Note: you will need to change the internal and external resolution until someone fixes this script to figure it out from xrandr, you may also need to change output names from "VGA" and "LVDS" to what your xrandr tells you.

why not just use --auto ?

xrandr --output VGA --auto

xrandr --output VGA --off

xrandr --output LVDS --auto

xrandr --output LVDS --off


Good point, made the changes --seva


  1. This is to figure out which user and X11 display to work on
  2. TODO there has to be a better way to do this?

SU="su $(w -h -s | grep ":[0-9]" | head -1 | awk '{print $1}') -c" export DISPLAY=$(w -h -s | grep ":[0-9]" | head -1 | awk '{print $3}'

As the xrandr command can be run by the user is this necessary? if the script called by Fn7 can be run by an ordinary user then is it not equivalent to running the commands in an xterm?

djc@Twingo:~$ xrandr --output LVDS --auto --output VGA --off
djc@Twingo:~$ xrandr --output LVDS --off --output VGA --auto
djc@Twingo:~$ xrandr --output LVDS --auto --output VGA --auto


concerning detecting what is currently active from xrandr. with VGA off xrandrq shows

with VGA on

with LVDS off:


djc@Twingo:~$ xrandr --output LVDS --off --output VGA --auto
djc@Twingo:~$ xrandr -q
Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 2048 x 2048

so detection should be possible on the differences between

VGA connected 1600x1200+0+0 (normal left inverted right) 367mm x 275mm
VGA connected (normal left inverted right)
LVDS connected (normal left inverted right)
LVDS connected 1024x768+0+0 (normal left inverted right) 304mm x 228mm

eg between "xxxx connected nnnnxnn+0+0 (" and "xxxx connected ("
