 	Hmmm ... I got to something telling me the commonest 
reason was lack of permission. But the link to the forum didn't 
find that, the apparent link to a FAQ isn't, and I can't tell, 
from the list of users that usr/bin/system-config-users brings 
up, what group I might have to add myself into. Is there a way to 
ask that app what a given group does? Properties doesn't tell 
you.

         I did get into the power manager (I think it was) via GUI 
about the time I replied first, and tried to turn off all that 
good stuff. I *think* I succeeded -- which is the lesser evil 
while only this PC is booted.

         The screensaver was still running when I got home from 
the shoulder surgeon, three hours later; and also this morning. I 
won't try putting it back behind the KVM switch for a while yet.

 	Iirc, they were before I whomped up on them with the big 
hammer, just telling everything "never."

         But I'd prefer to make the stuff work right, if that 
isn't a big project, just because this beast *is* meant for a 
server, and the fans are so powerful they tend to whine whenever 
it does anything.

 	Btw, I was advised under the list that suspending 
required a swap file double the size of memory. Top gives :

         Mem:   1026108k total,   962440k used,    63668k free, 
110468k buffers
Swap:  2064376k total,   248892k used,  1815484k free,   183344k 
cached

         Looks like double to me.

 	What else would make these things go haywire, especially 
behind a KVM switch?
