Very nice work,
but it doesn't work for me :/
I followed all steps but it won't change my lockscreen.. I changed the font and the background directory correctly.
The folder /etc/dbus.d didn't exist, so i created it via terminal "mkdir dbus.d" and created there the lockscreen file.
Slide to unlock was already removed before, imagemick is also installed.
I really don't know how to fix it.. already rebooted my phone and copied everything again into the folders..

/Edit: it seems like my dbus-scripts-session does not work..
