Doing that right now, and posting from that machine. The problem
is not even mitigated.
What's more, I ran system-config-display again, logged out, and
logged back in. No change. It came up saying generic LCD, set to
1280x1024, but only actually offering 1024x768 -- on a monitor that's
really 1680x1050. I changed that to HP w2207, but it made no difference.
Detail, which I meant to mention before, in case it tells anyone
anything. Sometimes (I can't tell how to characterize the times), every
movement of the cursor leaves a trail of tiny dots behind it. When it
does, they persist even if I open a new app. They're barely perceptible,
except in case they're right over a word or line of text (which is
already way undersized as well as pale & faint); then they make that line
or word all but illegible.
Section "Monitor" of xorg.conf contains the settings :
ModelName "LCD Panel 1280x1024"
HorizSync 31.5 - 64.0
VertRefresh 56.0 - 65.0

Two other details : this is the oldest machine in the house,
bought used from a guy who was eager to get in on the then- emerging 64-
bit systems, whenever that was. lshw-gui says it's an ASUS A7V8X, with an
AMD Athlon(TM) XP 2200+ cpu motherboard
I discovered when my previous lcd flat panel died suddenly and I
had to buy this one that both the problem machine and the next oldest
were physically incapable of handling 1680x1050; but, fortunately, HP's
engineers had foreseen that, and the w2207h has software of its own that
will stretch out 1280x1024 to an acceptable display -- if only I can get
back to that. (It was doing so till I forgot that while upgrading --
thanks to a lot of help here, particularly from Frank Cox iirc.)
I hope one of those details may tell one of you something.

I have precious (very precious!) little idea where up is.
