截屏的硒脚本无法在终端上运行，并且无法启动chrome浏览器

Question

我的目标是在硒终端上运行带截图的selenium脚本，正常代码可以轻松地在Ubuntu终端上运行，但是如果我运行带截图的代码，则无法正常运行

代码：

System.setProperty("webdriver.chrome.driver", "/home/dev2/Downloads/newchromedriver/chromedriver");
        WebDriver m = new ChromeDriver();
        m.get("");
        m.manage().window().maximize();
        m.findElement(By.xpath(".//input[@id='user']")).sendKeys("");
        m.findElement(By.xpath(".//input[@id='pass']")).sendKeys("");
        m.findElement(By.xpath(".//button[@id='login_submit']")).click();
        m.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
        // m.manage().timeouts().implicitlyWait(2,TimeUnit.MINUTES);

        m.switchTo().frame("mailFrame");
        Thread.sleep(9000);
        String row=m.findElement(By.xpath(".//tr[contains(@id, 'rcmrow')]")).getText();
        System.out.println(row +"\t");
        if(row.contains("ADC: Reminder 3. GENERAL ENQUIRY REQUEST - Qa Hemant Three") && row.contains("Tue")) {
            System.out.println("mail recieved");

        }
        else {
            System.out.println("mail not received");
        }
        String timestamp = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss").format(new Date());
        String imgname = "mapscreenshot " + timestamp + ".png";
        String fileWithPath = "//home/dev2/Desktop/" + imgname;
         Screenshot fpScreenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(m);
         ImageIO.write(fpScreenshot.getImage(),"PNG",new File(fileWithPath));

        System.out.println("your screenshot is saved at location: " + fileWithPath);


**Terminal output:**

/eclipse-workspace/seffcon$ java -cp /home/dev2/eclipse-workspace/seffcon/bin:/home/dev2/eclipse-workspace/seffcon/libs/* org.testng.TestNG testng.xml

我希望Chrome浏览器可以打开，脚本应该可以截屏 但这没有发生
