Sample Fn-F7 script

Seva:

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:

<code>
# fn-F7
event=ibm/hotkey HKEY 00000080 00001007
action=/usr/local/sbin/thinkpad-fn-f7
</code>

Create /usr/local/sbin/thinkpad-fn-f7:
<code>
#!/bin/sh
#@ seva sevatech.com

# 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;

echo "internal" > $STATE_FILE
