Actually i am trying to run a headless browser in remote debian server through selenium. I have firefox 46.0.1 installed in the server and i am using selenium 2.53.1 version.
Whenever i tried to run a given test i got the following error.
org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(/usr/bin/firefox) on port 7055; process output follows:
Error: GDK_BACKEND does not match available displays
I have instantiated firefox driver in my code like this:
saDriver = new FirefoxDriver();
can anyone help?
I am not familiar with Java. However in Python this issue can be solved by the following method, this may help you
If it says Error: GDK_BACKEND does not match available displays then install pyvirtualdisplay:
pip install pyvirtualdisplay selenium
You might need xvfb too:
sudo apt-get install xvfb
Then try adding this code:
from pyvirtualdisplay import Display
display = Display(visible=0, size=(800, 600))
display.start()
Full example:
from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(800, 600))
display.start()
browser = webdriver.Firefox()
browser.get('http://www.python.org')
browser.close()
display.stop()
