[![semantic-release](https://img.shields.io/badge/%20%20%F0%9F%93%A6%F0%9F%9A%80-semantic--release-e10079.svg)](https://github.com/semantic-release/semantic-release) [![renovate-app badge][renovate-badge]][renovate-app]

### Usage

```javascript
var Xvfb = require('xvfb');
var options = {}; // optional
var xvfb = new Xvfb(options);
xvfb.start(function(err, xvfbProcess) {
  // code that uses the virtual frame buffer here
  xvfb.stop(function(err) {
    // the Xvfb is stopped
  });
});
```

The Xvfb constructor takes four options:

* <code>displayNum</code> - the X display to use, defaults to the lowest unused display number >= 99 if <code>reuse</code> is false or 99 if <code>reuse</code> is true.
* <code>reuse</code> - whether to reuse an existing Xvfb instance if it already exists on the X display referenced by displayNum.
* <code>timeout</code> - number of milliseconds to wait when starting Xvfb before assuming it failed to start, defaults to 2000.
* <code>silent</code> - don't pipe Xvfb stderr to the process's stderr.
* <code>xvfb_args</code> - Extra arguments to pass to `Xvfb`.
* <code>onStderrData</code> - Function to receive `stderr` output

### Debugging

Run with `DEBUG=xvfb` environment variable to see debug messages. If you want
to see log messages from the Xvfb process itself, use `DEBUG=xvfb,xvfb-process`.
