My message was a bit misleading, I am afraid. I mixed up some things in
The proposed "maybe-solution" would only work with newer cards following
the OpenPGP Card standard (v3.1). I am not sure if you would like to use
this for a general purpose screen locker. Thus, I guess the solution
that Werner proposed is much better (killing scdaemon when locking the
screen), especially because I think it is working for all cards that
make use of poldi. So this would be a more general approach. Did you
already think about that solution?
