So, I tried Allen's xorg.conf file, but I didn't see anything that was
different from what I was doing, and I created an .xsessionrc that
seems to do the right thing.  However, I'm STILL having DVI blanking
problems.

What I've noticed is that switching desktops brings it back, and
sometimes it comes back all on its own.  So, here's my theory: Could
it be a synchronization problem?  When I had the totally wrong setup,
I got the same effect (screen blank with no picture).  Since the time
before blanking is variable, I'm thinking this is the problem.

But I can't seem to find a spot in the Xorg log file that says "I'm
clocking horizontal and vertical at these speeds".  So, any (more)
clues out there?

Thanks.
