Review request for kde-workspace, Plasma and Aaron J. Seigo.


Bugs: 327947 and 329076

Repository: kde-workspace


Description
-------

If the screen locker is set to not require a password to unlock, it will not show the password input field even when the powermanagement settings suspend the system and are set to require a password after resume (when it was already running at that point).
This locks people out of their system.

This patch adds a signal handler for SIGUSR1 that switches the running greeter to immediateLock mode. The locker sends that signal to make sure the greeter shows the password input field when necessary.

Testing
-------

Disable "Require password after" in the screen locker settings (the default), set it to start after 1 min. (for easier testing).
Enable "Suspend session after" and set it to 2 minutes. (set the action to "Suspend", "Hibernate", or "Lock Screen", doesn't matter)
Make sure "Lock screen on resume" is enabled in the powermanagements "Advanced Options" (it is by default).

After 1 minute the screen locker kicks in, and doesn't require a password.
After 2 minutes the session gets suspended, hibernated or locked, and requires a password to resume.

Without this patch no password dialog is shown, the user cannot resume the session by entering the password.

With this patch this works: there is a password input field, the session is unlocked when the user enters the password.


Thanks,

Wolfgang Bauer
