[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 ( 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.
