I'm guessing some device is injecting 60 cycle into your system

don't think it's your monitor going bad, although I've never seen this

I moved my computers around again and "reclaimed" my previous desktop computer,
the one that I was using up until I got this one. Now the problem appears to
be gone. I'm pretty sure it's something flaky about the onboard video in the
new computer -- this monitor seems fine when it's hooked back up to the other
computer.
If the problem is caused by a "beat frequency" issue then the frequency
of the video would be part of the problem and another computer might not
show it. I was hoping that moving the monitor itself would change the
problem, indicating it was interference. And because at one point you
thought changing the cable fixed it, I was hoping that the offending
device was off at that time, and when back on started the problem
again.You said you moved the computer with respect to the monitor, did you
just move the monitor around?
I actually moved the computer from under my desk to under a table that's
a few feet away and around a corner. Which was handy when I moved my
"old computer" back in here because I just put it back where it sat
before.
OK, if the monitor was moved without changing the problem then that
makes the interference less likely. I usually just rotate the monitor
ninety degrees and see what that does. ;-)

I actually had about half of my apartment and office rewired about two weeks
ago. I re-did the ceiling tile in the kitchen and it seemed to be the opportune
time to rationalize and update the wiring. But that was two weeks ago and the
problem didn't show up until this Friday when I hooked up my new computer.
More and more, it appears that the problem is in the new computer. I shall see
what I can round up in the way of a video card tomorrow (today is a holiday
here so the computer store is closed) and then go from there.
I'm thinking that I should try an ATI card due to their new "open source"
policy. My experiences with Nvidia cards on Linux were several years ago and
were uniformly bad. Things may have changed since then (maybe) but I still
have bad feelings about it. I still like the onboard Intel stuff because it
just works right out-of-the-box on a Linux install -- no drivers to fiddle
with or anything. But that may not be an option in this situation.
Did you try changing the frame rate with the "video=" boot option?
I did put F8 on a Dell laptop for someone a couple of months ago. It had an
ATI-something-or-other video chipset and it just worked too, somewhat to my
surprise.
I suppose what I end up with will depend largely on what Garry has on the shelf
in his shop at the moment. Does anyone have any recommendations?
I'm an ATI fan as well, for the most part they just work.
