Thecode in linux/drivers/acpi/dock.c seems to invoke ACPI routines
"_DCK" and "_EJ0". I'm afraid I don't know much about the ACPI

My X61 is docked in an UltraBase X6 whose Ultrabay Slim contains a DVD

More info. The "prepare to undock" key generates the following
according to "lshal -m":
platform_dock_0 property info.docked = false
computer_logicaldev_input_0 condition ButtonPressed = switch-videomode

computer_logicaldev_input_3 condition ButtonP

If the prepare-to-undock button (on the UltraBase itself) works and you
want Fn-F9 to replicate its function then I'd expect that it is better
for a Fn-F9 keypress to be mapped in such a way that it generates th
