如何解決Python selenium在遠程shell下無法連接瀏覽器的問題？

Ubuntu16+Python2.7，代碼如下：

from selenium import webdriver
browser = webdriver.Firefox()
browser.get("http://www.163.com/")
print browser.title
browser.close()

在圖形界面下運行正常，用ssh遠程連接的時候就報如下錯誤：

Traceback (most recent call last):
File "spider.py", line 25, in &
browser = webdriver.Firefox()
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 145, in __init__

Google上查到上面這個鏈接，一樣的問題但是並沒有回答~有大神了解么，摯謝。

sudo apt-get install xvfb
sudo pip install pyvirtualdisplay

然後代碼修改為：

from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(1024, 768))
display.start()
browser = webdriver.Firefox()
browser.get("http://www.ubuntu.com/")
print browser.page_source
browser.close()
display.stop()

剛好最近折騰了，嘗試以下幾個方案：

』1.使用phantomJS這種無界面的瀏覽器

2.使用virtualDisplay，如@當年少輕狂 所說

3.在圖形界面中建立一個screen的session，然後ssh遠程過去在該session中跑，瀏覽器會在該圖形界面的屏幕顯示。
