[kde-linux] keyboard freeze under 3.5.5

[Paul Kaplan]

I've been having my keyboard freeze up under kde 3.5.5 running on kubuntu 
(either Dapper or Edgy).  It didn't happen under 3.5.4.  It seems to happen 
randomly about every 3-4 weeks, but I probably just haven't discovered the 
exact conditions.

The mouse remains functional and commands all are accessible but I can't do 
any keyboard input.  The problem is restricted to kde since it doesn't happen 
under other window managers, under kdm, or on a terminal login.

The only solution I've found is to delete ~/.kde and allow it to rebuilt 
during login, so clearly there is a file or files that is/are getting 
corrupted.

Has anyone experienced such a keyboard only freeze?  Is there a known fix?
TIA
