This setup will let you use fn-F7 key combination to toggle between internal, external, or both screens. Tested on ThinkPad X60s running Fedora 8.

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.

Create /etc/acpi/events/thinkpad.conf:

  1. fn-F7

event=ibm/hotkey HKEY 00000080 00001007 action=/usr/local/sbin/thinkpad-fn-f7

Create /usr/local/sbin/thinkpad-fn-f7:

  1. !/bin/sh
  2. @ seva sevatech.com

EXTERNAL_OUTPUT=VGA EXTERNAL_MODE=1600x1200

INTERNAL_OUTPUT=LVDS INTERNAL_MODE=1024x768

DO=$(basename $0)

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}')

STATE_FILE=/var/lib/thinkpad/screen.state; if [ ! -e $STATE_FILE ]; then

       echo "internal" > $STATE_FILE

fi

STATE=$(cat $STATE_FILE)

function screen_external(){

       $SU "xrandr --output $INTERNAL_OUTPUT --off"
       $SU "xrandr --output $EXTERNAL_OUTPUT --mode $EXTERNAL_MODE --left-of LVDS"
       echo "external" > $STATE_FILE

}

function screen_internal(){

       $SU "xrandr --output $EXTERNAL_OUTPUT --off"
       $SU "xrandr --output $INTERNAL_OUTPUT --mode $INTERNAL_MODE --right-of VGA"
       echo "internal" > $STATE_FILE

}

function screen_both(){

       $SU "xrandr --output $EXTERNAL_OUTPUT --mode $EXTERNAL_MODE --left-of LVDS"
       $SU "xrandr --output $INTERNAL_OUTPUT --mode $INTERNAL_MODE --right-of VGA"
       echo "both" > $STATE_FILE

}

case "$DO" in

       thinkpad-fn-f7)
               case "$STATE" in
                       internal)
                               screen_external
                               ;;
                       external)
                               screen_both

                       both)
                               screen_internal
                               ;;
                       *)
                               screen_internal
                               ;;
               esac

               echo "usage: rename to thinkpad-internal, thinkpad-external, or thinkpad-both" >&2
               ;;
