Does anyone have a foolproof way of preventing kdm_greet using
100% CPU in version 4:3.5.13-0debian9+r1261450+pr19~squeeze ?

We have:

# grep -i sak /etc/trinity/kdm/kdmrc
UseSAK=false

but still we see 100% CPU usage on some (but not all) laptops
after power up before login.  Laptops are running 30°C hotter
with kdm_greet running 100%, resulting in occasional failures.

TIA,
