weblogic installation unable to instantiate GUI, defaulting to console mode

Installing WebLogic 10.3.6 on Centos minimal installation from terminal using x-forward results in "installation unable to instantiate GUI, defaulting to console mode"

$ java -jar wls1036_generic.jar
$ Unable to instantiate GUI, defaulting to console mode.

We can of course do the installation in console mode.
To fix the gui issue we need to install libXtst using yum

$ sudo yum install libXtst.x86_64 -y

After installation is running in GUI mode as expected.
