Virtual Monitor Linux

Virtual Display Linux (VDL Monitor)

I'm using this simple script for extend my desktop pc to "2 external monitor" via teamviewer.

Device support

Curently this VDL Monitor only work for intel CPUs with integrated graphics only, sorry 😞

If you are using an Nvidia GPU, you can follow this instruction.

Or if you already made a mistake when trying this script on a device without an integrated intelhd gpu, which makes your device stuck on a black screen with blinking cursor, this instruction might be useful for you to fix this problem.

If you encounter a similar problem, you just need to delete /usr/share/X11/xorg.conf.d/20-intel.conf created by vdl-monitor to get your device booted normally again.

Quick Setup

  1. Install teamviewer on both devices. (You also can use VNC to)
  2. cd ~
  3. git clone https://github.com/dianariyanto/virtual-display-linux.git
  4. cd virtual-display-linux
  5. sudo chmod +x vdl-monitor
  6. Change your own resolution setup vdl-monitor.conf
  7. ./vdl-monitor
  8. For first running, you will prompt to reboot or relogin current session
  9. cd ~/virtual-display-linux/
  10. ./vdl-monitor
  11. Done.
