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:
- fn-F7
event=ibm/hotkey HKEY 00000080 00001007
action=/usr/local/sbin/thinkpad-fn-f7
Create /usr/local/sbin/thinkpad-fn-f7:
- !/bin/sh
- @ 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
