 options = Selenium::WebDriver::Options.chrome(args: ['--headless=new'])
 driver = Selenium::WebDriver.for :chrome, options: options
 driver.get('https://selenium.dev')
 driver.quit

My rspec configuration that (finally, actually) works:

  before :all do
    ## Works, non-remote : )
    # Capybara.default_driver = :local_selenium_headless
    # options = Selenium::WebDriver::Options.chrome(args: ['--headless=new'])
    # @driver = Selenium::WebDriver.for :chrome, options: options

    ## works, remote : )
    Capybara.default_driver = :remote_selenium_headless
    options = Selenium::WebDriver::Options.chrome(args: ['--headless=new'])
    options.add_argument("--remote-debugging-port=9222")
    options.add_argument("--window-size=1400,1400")
    @driver = Selenium::WebDriver.for( :remote, {
      url: "http://#{SELENIUM_HOST}:4444/wd/hub",
      options: options,
    })
  end

Yes, I've sometimes run it locally, and sometimes on a remote selenium grid. Both ways must work for me.

Just for reference, `require 'capybara_helper'` file contains the following:

Capybara.register_driver :local_selenium do |app|
  options = Selenium::WebDriver::Chrome::Options.new
  options.add_argument("--window-size=1400,700")
  Capybara::Selenium::Driver.new(app, browser: :chrome, options: options)
end

Capybara.register_driver :local_selenium_headless do |app|
  options = Selenium::WebDriver::Chrome::Options.new
  options.add_argument("--headless")
  options.add_argument("--window-size=1400,1400")
  options.add_argument("--disable-dev-shm-usage")
  Capybara::Selenium::Driver.new(app, browser: :chrome, options: options)
end

Capybara.register_driver :remote_selenium do |app|
  options = Selenium::WebDriver::Chrome::Options.new
  options.add_argument("--window-size=1400,700")
  options.add_argument("--no-sandbox")
  options.add_argument("--disable-dev-shm-usage")
  options.add_argument("--remote-debugging-port=9222")
  Capybara::Selenium::Driver.new(
    app,
    browser: :remote,
    url: "http://#{SELENIUM_HOST}:4444/wd/hub",
    options: options,
  )
end

Capybara.register_driver :remote_selenium_headless do |app|
  options = Selenium::WebDriver::Chrome::Options.new
  options.add_argument("--headless")
  options.add_argument("--window-size=1400,1400")
  options.add_argument("--no-sandbox")
  options.add_argument("--disable-dev-shm-usage")
  options.add_argument("--remote-debugging-port=9222")
  Capybara::Selenium::Driver.new(app, {
    browser: :remote,
    url: "http://#{SELENIUM_HOST}:4444/wd/hub",
    options: options,
  })
end
