Xorg log

The output monitor detection failed as it detects a TV monitor when no TV is plugged.
The VGA output modes are also incorrectly detected when a VGA monitor is plugged in.

As en attachement the Xorg.log and xrandr output when nothing is connected.

Thank you for taking this into consideration.

I also would like if someone can provide me some information (intel specifisations and a way to have more debug output from the intel driver) to resolve this bug myself if no one has time to look at it.

Bye
