"Possible fix" should be "Possible Workaround" and I forgot to add that
I rebooted afterwards. I've now been running in Dual Head mode with s
1024x768x16 screen and a 1280x1024x16 screen without any problems for
over an hour now. I've tried MPlayer, Firefox, Firefox + Flash 7.0 r63,
Firefox + MPlayer Plugin, a couple 3D Screen Savers, and so far no
problems whatsoever.
FYI, I've included my xorg.conf below. This is a lightly modified
version from the one that was generated during the install to run a dual
head configuration. Primary screen is the laptop and secondary is the
monitor.
