I was inspired by the behavior kopete is showing on locking the session
manually (e.g. turning on the screensaver with a black screen) and
automatically setting the away status of my instant messenger. For
Jabber I'd like to use a different client (gajim) that is not as
integrated in kde as kopete is. The client provides a dbus interface and
I'm able to change the status issuing some commands.

How can I use the kde infrastructure to easily issue the appropriate
commands on locking and unlocking the screensaver? I preferably use the
facility kde provides for locking the session. Are there any events I
can hook upon? Any hints to the documentation for reading or ideas how
to implement it would help me.

I think KDE calls the kdesktop_lock helper tools when it wants to lock the
session, so you could rename this utility and create a script with the
original name that does your additional commands and the calls the renamed
tool.

Not sure about the unlocking, my guess is that kdesktop_lock blocks (does not
return) until the unlock, so the script might be able to handle the
additional unlocking operations afterwards as well.

Thanks for the tip. I tried it out yesterday and it works as expected.
Your guess is right that kdesktop_lock blocks. Therefore in my wrapper
script it is doing somethin before calling the real kdesktop_lock and it
is doing something after kdesktop_lock. It is important that the wrapper
script passes the options on to the the real kdesktop_lock program.

Greetings, Nico.
