Yeah, it's checking to see if you have anything connected to the TV
output. To do that, it needs to temporarily unplug the VGA.
You can avoid this by ignoring the TV output
Option "Ignore" "True"
Option "monitor-TV" "TV"
If your machine cannot ever have a TV adapter (even with a docking
station), we can add a quirk to the driver to never look at the TV
output. That requires the pci subsystem values (from lspci -n -v) to
plug into the quirk table.
