Comment 39 for bug 1232454

@ChemDroid
I just understand your way to do won't kill the silly popup when you unlock the session just between the moment when the popup araises and the moment when the pc goes to sleep.
It seems to me that the best killer trigger remains the moment when we enter the password.
Assumed Carsten comment, I think I'll switch back to the use of wmctrl which seems to target more precisely the "Energy" pop-up, although I'm completely ignorant and unskilled if this window title is used elsewhere.
I tried here ( https://forum.ubuntu-fr.org/viewtopic.php?pid=15709961#p15709961 ) to use wmctrl -ci 0x..... but I had bad behaviour, wmctrl killed other windows when it didn't find the exact win id.......

https://bugs.launchpad.net/ubuntu/+source/wmctrl/+bug/1266273 shows either a real bug in wmctrl or just that I'm a real newb patcher.
