[GRLUG] X11 Multi monitor question

I'm using KDE for my setup. I had two monitors working in Suse just 
following the instructions from Nvidia but I'd rather not go back there 
unless I have to.

I tried and loved fluxbox on a live cd (seemed oh so fast and lite). 
First thing I tried was getting that via apt on a bare Debian install. I 
missed a couple things and in my attempts to get X working, installed 
KDE hoping it would take care of that and can't switch back. But I don't 
care much about that till I fix the multi monitor setup.

For the most part... once I get the x config right, window managers 
won't matter much will they? As far as basic usability?

Lets get the wiki going!!! I can install one for us if you change the 
DNS to point there (64.141.135.25)... wiki.grlug.org? If we don't index 
it in google, might not even have to worry about wiki spam till we get 
further down the road.
