Thanx a lot, I'll try it as soon as 6.7.196 makes it into the Ubuntu
repository (it's not that terribly urgent as to make self compilation
But I have to admit some confusion: The docs
explain the option as:
} Enable load detection on the TV DAC. The TV DAC is used to drive both
} TV-OUT and analog monitors. Load detection is often unreliable in the
} TV DAC so it is disabled by default.
In my case, the analog output VGA-0 is connected to an analog projector and
is detected and driven w/o problems. Can't I then conclude from the above
that the TV DAC is running already? So how does the option "know" to switch
on load_detection on the output DVI-0?
