This setup will let you use fn-F7 key combination to toggle between internal, mirror, external, or both screens. Tested on ThinkPad X60s running Fedora 8.
Add a "Virtual" statement to your /etc/X11/xorg.conf, the total resolution should be large enough to fit all your screens in the configuration you want, for example I have 1600x1200 monitor to the left of my internal 1024x768 monitor for a total max resolution of 2624x1200:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Virtual 2624 1200
EndSubSection
EndSection
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:
Note: you will have change EXTERNAL_OUTPUT and INTERNAL_OUTPUT to what xrandr shows, for example VGA and LVDS in this case:
xrandr | grep connected VGA connected 1600x1200+0+0 (normal left inverted right x axis y axis) 432mm x 324mm LVDS connected (normal left inverted right x axis y axis)
#!/bin/sh
#@ seva sevatech.com
EXTERNAL_OUTPUT=VGA
INTERNAL_OUTPUT=LVDS
EXTERNAL_LOCATION="--left-of $INTERNAL_OUTPUT"
# This is to figure out which X11 display to work on
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}')
# Save the state to the file until we can figure it out by running xrandr
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 --auto"
echo "external" > $STATE_FILE
}
function screen_internal(){
$SU "xrandr --output $EXTERNAL_OUTPUT --off"
$SU "xrandr --output $INTERNAL_OUTPUT --auto"
echo "internal" > $STATE_FILE
}
function screen_mirror(){
$SU "xrandr --output $INTERNAL_OUTPUT --auto"
$SU "xrandr --output $EXTERNAL_OUTPUT --auto --same-as $INTERNAL_OUTPUT"
echo "mirror" > $STATE_FILE
}
function screen_both(){
$SU "xrandr --output $INTERNAL_OUTPUT --auto"
$SU "xrandr --output $EXTERNAL_OUTPUT --auto $EXTERNAL_LOCATION"
echo "both" > $STATE_FILE
