I am running into this with KDE desktop.  Exact symptoms.  The keyboard 
is dead and I cannot do anything.  Even the Caps Lock key doesn't work. 
  Num lock does work.

I tried to kill processes from a ssh but had no success.

No process loads to indicate where the problem is.  Nothing to report to 
assist in a bug report.

What desktop are you running out of curiosity?

I have nVidia on an older system.  I have not run into this with my 
64bit system.

I have not had a lockup for a few days but before I get into a video 
editing session (when my lockups are normal), I log out and back in.  It 
seems to work great.

You do make a point about the changes.  It seems that most of the 
lockups are when I make quick changes to the applications.

Any hints on what to look for via strace or what application to look at?
