It seems that due to the trouble you’ve had in the past that your setup is non-standard, not that there really is a standard when it comes to Linux, unfortunately.
You can look at Coreform 202x Segmentation faults (Ubuntu 18.04) for an example of someone else with a similar issue. I suggested that they use a Xephyr window, which is a way to host graphical applications in a custom environment on the same machine.
