Whats the next step up in display manaagers from lightdm for a pi 3b?

[Gene Heskett <gheskett@shentel.net>]

Greetings all;

That is the question unless someone can tell me how to make lightdm work 
with a 24 bit framebuffer on a pi 3b.  The default of 16 bits blends too 
many colors into one box. X is starting the server, but except for a 
mouse pointer. I can right click, which brings up a very simple menu, 
from which I can call up a terminal, and from there I can run things, 
and even the limited color looks way better than it did on a 12 bit 
screen.

Thanks all.

Cheers, Gene Heskett
