I try and take good notes setting things up, but all I have is "doesn't
work on secondary head". My memory is that I saw a reason why it
doesn't work on the secondary head but my Googling isn't finding that
right now. Oh, maybe it's because I'm using Xinerama.

After starting X, there should be a "direct rendering enabled"
message in the X server startup log. Please note that DRI isn't
enabled if you're using the Xinerama extension. You may want to
keep two "XF86Config" files on hand -- one for DRI and the other
for DualHead.
Hum, that just talks about DRI, not OpenGL.
On my main head I get about 200fps with glxgears. On the second head
the window goes black and my machine gets very slow.
BTW -- I also get:
(EE) MGA: Failed to load module "mga_hal" (module does not exist, 0)
My guess is I upgraded my kernel at one point and didn't move over that
module. I thought that was for Matrox's PowerDesk, which I don't have
installed.
The HAL library is not required for basic DualHead support
(without a DVI monitor)"
Which is my case.
