Linux Keyboard Problems - Bizarre

Okay. First, let me give some introductory information.

I ripped down my setup tonight so that I could put in the new desk that I purchased. After getting the desk assembled and into place, I carefully pieced back together my setup, taking great care to make sure everything was set up correctly. The relevant parts of the setup are as follows:

1 Dual Athlon box running Red Hat Linux 7.2
1 PowerMac Dual Processor running MacOS X 10.1.5
1 Belkin OmniView SOHO 4 port KVM switch with USB
1 Microsoft Natural Keyboard to KVM switch
1 Logitech Wingman Gaming Mouse, USB, to Dual Athlon
1 Microsoft Intellimouse Explorer, USB, to PowerMac

The boxes are sitting side by side, as can be seen in this picture:

Note that the monitors zig-zag - I prefer to have Linux on my left and MacOS on my right, though I wanted the boxes the other way around.

Anyway, the keyboard goes in to the KVM. This is the only device that I use the KVM switch for. There is a USB cable coming out of the KVM switch and going to the PowerMac. There is a Belkin KVM cable kit running from the KVM to the Linux box. I only have the PS2 keyboard cable plugged in - the others are just hanging.

The mice are each hooked directly in to their respective computers, as are the monitors.

This setup was working for me before I tore down the setup.

Now, here is the problem:

After booting, <b>the keyboard will not work</b> on my Red Hat box. Will not work period.

Here's the more bizarre part - it works <b>during</b> boot up. I can enter interactive mode, tell things to start, others to not... but after boot, it doesn't work. Period.

It is <b>not</b> the KVM. I have plugged this keyboard <b>and</b> another which I know to be functional directly in to the PS/2 keyboard port on the motherboard. The exact same symptoms exist.

It now seems that by turning off GPM, I have gotten the keyboard to work in console mode. BUT... it will still not work in X! I checked my XF86Config's and they haven't been changed for 4 and 6 months! Even more strange, XFree86.0.log doesn't seem to show anything wrong.

So where are we as of current? The keyboard doesn't work in X but works everywhere else. startx and then kill it? Yep, keyboard works in console. It just stops working in X. Num Lock, Caps Lock, all that shit... doesn't work. Nothing. It's as if the keyboard is being disconnected when X is running.

I am baffled. I don't know what to do. This is pretty much rendering my very main machine useless.

Any ideas? Anyone?
