Talk:Sample Fn-F7 script
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
- This is to figure out which user and X11 display to work on
- 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
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2048 x 2048 VGA connected (normal left inverted right) 1600x1200 60.0 + 59.9 1280x1024 75.0 59.9 1152x864 74.8 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 LVDS connected 1024x768+0+0 (normal left inverted right) 304mm x 228mm 1024x768 60.0*+ 50.0 800x600 60.3 640x480 60.0 59.9
with VGA on
VGA connected 1600x1200+0+0 (normal left inverted right) 367mm x 275mm 1600x1200 60.0*+ 59.9 1280x1024 75.0 59.9 1152x864 74.8 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 LVDS connected 1024x768+0+0 (normal left inverted right) 304mm x 228mm 1024x768 60.0*+ 50.0 800x600 60.3 640x480 60.0 59.9
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 VGA connected 1600x1200+0+0 (normal left inverted right) 367mm x 275mm 1600x1200 60.0*+ 59.9 1280x1024 75.0 59.9 1152x864 74.8 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 LVDS connected (normal left inverted right) 1024x768 60.0 + 50.0 800x600 60.3 640x480 60.0 59.9
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 (
Regarding 1. acpid runs as root, so I switch to a user account before runinng xrandr, however I need to figure out which user to switch to -- hence the hack.
Regarding 2. that doesn't tell us if screens are being mirrored or exended, just active, i think that in combination with some other tools (xwininfo -root perhaps?) could work.
