I got the exception(below) when running Selenium with chrome driver version 74 on Linux server. It’s running just fine on Windows

unknown error: Chrome failed to start: exited abnormally (unknown error: DevToolsActivePort file doesn't exist) (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

I can prevent this error by adding "--headless" into ChromeOptions, but some elements cannot be found when run Selenium with headless mode. my current ChromeOptions use as example below.

options = new ChromeOptions();
options.addArguments("--no-sandbox");
options.addArguments("--disable-dev-shm-usage");
options.addArguments("--user-data-dir=something");
options.addArguments("--start-maximized");

I am Linux beginner, Can someone help me to know is it possible to run headful Selenium on Linux server and also how to do it?

you should find all the elements in headless mode as well. do you have an example of what you can't find? - Adi Ohana
@AdiOhana The element that missing in headless mode is a div element, I select by xpath(something like *//div[@id='xxx']). After I use headless Firefox instead of chrome(still run on Linux), selenium can found every elements that I need. However, it will be useful to know what is the issue of headless chrome and Is it possible to run heedful in Linux as well. - wittakarn
it is possible to run Chrome with selenium webdriver on a Linux machine with GUI, tough it is a bit complicated, I once did it following this article: tecadmin.net/setup-selenium-chromedriver-on-ubuntu if you can share some HTML examples, I can help try figure the headless Chrome issue - Adi Ohana
Chrome is located in one of four places on Linux. Are you finding/using the Chrome executable? My Python code to drive Chrome in a headless config uses this to locate Chrome. Then is sets options.binary_location = get_chrome(). - jww

I can suggest you reinstall your chrome and use WebDriver Manager, with which you do not need to indicate the location of the binary file: for Java - https://github.com/bonigarcia/webdrivermanager for Python - https://github.com/SergeyPirogov/webdriver_manager
