This minimal code works suggesting headless=True should work in OS: Debian GNU/Linux 12 (bookworm) x86_64

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

options = Options()
options.add_argument("--headless=new")
options.add_argument("--no-sandbox")
options.add_argument("--disable-dev-shm-usage")

driver = webdriver.Chrome(options=options)
import time
time.sleep(50)

But only headless2/xfvb works

[mdmintz]

Then just use headless2 - problem solved!
That probably means your VPS has an older version of Chrome that has 2 headless modes.
headless just uses the default one, and headless2 uses the newer, stealthier one.
On newer versions of Chrome, there is only one headless mode (the stealthier one), so it wouldn't matter.
