I could, but that's different from the failures I'm sure of. Those
involved switching to a different user in an *already existing* session.
So, the sequence is
KDM running on vt7
login as user A
switch user | start a new session
KDM running on vt8
login as user B
switch user | back to existing session for A
back as user A on vt7, switch user to existing session for B
More specifically, sometimes vt8 flashes up briefly, then the session on
vt7 is killed and control returns to vt7. It shows the kdm greeter
after the reset is done.
When the dead session is on vt8 I think you get just a blank screen
(i.e., vt8 still showing--but kdm doesn't ordinarily show anything on
In practice, there has always been intervening actions and time between
the steps. Sometimes it works OK.
It's possible sometimes the vt7 would be killed at the initial start of
a new session on vt8, but I'm only sure the problem has happened as

Thanks for the pointer.
