It seems imac pannel doesn't like whe we change the hot plug setup and then refuse to work. This help but doesn't fully fix: https://bugzilla.redhat.com/show_bug.cgi?id=726143
How does it help? Does it fix the the aux problems, but the monitor still doesn't train? What's the working value of the relevant DC_HPD*_CONTROL register?
