Hi,
I found, that the management tool (login configuration from within control
center) for config kdm, creates the wrong user "Root" (with upper case
"R")
in kdmrc, if one selects, that only root can shut down the computer.
Than the computer just stops with a console I have to login as root and
powerdown the machine.
So it is at least only a typo.
System: Debian wheezy with trinity 3.5.13
