wierd keyboard problem

[Michael P. Conlon]

Greetings!
	I hope this is the right place to ask this question; I looked in all the 
usual places (FAQ, x.org, ubuntu.com, Google, etc.) to no avail.

	I am running the latest Kubuntu Linux. Last week, when I was running Kubuntu 
9.something, one day my keyboard stopped working under X. (I have a PS/2 
keyboard, 32-bit Athlon processor, 256 Mbytes of RAM.) I soon discovered that 
the keyboard worked just fine in the console, and for the KDE login, but I 
could not enter text into any window or widget after login. Also, pressing 
numlock or capslock does not illuminate the indicator lights.

	After fiddling with it for several days, I downloaded the latest Kubuntu 
(10.10) figuring that it was time for an upgrade anyway. After installation, 
the keyboard worked fine for one day. Second day, I was back to the same 
problem: console input just fine, but no response once logged into X. I tried 
both another PS/2 keyboard and a USB keyboard. The system wouldn't boot 
(kernel panic) with the USB keyboard; the PS/2 keyboard exhibited the exact 
same problem as the original one. My xorg.conf file is rather sparse, and it 
doesn't mention the keyboard.

	Is there a configuration file somewhere that might effect this? I presume it 
must be an X problem since the keyboard works fine in console mode. I am hoping 
that I have a corrupted configuration or initialization file somewhere that I 
could fix. Or, is it possible to have a keyboard hardware failure that would 
affect X but not the console, and that could be temporarily fixed by a new 
installation?
