three different power managers

[pol]

Hi all,

My laptop happen to have installed three different power managers:
 1. klaptop
 2. "power manager"
 3. kpowersave

Surely they are conflicting, so I need your help to uninstall two of them.
I have been told that klaptop is the oldest and unmaintained one. Yet
uninstalling klaptop rised unknown issues that changed the xorg.conf file,
without any warning. 
I would keep kpowersave only, but i cannot quit "power manager", which
restarts at every new session. I have unistalled guidance-powersave, but
nothing has changed. 
Any suggestions?

By the way, how is that no warning has been issued, as the user was 
installing conflicting packages?

Thank you for you help
