You can easily find out.  Connect the "problem machine" directly to the
monitor -- remove the KVM switch from the circuit.

See if the problem goes away.

If the problem goes away, the KVM switch is the problem.

If the problem doesn't go away, the KVM switch isn't the problem.

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
        Option      "dpms"
[....]
Section "Device"
        Identifier  "Videocard0"
        Driver      "radeon"
[....]
Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
        EndSubSection
        SubSection "Display"
                Viewport   0 0
                Depth     16
                Modes    "1280x1024" "800x600"
        EndSubSection



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.

These are the steps which work for me:
- system->admin->display->hardware
	set to generic LCD of the right size
	log out
- system->admin->display->settings
	now you should be able to set the max resolution
	log out
- system->prefs->hardware->ScreenRes
	now you should be able to set what you really want
	log out

That works for me, although it feels very "Windows-ish" to keep logging out.
Note: works on FC9 & FC10, similar works on FC11, but that system is in use and I can't play right now.
