I am on Windows 11. I have already setup Windows version of VisualVM and able to perfectly run it without any issues. I wanted to try the Linux flavour. I setup sdkman, java, and maven. But for some reason I am unable to run visualvm successfully.

I think the issue is that libXtst.so is not available in Ubuntu 22. Ubuntu uses all lowercase letters or so I heard. But I am unable to troubleshoot further and fix the problem. I tried all Java 8, 17 and 21. I have even set flags manually: visualvm --jdkhome=/home/ahroo/.sdkman/candidates/java/17.0.9-amzn

I have added version details below.

I ran visual with console output. Perhaps this could help:

I think the issue is that libXtst.so is not available in Ubuntu 22.

On a Ubuntu 22.04.3 LTS system, following the suggestion in How do I find the package that provides a file? reports that that libXtst.so is provided by the libxtst6:amd64 package:

$ apt-file find libXtst.so
libxtst-dev: /usr/lib/x86_64-linux-gnu/libXtst.so
libxtst6: /usr/lib/x86_64-linux-gnu/libXtst.so.6
libxtst6: /usr/lib/x86_64-linux-gnu/libXtst.so.6.1.0

Suggest try sudo apt install libxtst6 to install the package, and see if:

  1. That allows visualvm to run.
  2. Or changes the error message to report a different missing dependant shared library. In which case the above example of using apt-file find to search for the package which provides a specific shared library, should allow you to locate and install the package which provides the shared library.
