Description:
---------------------
In our opinion, xrandr can only detect the plugged display pipe, but Baytrail
machine can print VGA information without been plugged. Add command
"video=VGA-1:d" in grub, we can disable VGA and xrandr will display correctly.
Both 32bit and 64bit machine reproduceable. This issue exists on older kernels,
it's not a regression.</pre>
