Dual Screen blank on resume

Hey!

Suspend and resume on my HP laptop works fine unless I have another monitor plugged in. If I suspend and resume when the laptop is plugged in to a second monitor then the fan starts going but the screen remains blank.

Strangely pm-suspend.log doesn't seem to show a resume event, here's the log from the last crash:

usr/lib/pm-utils/sleep.d/99video suspend suspend: success.
