This behaves that way on purpose--when useSAK=true and tsak cannot be
enabled (i.e. when uinput is not loaded) the checkbox is not checked to
avoid the appearance of tsak being permanently enabled.  If this is
confusing then we will need to find a better way to indicate this.

I never really thought about this, but I guess this might be a correct way
of looking at it.  My original thought was that if someone killed tsak,
all users would know that the system was compromised as the Ctrl+Alt+Del
screens would not appear or function.  Automatically restarting tsak might
make more sense, but TDE's design doesn't make this particularly easy.

The desktop lock seems to be rather badly messed up in general.  I need to
figure out what happened to cause this; it probably broke in my earlier
attempts to convert it to a persistent process.
