mystery X lossage

[Rob Mayoff]

| If I log in from another machine and kill off every process that might
| have an X connection, the keyboard doesn't come back, so the problem is
| not something stupid like "some random program is grabbing the keyboard
| and not letting go."  It can be wedged when the only X program running
| is the X server itself.

When you log in remotely, run "kbd_mode".  It should say raw (scancode)
mode.  If it doesn't, that would be the problem.
