't know how.
And I tried to launch this command :
xrandr --output HDMI1 --pos 0x0 --mode 1920x1080 --rate 60
But it's not working.
Does someone know the command to enable the button "Show the same image on all screens", I don't see on the bottom-left corner of the window ?
Thanks a lot !
