Reviving power management features after kubuntu update.

logind.conf

##########################
#  /etc/systemd/logind.conf was recently changed to intercept and 
#  eat power events (like laptop lid closing) BEFORE kde has a 
#  chance to act on them.  Rendering System_Settings->Power_Management->Energy_Savings 
#  settings useless.  The following settings should fix it.
