I started testing the 64 bit rpms of 2.2.2-pre2 on openSUSE 10.3 with an 
MGE Ellipse 1500 USB.  Here is my writeup of the test, with my apologies 
for a long post.  It looks as if I have a problem with upssched.

My 64 bit rpm's are available at

Hello Kjell, I guess that there would be some configuration, for example 
to say after what interval shutdown would start, and to specify the 
shutdown command.

For me power monitoring should, like justice, not only be done but be seen 
to be done: I have gotten used to the screen display provided by 
mgeups-psp so I installed nut-2.2.2-pre2.x86_64.rpm and mgeups-psp-3.0.4-2

There is no /var/state in openSUSE 10.3, so I changed PIPEFN and LOCKFN to 
/var/run and defined directory /var/run/ups.

And now, flags waving and fireworks for the grand opening:

glacon2:~ # rcupsd start
Starting NUT UPS drivers             done
Starting NUT UPS server              done
Starting NUT UPS monitor             done

There is no sign of action by mgeups-psp, no window, no icon.

glacon2:~ # ps aux | grep ups
upsd  16455  16484 1004 ? Ss /usr/lib/ups/driver/usbhid-ups -a mgeups
upsd  16459  14328  720 ? Ss /usr/sbin/upsd -u upsd
root  16462  16168  696 ? Ss /usr/sbin/upsmon
upsd  16463  16592  816 ? S  /usr/sbin/upsmon

I wonder why upsmon is running twice?
In YaST2 -> System -> System Services (Runlevel) I set upsd 
"Enabled" and restarted the machine for a clean test. 
After restart, in /var/log/messages I see

The directory /var/run/ups is empty. the command upsc reports:

I disconnected the UPS from the wall and upsc reported
   ups.status: OB DISCHRG
but there is no notification of an impending shutdown and no shutdown.
In /var/log/messages, I see

Directory /var/run/ups is still empty.  It looks as if I have a problem 
with upssched - any help would be much appreciated.
