ThinkPad undock key Fn+F9 has no effect

[Jeffrey Baker]

Binary package hint: acpi-support

In Karmic, the key combination to undock a ThinkPad X61 (Fn+F9) has no effect. This worked in Jaunty and previous releases. The key seems to work, according to acpi_listen:

# acpi_listen
ibm/hotkey HKEY 00000080 00001009

That event is not mapped to anything in /etc/acpi. The dedicated key on the dock itself does work as expected.

I believe the fix is as simple as these three lines:

# cat events/lenovo-undock
event=ibm/hotkey HKEY 00000080 00001009
action=/etc/acpi/undock.sh

# cat undock.sh
#!/bin/sh

echo 1 > /sys/devices/platform/dock.0/undock

I'm not sure why there are dock.1 and dock.2 platform devices. Anyway, this fix works for me.

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 the same event as the prepare-to-undock button. This, instead of adding a new script to duplicate the functionality.
