====== Add Fake Display when No Monitor is Plugged In ======


Basically install a dummy driver:

<code>apt-get install xserver-xorg-video-dummy</code>

Then write it in the /usr/share/X11/xorg.conf.d/xorg.conf (or possibly /etc/X11/xorg.conf) file (create one, if it does not exist):

===== **IMPORTANT!!! Set Up remote desktop FIRST!** =====

 * Before changing xorg.conf file, set up remote desktop server first, like "RustDesk" and create backup of original file. 

<code>Section "Device"
    Identifier  "Configured Video Device"
    Driver      "dummy"
    # Default is 4MiB, this sets it to 16MiB

EndSection

Section "Monitor"
    Identifier  "Configured Monitor"
    HorizSync 31.5-48.5
