Hi Matt,
Thanks for the tip about indented children, very useful. Here are the
results (neither the xdm by itself, nor the ttys xdm will exit, as
either user or root). BTW, this isn't just wmaker, it does the same
thing with fvwm, twm, or cwm (the three other ones I tried). I didn't do
the process evaluation on any others than wmaker, but the behavior (not
returning to xdm) is the same.
Thanks,
Will
