Might as well leave this here, http://mohammadag.xceleo.org/Qt-examples/slide2lock/

If anyone's interested in it, I can package it up quickly and upload it to devel.

another approach:

apt-get install dbus-scripts

or install dbus-scripts via App Manager

add these 2(!) lines to /etc/dbus-scripts.d/dbus-scripts-settings (create the file if it doesn't exist)

Code:

#:soundonslide
/etc/dbus-scripts-scripts/playswoosh * * org.freedesktop.Hal.Device Condition ButtonPressed cover

create a folder /etc/dbus-scripts-scripts, and a file therein named playswoosh (my StarTrek style sound on slide out kbd, I'll just augment the code a bit here for the requested purpose). Set the file `chmod +x`

place following code to /etc/dbus-scripts-scripts/playswoosh:

Code:

#!/bin/sh
stored=/home/user/.slidestore;
slide=$(cat sys/devices/platform/gpio-switch/slide/state);
if [ X$slide == X$(cat $stored) ]; then exit 0; fi;
if [ X$slide == Xopen ]; then 
  /usr/bin/play-sound /usr/share/sounds/ui-charging_started.wav;
##next two lines are new and untested :-) and relevant for locking the screen
else
  /usr/bin/dbus-send --system --type=method_call \
    --dest=com.nokia.mce /com/nokia/mce/request \
    com.nokia.mce.request.req_tklock_mode_change string:"locked"
fi;
echo -n $slide >$stored

if you don't like the slide-out-swoosh, do this instead:

Code:

#!/bin/sh
stored=/home/user/.slidestore;
slide=$(cat sys/devices/platform/gpio-switch/slide/state);
if [ X$slide == X$(cat $stored) ]; then exit 0; fi;
if [ X$slide != Xopen ]; then 
  /usr/bin/dbus-send --system --type=method_call \
    --dest=com.nokia.mce /com/nokia/mce/request \
   com.nokia.mce.request.req_tklock_mode_change string:"locked"
fi;
echo -n $slide >$stored

Sorry for not actually testing it, if it has a typo, please let me know :-)
[edit] If somebody has this original chirping sound of Kirk's communicator, please toss it over. For the protocol: I know $stored better be a file in /tmp, feel free to edit.
[edit2] If you want to do other nice things with dbus-scripts, use dbus-monitor to find out about the dbus signal match-pattern to add to /etc/dbus-scripts.d/* (where * is any file, either the existing dbus-scripts-settings, or an arbitrary file you create for your new action)

cheers

new version not playing any sound when lock-switch is held while sliding kbd open:

Code:

#!/bin/sh
# file: /etc/dbus-scripts-scripts/playswoosh
# chmod +x
stored=/tmp/slidestore;
slide=$(cat sys/devices/platform/gpio-switch/slide/state);
if [ X$slide == X$(cat $stored) ]; then exit 0; fi;
if [ $slide == open -a $(cat /sys/devices/platform/gpio-switch/kb_lock/state) == open ]; then /usr/bin/play-sound /usr/share/sounds/ui-charging_started.wav; fi;
echo -n $slide >$stored

for the screen locking on closing kbd slider you may want to add the "else" lines from above

I'm planning to change lock-switch hold to not immediately unlock screen, but instead slowly ramp up screen brightness from zero until you release the switch. Also on long "press" of lock-switch activate profile: silent.

Usecase: e.g. in cinema you want to "unlock" smoothly to a somewhat more discreet operation mode - so you press&hold the lockswitch, slide open kbd (no sound thanks to above little tweak), and watch the screen come up slowly in brightness until you just see enough and release the lock-switch.
Well, this is maybe just a bit OT in this thread, but anyway.
