Forwarding this bug from a Ubuntu reporter:

This hardware has an SVideo output, and on boot xrandr reports the TV output as enabled when nothing is connected to it.  As a result, plugging in a monitor or projector via VGA fails to work, requiring manually disabling the TV output first.

[Original Report]
This laptop has an S-Video output, and when booting it enables the TV output for it, even though nothing is connected. This is a problem because if connecting to an external monitor or projector via VGA, it requires several additional steps to make it work.

As a workaround, I can manually disable the TV output, and then enable the VGA output. This can be done using the xrandr command line tool, but there is no mechanism for doing this just with the GUI screen resolution tool, so it won't be obvious for most users.

Please attach log with ModeDebug on. XorgLog.txt showed correct detect result as TV is disconnected, attached wrong log?
