Jmeter Chromedriver error: unknown error: DevToolsActivePort file doesn't exist when executed from remote master machine

Question

I'm trying to execute WebDriver sampler script from JMeter with WebDriver plugin and chrome-driver installed . The JMeter is configured to work in distributed mode. I currently have 2 nodes, one Master and one Slave. My script resides on master machine and I'm trying to execute it from Master machine using below command.

$JMETER_HOME/bin/jmeter -n -t recorder1.jmx -r

I receive this error:

JMeter-Server runs under ubuntu user on Slave instance. I execute my test from Master machine also with ubuntu user. I saw that if chromedriver is executed with superuser it can cause the same issue like I have, but it's not the case.

The strangest thing is that if I execute the same script in headless mode it works fine. Also if I execute the same script from GUI or from command line on slave machine it also works fine without errors.

Installed:

EC2 instance with Ubuntu 18.04
apache-jmeter-5.1
ChromeDriver 2.45.615355
jmeter-plugins-webdriver-3.0.jar

Any ideas?

I also saw possible solution in: org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist while trying to initiate Chrome Browser

It's recommended there to add this code:

System.setProperty("webdriver.chrome.driver","pathto\\chromedriver.exe");    
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(options);
driver.get(url);

but how do I change chromedriver options before is is initialised in Chrome Driver Config step in JMeter?

According to what I see at ChromeDriver downloads page:
```
Supports Chrome v70-72
```
so make sure that Chrome version installed in Ubuntu is in the supported range
Given the OS is Ubuntu server it should not have GUI while Chrome requires a DISPLAY to run at, either real or virtual. In both cases you should have DISPLAY variable defined and pointing to the real or virtual display.
So first of all log into the machine exactly as you when running JMeter slave and launch /usr/bin/google-chrome as ubuntu user. If it starts without issues - you should be good to go, if not - you will need to fix the browser launching prior to attempting to use it from JMeter. You can double check the result of browser execution by verifying exit status - running the next command:
```
echo $?
```
if you see 0 - you're fine, if not - you have a problem.

Dmitri T, Thanks a lot for your response! Regarding #1: I have chrome version 72.03626.121 — Fred Shniper, Mar 11 '19 at 13:38
Thanks a lot for your response! Regarding #1: I have chrome version 72.03626.121. I tried to change chromedriver to chromedriver=72.0.3626.69, it gives me the same results. #2,3 I have VNC/X11 installed on the machine. It opens chrome browser if I execute `/usr/bin/google-chrome` command while I'm in VNC screen. — Fred Shniper, Mar 11 '19 at 13:44
