when the screen is unlocked by the user during the grace time. But apparently this \
can leave behind running screensaver processes launched by the greeter, see the bug \
report (which has the highest number of  votes of all open bugs AFAICS).

This patch changes this to only terminate the greeter, and adds a signal handler to \
the greeter to exit gracefully in this case. The signal handler exits with return \
code 1, so that it is not possible to circumvent the password input by just sending a \
SIGTERM. (the screen locker restarts the greeter in case it doesn&#39;t quit with \
exit code 0)</pre>  </td>

Monitor-&gt;Screen Locker, be sure to leave &quot;Require Password after&quot; \
disabled. Wait for the screen locker to kick in.
Unlock the screen by moving the mouse or pressing a key.
Check the process list.

Without this patch at least kswarm.kss and kblankscreen.kss reliably kept running \
after unlocking the screen on my system. With this patch they quit themselves.

I&#39;m using this patch for over two weeks now, and I haven&#39;t seen any left-over \
screen saver processes any more (and I even set the timeout to 1 minute).

I also tried to terminate kscreenlocker_greet manually by running &quot;killall \
kscreenlocker_greet&quot; from a text console in case of a password required, and the \
locker didn&#39;t quit, you still have to enter the password.</pre>  </td>
