Bug Description
To reproduce the bug:
1. Login by SSH to an Ubuntu 16.04 server
2. Run tests from https:/
Result:
Most of Horizon tests use the fixture 'video_capture', which is trying to get os.environ[
> raise KeyError(key)
E KeyError: 'DISPLAY'
Expected behaviour:
* Check if the *requirements* are suitable to use the *video recorder*. Show the link to the documentation/
* It would be nice to have an additional example in the documentation to avoid such errors on CI:
"E WebDriverException: Message: Can't load the profile. Profile Dir: /tmp/tmpw6BEat If you specified a log_file in the FirefoxBinary constructor, check it for details"

It's obvious, that Horizon dashboard requires a browser, a browser requires graphic display (X11 on linux). Without X11 display horizon tests can't be launched. If X11 display is present the environment variable `DISPLAY` is defined.
With patch https:/
* "Environment variable `DISPLAY` is undefined. Can't determine X11 display to capture video. Be sure that you have installed X11 display or xvfb. More details in http://
* "`avconv` is not found on current system. Be sure that you have installed `avconv` to capture video. More details in http://
