Ubuntu Detects 2 monitors when I only have 1. This causes an issue when booting up because it's detecting 2 monitors and by default it is mirroring the display; which is causing a distorted picture since it's trying to create a mirror image on 1 display. xrandr output.... The VGA1 is the phantom monitor and I need to remove it so it boots to LVDS1 and NOT mirrored.
Any suggestions on how to permanently remove VGA1?

This seems to be an issue with certain motherboards that have an HDMI and a Display Port. I figured out that either my Gateway ZX6800 Touch-Screen is using a certain Laptop motherboard with the on-board Intel HD chipset that supports this or it is seeing the IR Blaster or TV Tuner and driving it as a monitor.
Either way the fix is: Edit /etc/default/grub add "video=VGA-1:d" between the quotes in the GRUB_CMDLINE_LINUX line update-grub
Look in /sys/class/drm for a list of your computers outputs.Mine was labelled as "card0-VGA-1". Just remove the "card0-" and that's the name of the output in question.
