[K12OSN] Re: K12OSN] SCREEN_01 contains a screen script ldm

you need the lts.conf so the client knows where to start graphic
sessions by running ldm (or even startx) or to start a terminal. You are
getting the same screen that a default session with proper lts.conf
would get on ctrl+alt+f1

lts.conf is now located in 

If you don't have one, here's enough to get you started:


    # LDM_DIRECTX=yes allows greater scalability and performance
    # Turn this off if you want greater security instead.
    # LDM_DEBUG=yes writes to /var/log/ldm.log during client runtime
