### Expected behavior I downloaded the latest binary and tried to run Jmeter. However I got the error as described in actual behaviour. Expected behaviour was - Jmeter GUI should open. ### Actual behavior ankur@ankur:~/software/apache-jmeter-5 (1).5/bin$ ./jmeter ================================================================================ Don't use GUI mode for load testing !, only for Test creation and Test debugging. For load testing, use CLI Mode (was NON GUI): jmeter -n -t [jmx file] -l [results file] -e -o [Path to web report folder] & increase Java Heap to meet your test requirements: Modify current env variable HEAP="-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m" in the jmeter batch file Check : https://jmeter.apache.org/usermanual/best-practices.html ================================================================================ An error occurred: **No X11 DISPLAY variable was set, or no headful library support was found, but this program performed an operation which requires it,** ### Steps to reproduce the problem system information  My display variable is also set - ankur@ankur:~/software/apache-jmeter-5 (1).5/bin$ echo $DISPLAY :1 I am using dual display, is that the issue? ### JMeter Version 5.5 ### Java Version openjdk version "19.0.1" 2022-10-18 OpenJDK Runtime Environment (build 19.0.1+10-Ubuntu-1ubuntu122.04) OpenJDK 64-Bit Server VM (build 19.0.1+10-Ubuntu-1ubuntu122.04, mixed mode, sharing) ### OS Version Ubuntu 22.04.1 LTS -- This is an automated message from the Apache Git Service.
