Virtual Monitor for Ubuntu

Running UBUNTU on a computer without a monitor and accessible via VNC will generally just give a BLACK blank screen.

A virtual dummy monitor needs to be created.

Using command line:-

sudo apt-get install xserver-xorg-video-dummy

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):

  Section "Device"


     Identifier  "Configured Video Device" 

    Driver      "dummy"

     # Default is 4MiB, this sets it to 16MiB

     VideoRam    16384

 EndSection 

 Section "Monitor"

     Identifier  "Configured Monitor" 

    HorizSync 31.5-48.5 

    VertRefresh 50-70 

EndSection 

 Section "Screen" 

    Identifier  "Default Screen" 

    Monitor     "Configured Monitor" 

    Device      "Configured Video Device" 

    DefaultDepth 24 

    SubSection "Display"

     Depth 24 

    Modes "1024x800" 

    EndSubSection
