I'm trying to launch Google Chrome with dark mode enabled using Selenium WebDriver in Python, but I'm having trouble getting the add_argument method to work. Here's the code I'm using:


from selenium.webdriver.chrome.options import Options
from selenium.webdriver import Chrome
import time

chrome_options = Options()
chrome_options.add_argument('--force-dark-mode')

driver = Chrome(options=chrome_options)
time.sleep(5)
driver.quit()

When I run this code, it launches Google Chrome, but dark mode is not enabled. I've also tried using the --force-dark-mode-on but they didn't work either.

I'm using Google Chrome version 78, which should support the --force-dark-mode option. I'm not seeing any error messages or warnings in the console or logs.

What could be causing add_argument not to work for enabling dark mode in Google Chrome with Selenium WebDriver? Are there any other options or workarounds that I can try?

Chrome in dark mode

Not sure about Google Chrome version 78 but using Selenium v4.10.0 with / ChromeDriver v114.0 can be enforced using the argument:

options.add_argument('--force-dark-mode')

  • Code block:

    from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--force-dark-mode')
options.add_argument("start-maximized")
driver = webdriver.Chrome(options=options)
driver.get("https://www.google.com/")

  • Browser snapshot:

dark_mode

Web components in dark mode

Auto for web contents can be enforced by using the argument:

options.add_argument("--enable-features=WebContentsForceDark")

  • Code block:

    from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("--enable-features=WebContentsForceDark")
options.add_argument("start-maximized")
driver = webdriver.Chrome(options=options)
driver.get("https://www.google.com/")

  • Browser snapshot:

enable-features=WebContentsForceDark

fix above code :

chrome_options.add_argument("--enable-features=WebContentsForceDark")

and this is my command in chrome://version

Command Line:

/usr/bin/google-chrome-stable --flag-switches-begin --enable-features=WebContentsForceDark --flag-switches-end --desktop-startup-id=gnome-shell/Google Chrome/some-info
