[PLUG] power management suddenly stops working at login screen

[Greg Helledy <gregsonh@gra-inc.com>]

I use Kanotix 2005-04, which uses x.org, kernel 2.6.14 (kanotix' own 
special version of course) and kdm as login manager.

Until recently, while at the login manager, the monitor would 
automatically go to suspend after 10 minutes or so.  This has suddenly 
stopped happening, without me having upgraded anything or edited any 
config files.

If I do a "xset dpms force off" the monitor does go into its suspend 
mode (power light goes from green to orange).  When a user is logged in, 
the suspend choice in the Control Center works normally.

Following the instructions I found here:
http://gentoo-wiki.com/HOWTO_Automatically_turn_off_your_monitor

I tried adding this to /etc/X11/xorg.conf:
---------------
Section "Monitor"
    Option "DPMS"

Section "ServerLayout"
    Option "OffTime" "20"
---------------

I did not have a "Section "ServerLayout"" and adding that produced 
errors, so that X would not load.

Anyone else ever dealt with this?
