Supported Operating System

- Linux: “While X-Plane 11 will run on Linux, we don’t provide support for specific distributions; if you want to run on Linux, you will need to try X-Plane on your distribution to see if it is compatible. With that in mind, we have developers using Ubuntu 14.04 and 16.04 LTS successfully. For Linux, we require the proprietary driver from AMD or NVIDIA to run X-Plane. You may be able to get X-Plane to run on the Mesa/Gallium driver with an Intel GPU, but this is unsupported. We absolutely do not support the fully open source drivers for AMD and NVIDIA.”
Even the minimum requirements are quite steep; As to why this is so we do not know. X-Plane 11 is expected to be released later this month. And just as a reminder if you purchase X-plane 10 from their website you can get X-plane 11 for free.
