Error: GDK_BACKEND does not match available displays; Running Selenium using Crontab

I am trying to run selenium using cron.

import os from selenium import webdriver from selenium.webdriver.firefox.options import Options from pyvirtualdisplay import Display from selenium.webdriver.common.desired_capabilities import DesiredCapabilities firefox_capabilities = DesiredCapabilities.FIREFOX firefox_capabilities['marionette'] = True firefox_capabilities['handleAlerts'] = True firefox_capabilities['acceptSslCerts'] = True firefox_capabilities['acceptInsecureCerts'] = True binary = webdriver.firefox.firefox_binary.FirefoxBinary("/usr/bin/firefox") now = datetime.datetime.now() print "* Time of RUN : ",now display = Display(visible=0, size=(1024, 768)) # display.start() browser = webdriver.Firefox(firefox_binary=binary,executable_path=os.getcwd()+'/geckodriver') browser.get('http://www.google.com') print browser.title browser.quit() # display.stop()

Following is the error displayed in geckodriver.log

1525859641163 geckodriver INFO geckodriver 0.20.1 1525859641167 geckodriver INFO Listening on 1525859642167 mozrunner::runner INFO Running command: "/usr/bin/firefox" "-marionette" "-profile" "/tmp/rust_mozprofile.1xUlJhxoO4Ar" Error: GDK_BACKEND does not match available displays

things I tried:

<ol> <li>tried running selenium without display (pyvirtualdisplay) i.e headless selenium</li> <li>tried binary parameter while invoking webdriver.firefox() </li> <li>tried geckodriver excutable(linux) in webdriver.firefox() </li> <li>used export Dispaly=:0; in the cron cmd</li> </ol>


<ol> <li>

update latest geckodriver

</li> <li>

download latest firefox tarball and follow this step

</li> </ol>


3.Install the official Firefox Beta PPA

$ sudo apt-add-repository ppa:mozillateam/firefox-next

4.Run apt-get update

$sudo apt-get update <ol start="5"> <li>

Install firefox and xvfb (the X windows virtual framebuffer) packages

$ sudo apt-get install firefox xvfb </li> <li>

Run Xvfb in the background and specify a display number (10 in my example)

$ Xvfb :10 -ac & </li> <li>

Set the DISPLAY variable to the number you chose

$ export DISPLAY=:10 </li> <li>test the code #!/usr/bin/env python from selenium import webdriver browser = webdriver.Firefox() browser.get('http://iAisystem.com/') browser.quit()</li> </ol>

firefox if you download as tar it helps to avoid download dependency files

wget http://ftp.mozilla.org/pub/firefox/releases/61.0/linux-x86_64/en-US/firefox-61.0.tar.bz2

Note your firefox code should have headless option inorder to avoid displaying window.
