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

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

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.

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

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?
