slim (simple login manager)

[Derek Tracy]

I tried installing slim last night to see if I could get it to work.  I
think there is a bug in slim, I tried editing the prefdm file along with
Xclients, I can get slim to start from command line and all is well but no
go from system startup.

Does anybody know the xauth command line slim uses when it is starting up?
