[ltp] Getting Fn-F2 to lock the screen

[Marcus Better]

The Fn-F2 (Lock) and Fn-F3 buttons on my R60 do not work. I'm running Debian
(amd64), kernel 2.6.20, ibm-acpi, acpi-support 0.90-4, hal 0.5.8.1-6.1 and
KDE with kpowersave.

/var/log/acpid.log shows the following (for Fn-F2):

[Thu Mar 15 11:59:38 2007] received event "ibm/hotkey HKEY 00000080
00001002"

~# cat /etc/acpi/lockbtn.sh
#!/bin/sh

. /usr/share/acpi-support/key-constants

acpi_fakekey $KEY_COFFEE


KEY_COFFEE is 152, but "acpi_fakekey 152" doesn't do anything. "xev" doesn't
show anything when I press Fn-F2 either.

So, how can I catch the KEY_COFFEE event?

Fn-F3 shows similar behaviour.

The following function keys do work:
Fn-F4 (Sleep)
Fn-F8 (Touchpad)
Fn-F12 (Hibernate)

Thanks,

Marcus
