signal(SIGUSR1, signalHandler); ?</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">signal() is deprecated, according to its manpage. "man signal" even says:
The behavior of signal() varies across UNIX versions, and has also var-
ied historically across different versions of Linux. Avoid its use:
use sigaction(2) instead. See Portability below.</pre>

sigaction(SIGUSR1, &sa, NULL); // for later nullptr
i doubt that you'll need another update for that, though.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Well, should I change it?
In kscreensaver/libkscreensaver/main.cpp they used sigaction() as well.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">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.

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">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.
