	I recently posted a question about this problem, and received no expert 
responses. In my case, I did a Kubuntu reinstall, and the keyboard worked 
after the first bootup, but not on subsequent reboots. I have not experienced 
the alternation between working mouse and working keyboard. 

	The keyboard works fine if the system is in console mode, so the problem 
has to be with X. Both mouse and keyboard have PS/2 interfaces.
