But when i try to do :

bussiere@kusanagi [22:03:53] [~/script] [master *]
-> % xrandr --output Screen\ 0 --primary
warning: output Screen 0 not found; ignoring
bussiere@kusanagi [22:04:49] [~/script] [master *]
-> % xrandr --output Screen 0 --primary
xrandr: unrecognized option '0'
Try 'xrandr --help' for more information.

it doesn't work. How to type correctly Screen 0 for the --primary command of xrandr please ?

Thanks

xrandr

  Do you want to set either which screen by position, no matter the name, or by name? – Jacob Vlijm Nov 29 '17 at 21:41

"Screen 0" here describes your whole virtual display made of these two outputs:

• eDP-1-1: physical screen plugged to a display-port output
• HDMI-1-1: physical screen plugged to a HDMI output

(notice Screen 0 is 3286 pixel wide, which is 1366 + 1920, the two other outputs horizontal pixels)

I guess you want to use HDMI-1-1 as primary output, and the following command will fix that:

xrandr --output HDMI-1-1 --primary
