Cant log in from external monitor on laptop with broken screen.

Hello. I am installing Kali Linux on a laptop with no monitor. The installation goes fine through the external monitor and I can see the GRUB menu on boot, but once it comes time to log in it acts like my non existant laptop screen is my main monitor to type my login info on while my external is just grey background. Moving the mouse cursor it will appear from the left hand side of the screen and I can enter the ctrl alt f3 terminal and log into root. Search engine results seemed 'xrandr' in the terminal could help me select my external monitor as the main one through terminal or boot commands. But when I type it in it says "Cannot show display" I checked the xrandr --help and tried other commands to the same effect. Wont even list displays with xrandr -q. Also built in laptop FN display commands only make the screen flash for a millisecond. Also checked BIOS for any video settings that I could change, there is nothing. I also tried logging in blind by typing passphrase, return key, also tried return, passphrase, return, no effect. I know if I can log in blind I can right click the background and select the graphics options from the shell to mirror the displays. If anyone can help me with a solution or you need any additional information please respond I would greatly appreciate it.

xgamma

xgamma(1)						      General Commands Manual							 xgamma(1)

NAME

       xgamma - Alter a monitor's gamma correction through the X server

SYNOPSIS

       xgamma [-display display] [-screen screen] [-quiet] [-gamma f.f | [[-rgamma f.f] [-ggamma f.f] [-bgamma f.f]]]

DESCRIPTION

       xgamma allows X users to query and alter the gamma correction of a monitor via the X video mode extension (XFree86-VidModeExtension).

       Note that the xgamma utility is obsolete and deficient, xrandr should be used with drivers that support the XRandr extension.

       If no value for the gamma correction is given via the -gamma or -rgamma/-ggamma/-bgamma options, xgamma prints the current gamma correction
       of the display.

OPTIONS

       -display display
	       This argument allows you to specify the server to connect to; see X(7).

       -screen screen
	       When multiple displays are configured as a single logical display, this option allows you to select the screen you wish to change.

       -quiet  Silence the normal output of xgamma

       -help   Print out the `Usage:' command syntax summary.

       -gamma f.f
	       The gamma correction can either be defined as a single value, or separately for the red, green and blue components.  This  argument
	       specifies the gamma correction as a single value.

       -rgamma f.f
	       This argument specifies the red component of the gamma correction.

       -ggamma f.f
	       This argument specifies the green component of the gamma correction.

       -bgamma f.f
	       This argument specifies the blue component of the gamma correction.

ENVIRONMENT

       DISPLAY To get default host and display number.

BUGS

       This  client  changes the internal values of the gamma correction for the Xserver. Whether or not these values are respected depends on the
       video drivers.

       The gamma values are passed to the Xserver with 3 decimal places of accuracy.
