How do you set up a headless display on AppVeyor for Windows builds? This process is straightforward for Linux on all other CI services but I am having no luck implementing a solution for this on AppVeyor with windows.

On linux with Travis, its as simple as:

      - xvfb

before_script: # configure a headless display to test plot generation
  - export DISPLAY=:99.0
  - which Xvfb
  - Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 &
  # - ls -l /etc/init.d/
  # - sh -e /etc/init.d/xvfb start
  - sleep 3 # give xvfb some time to start

What would be an equivalent for windows?

Particularly, I want to get the open-source library vtki running in this way. Currently, we skip over half the library's test on windows because we haven't been able to figure this out.

Any help would be greatly appreciated!

    Fix it. See this repo of helpers:

    Add these two lines to the install script and it works!

        - "git clone --depth 1 git://"
        - "powershell ci-helpers/appveyor/install_opengl.ps1"
