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
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,
Swap: 2064376k total, 248892k used, 1815484k free, 183344k
Looks like double to me.
What else would make these things go haywire, especially
behind a KVM switch?
