This guide will help you configure Fn-F7 key combination to toggle between internal, mirror, external, or both screens. This was tested on ThinkPad X60s running Fedora 8, please comment if it works or does not work for you.

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 if you have 1600x1200 monitor to the left of your internal 1024x768 monitor, your total max resolution is 2624x1200 (See Xorg RandR 1.2 for more details):

Section "Screen"
       Identifier "Screen0"
       Device     "Videocard0"
       DefaultDepth     24
       SubSection "Display"
               Viewport   0 0
               Depth     24
               Virtual   2624 1200
       EndSubSection
EndSection

Restart X server at this point (i.e. logout and login).

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

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/bash

# External output may be "VGA" or "VGA-0" or "DVI-0"
EXTERNAL_OUTPUT="VGA"
INTERNAL_OUTPUT="LVDS"
EXTERNAL_LOCATION="left"

# Figure out which user and X11 display to work on
# TODO there has to be a better way to do this?
X_USER=$(w -h -s | grep ":[0-9]" | head -1 | awk '{print $1}')
export DISPLAY=$(w -h -s | grep ":[0-9]" | head -1 | awk '{print $3}')

# Switch to X user if necessary
if [ "$X_USER" != "$USER" ]; then
       SU="su $X_USER -c"
fi

case "$EXTERNAL_LOCATION" in
       left|LEFT)
               EXTERNAL_LOCATION="--left-of $INTERNAL_OUTPUT"
               ;;
       right|RIGHT)
