It is NOT the window manager, it is not kde, I repeat it is NOT the
window
manager. I use GNOME, kde, AfterStep, Windowmaker, fvwm, fvwm95, and
xfce, and
have had related problems in ALL of them.
I believe that the problem is that a buffer somewhere is not getting
flushed
correctly and the data is getting corrupted, it has nothing to do with
SMP or UP,
however on SMP machines it seems to occur more often with APIC-edge
triggered
interrupts, but this is not exclusive, as it will ocur on APIC-level
too, and also
XT-PIC, and on UP machines as well/
If you have a PS/2 mouse and you loose your keyboard it is because the
PS/2 mouse
is usually on the keyboard controller, and once you loose one that
buffer is
hosed, if you can get out of X and reset the buffer you ..
This does not happen on the console (AFAIK) thou which also uses the
mouse and
keyboard, so I am leaning towards an X bug rather than a kernel bug, or
possible
that the kernel is corrupting buffers and then X gets a corrupted
buffer..
your keyboard problem is not unique especially if you have a PS/2 mouse,
but I am
not sure how to reset that....
