i just HDMI-connected a gateway flat panel display to my f12 laptop,
and configured the display to span. in short order, i got the
standard f12 desktop background to display on the flat panel and, yes,
i can move the cursor off the right-hand side of my laptop and watch
it magically appear on the left-hand side of the flat panel.
the problem is, the flat panel keeps blanking -- literally every
several seconds -- and then comes back. does this output from xrandr
look reasonable?

640x480 72.8 75.0 66.7 60.0

the setup seems correct, except for the persistent blanking.
thoughts?
