kdm preventing cgminer from accessing 3rd GPU

This is really quite strange, but I'm wondering if someone else has run into the same problem.

I typically run KDM to start my KDE session.  I have the following setup:
KDE with kwin
3 AMD 290Xs using fglrx (Crossfire disabled)
3 portrait mode monitors

If I use a xinitrc file and use 'startx' to start my KDE session, cgminer can see all 3 GPUs just fine using:

cgminer -n

However, if I start with KDM, I only see two of those GPUs.  Any ideas what is causing this?
