Any suggestions?
I have a dual head set up using xrandr on an openbsd machine and it was rather painless. I will offer more dets if you'd like (eg, my xorg.conf), but I just googled, and found http://www.jejik.com/articles/2008/10/setting_up_dual_monitors_system-wide_with_xrandr_on_debian_lenny/ , which looks helpful.
