Duplicate / change laptop screen to HDMI output
-
Hello forum!
I have got myself a very nice debian build of retropie and emulationstation running on an i7 Latitude E7470 laptop. My final step is to push the output to a TV rather than the laptop screen and at this point I'm struggling.
When I plug the hdmi in, the display gets extended and I'm trying to find a way of either duplicating the output or pushing it solely to the TV.
I have been trying to use xrandr as per this article https://unix.stackexchange.com/questions/371793/how-to-duplicate-desktop-in-linux-with-xrandr but get a return of "can't open display" when I run xrandr --current.
Can anyone steer me in the right direction?
Thanks!

Are you running
xrandrfrom a terminal in the desktop env or from a console/text terminal ? It needs to be run from a desktop session. -
@mitu - Thank you! I wasn't. I am now and the xrandr commands have worked.
