是否需要在Linux机器上为无头firefox浏览器设置DISPLAY

Question

I want to run the headless browser and below is the code for same. However when i ran it. it shows "Error: no DISPLAY environment variable specified"

try {
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("webdriver.log.driver", "INFO");
profile.setPreference("webdriver.log.file", targetDir + File.separator + "firefoxSeleniumServer.log");
profile.setPreference("browser.download.folderList",2);
profile.setPreference("browser.download.manager.showWhenStarting",false);
profile.setPreference("browser.helperApps.neverAsk.saveToDisk","text/csv;text/plain");
if(platform.equalsIgnoreCase("linux")) {
DesiredCapabilities desiredCap = DesiredCapabilities.firefox();
profile.setPreference("browser.download.dir",System.getProperty("user.dir")+ File.separator + "target");
System.setProperty("webdriver.gecko.driver", "/test/geckodriver/geckodriver");
System.setProperty("webdriver.firefox.bin","/usr/bin/firefox/firefox");
desiredCap.setCapability("headless", true);
driver = new FirefoxDriver();
}

However when i set the display it shows unable to open firefox on DISPLAY:99

Also i tried setting the xvfb as well. But that also did not work.

As i am using gekco driver here, do i need to do some more configurations.

I think you are supposed to provide the DesiredCapabilities object as a parameter to the FirefoxDriver constructor:
