Leave everything at zero except for the one being t= ested. But these also seem unlikely, as it's a hardware signal from the vid= eo board to the monitor.

For example, a cron job. Just as a data point, I had the same thing happen on PC-BSD 9.0.

Never filed a bug report, since I didn'= t know if it was FreeBSD, PC-BSD or X.org. OK, MCN=
