Ummm...  Okay, what do you know that I don't?

I fixed the input problem by setting "AcceptEmptyInput"
appropriately[1].

Now, I have two other problems I'm trying to
track down, either of which could be related to
using Intel graphics:
  * On logout, screen dies (garbage all over).
    /var/log/messages reports that the Xorg server
    died with a segfault; I presume this left the
    graphics card in a bad state.  Alt-Ctrl-F1 changes
    the garbage on the screen but doesn't recover the
    screen.
  * If I start kdm from /etc/ttys, I get a blank
    screen on startup.  If I start it from a root
    login, it works okay for the first login.

Still digging...

Tim

[1] If I understand correctly, "AcceptEmptyInput"
is now mandatory if you are not using hald and
forbidden if you are.  Is there a reason for
the Xorg server not to set it automatically?
