Comment 54 for bug 779166

@cgonzalez and anyone else:

Since the screen also goes dark when resuming from suspend or other purposes, and rc.local doesn't get run at that time, I've also added the relevant setpci command to root's crontab, to be executed every minute. That way, the screen isn't black for more than a minute.

(I might add that the machine affected belongs to a non-technical friend of mine who doesn't want anything complex.)
