Review request for kde-workspace and Plasma.


Changes
-------

Another update to reflect the changes in RR#117091


Bugs: 224200
    http://bugs.kde.org/show_bug.cgi?id=224200


Repository: kde-workspace


Description
-------

Currently the screen locker just kills the greeter (kscreenlocker_greet) 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't quit with exit code 0)


Diffs (updated)

Diff: https://git.reviewboard.kde.org/r/117644/diff/


Testing
-------

Configure a legacy screensaver in Systemsettings->Display and Monitor->Screen 
Locker, be sure to leave "Require Password after" 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'm using this patch for over two weeks now, and I haven'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 "killall 
kscreenlocker_greet" from a text console in case of a password required, and 
the locker didn't quit, you still have to enter the password.


Thanks,

Wolfgang Bauer
