[Solved] Black Screen At Startup

I successfully installed arch to my laptop.  It was booting to the command line.  Then, in an attempt to run lightdm and xfce, I installed lightdm, lightdm-gtk-greeter, xfce4, and xfce4-goodies.  I did not make any changes to any config files.  If I understand correctly, lightdm should use lightdm-gtk-greeter by default.

Now, when I reboot the machine, the screen goes black.  When I hit Ctrl-Alt-F2 I am able to log in at the command line.  How do I troubleshoot this?

My monitor was powered off and connected to the laptop.  If I power on the monitor, then it works - I get duplicate graphics on the laptop and the monitor.  If I disconnect the monitor, then the laptop display works.  For some reason, if the monitor is powered off and connected, then the laptop screen goes black.
