Does the Raspberry Pi version have TDM, or are we stuck with
lightdm?
        

  
But, try tdm-trinity or tdm as a name, instead of lightdm.
    

Probably dumb questions, but what is a display manager needed (VS
used) for, and what are the relative merits (lightdm VS tdm)? I don't
seem to have any DM's installed. If lightdm uses less system
resources, does it follow that not using a DM uses even less?
First, there are no dumb questions...
I'm running the Wheezy version, with Trinity desktop. By default, Wheezy only boots to the command prompt, then you have to type "startx" to go graphic, and that bypasses any display manager.  When it's set up to go directly to graphics, (done in /etc/inittab), it will then use a graphical password menu. By default it uses lightdm. blahhh.  Now I'm not sure about any memory usage "trapped" when X actually starts. seems to me it should be just another layer in the system stack/pointer thats not running. If true then TDM should act the same.

Just my thoughts......
