My notebook is connected to a HDTV through a KVM Switch (one other notebook also connected to the same HDTV). The problem seems to be that Ubuntu doesn't recognize the HDTV to be turned on and therefore doesn't enable the VGA output. As far as I understand it has something to do with EDID information not being send trough the KVM Switch.
xrandr won't enable the VGA output through
xrandr --output VGA1 --auto, it just keeps showing as disconnected.
Can I somehow force the VGA port to send a signal?
