My /etc/init.d/kdm creates a /var/run/_x_dm.pid!!!

[Raimund Eimann]

Hi,

my /etc/init.d/kdm creates a /var/run/_x_dm.pid and the /var/run/xdm.pid 
contains kdm's PID (!)

what I did: I took Knoppix 3.3, removed all of KDE (3.1.2 or 3), compiled 3.2 
myself. Runs nicely, except for the weird KDM startup script issue.

When I removed KDE,  I no longer had a /etc/init.d/kdm file, so I took the 
existing xdm file in this directory and adapted it, amongst other things I 
set PIDFILE=/var/run/kdm.pid, but still it's creating an xdm.pid...    :(

Below I've attached the entire file... can anyone help me with this?

Cheers,
Raimund
