Same issue to me, my laptop is ASUS A53S, with nVidia Geforce GT 520MX.
Right now I'm using only HDMI connected monitor because the laptop monitor is a
decoupled mirror of the HDMI connected monitor.
Here is xrandr output with HDMI monitor plugged in:

Bug description:
SRU Request
Systems with Optimus (Intel+NVIDIA GPUs) can have ghost VGA devices
hardcoded in the BIOS. This leads the system into thinking that there
is actually one more active output than there really is.
[Impact]
* The ghost VGA output confuses lightdm and the gnome-settings-daemon making
the system unusable.
[Test Case]
* Install the nvidia binary driver, reboot, and check the output of the
"xrandr -q" command
- Expected: only the outputs that are actually connected will be marked
as active.
- Bad behavior: a non-existent VGA device will show up in the output.
[Regression Potential]
* Low, as it only disables CRT outputs in the nvidia driver.
[Other Info]
* N/A

There is a non existent display detected in both intel driver only and nvidia
331 driver installation.
The non existent display is "Unknown Display" shown in gnome-control-center
--> display and "CRT-0" in nvidia-settings, and "VGA-0" in xrandr -q output.
It will cause gdm failed to start. gnome-shell has some crazy layouts.
lightdm will only occupy 2/3 of monitor in top left corner.
I tested this in intel driver only environment. and nvidia-331 installation
environment.
My laptop is Asus U36JC. My monitor correct resolution is 1366x768.
The following is the output of "xrandr -q" in gnome-shell with
nvidia-331 installed:

Note: this Unknown non-existent display happens in intel driver only
environment TOO. If required, I can provide "xrandr -q" output with
that environment. At present, I don't bother to remove/purge my
nvidia-331 installation.
Please let me know if anything else is required. Thank you very much!
