I've worked with +Thomas Molloy
on a settings UI for light-locker in #Xubuntu
14.04. Not sure it also works in other desktops, I guess that's for you folks to test/find out :)
Anyhow, after writing it all in a rush, we've released version 1.0 in time for Ubuntu's Feature Freeze (currently hoping someone will sponsor it after +Sean Davis
has prepared the package).
If you want to try it, you can either
1) add the PPA (Trusty-only at the moment!): https://launchpad.net/~light-locker-settings-team/+archive/stable
2) grab the code from here (https://launchpad.net/light-locker-settings
), navigate to the light-locker-settings directory and execute "python light-locker-settings.py"
