As of now I’m migrating from Gnome to i3. Thus, when I hook up an external monitor to my laptop.
xrandr --output <monitor> --auto --above <primary monitor>
To list all connected monitors and find out what they’re called, you use “xrandr“. It will look something like this:
simon@tuxflux: xrandr Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767 eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 282mm x 165mm 1920x1080 60.00*+ 40.00 1400x1050 59.98 1280x1024 60.02 1280x960 60.00 1024x768 60.00 800x600 60.32 56.25 640x480 59.94 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 connected (normal left inverted right x axis y axis) 1920x1080 60.00 + 1680x1050 59.88 1600x900 59.98 1280x1024 75.02 60.02 1280x800 59.91 1152x864 75.00 1280x720 59.97 1024x768 75.08 60.00 832x624 74.55 800x600 75.00 60.32 640x480 75.00 60.00 720x400 70.08 DP1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis)
As you can see, my monitors’s called HDMI1 and eDP1. So to use my external monitor (HDMI1) right of my laptop, I fire:
xrandr --output HDMI1 --auto --right-of eDP1
Instead of “–right-of”, you could use:
--left-of <output> --right-of <output> --above <output> --below <output>
To rotate the display left-side:
xrandr --output HDMI1 --rotate left
Instead of “–right-of”, you could use:
--left-of <output> --right-of <output> --above <output> --below <output>
