Introduction

This documentation describes the optimal setup and configuration of X-Plane under Linux. It is aimed at Linux-experienced users and assumes a working Linux installation.

The guide covers the most important aspects of system optimization, including kernel configuration, driver optimization, and performance tuning. In the area of X-Plane setup, optimal configuration, performance settings, and hardware integration are addressed. Additionally, extensions such as addon integration, plugin configuration, and setting up a development environment are described.

The examples shown here are based on Debian Linux but can be easily transferred to other distributions. The basic concepts and procedures remain the same - only the specific package manager commands or repository configurations need to be adjusted accordingly.

Why X-Plane?

X-Plane stands out from other flight simulators through its simulation-oriented approach. The realistic flight simulation is based on Blade Element Theory, which enables real-time flow simulation. Instead of pre-made tables, real-time flight physics calculations are performed, supported by detailed simulations of engines and aircraft systems as well as precise weather simulation with atmospheric effects.

In the professional field, X-Plane finds widespread use in flight schools and pilot training. There are certified versions for professional simulators that are also used in research and development. These versions form the basis for FAA-certified training devices.

The graphical representation in X-Plane follows a unique approach. Unlike typical simulators, the focus is on physically correct light representation and realistic rather than artistic interpretation. The base representation is plausible and can be extended through addons. Technically, this is implemented through PBR for realistic material representation, dynamic lighting, atmospheric effects, real-time reflections, and HDR rendering.

The adaptation and development of X-Plane is supported by an open Plugin architecture and extensive development tools. External flight models can be integrated, and the simulation engine is regularly updated. An active developer community supports continuous development.

Currently, there are some limitations, such as performance limitations due to the Single-CPU architecture, with multi-core support in development. The system configuration is more complex than with other simulators, and optimal use requires a longer learning curve.

Why X-Plane under Linux?

Linux as an operating system offers special advantages for X-Plane. Performance optimization enables precise control over CPU and GPU resources, minimal system latency through adapted kernel configuration, efficient memory usage, and optimized driver support for graphics hardware.

The stability and reliability of the system is ensured by the absence of automatic updates or background processes during flight. System performance is predictable without unexpected drops, and robust error handling enables long runtimes without performance degradation.

Hardware integration benefits from direct hardware access without additional abstraction layers. Flight simulator-specific peripherals are optimally supported, and multi-monitor setups can be flexibly configured. The use of VR hardware is particularly efficient.

For development and adaptation, extensive development tools for X-Plane plugins are available. The direct integration of development and debugging tools enables easy automation of X-Plane processes and flexible scripting options for complex workflows.

While X-Plane also runs under Windows, Linux enables more precise control over system resources and a more stable runtime environment. The higher initial effort is balanced by better performance and reliability.

Sources on Xplane (see link below) describe the installation on a running system. However, the goal of this documentation is to install the Linux system itself and optimize it for Xplane, thus going far beyond a simple Linux installation.
The Debian distribution was chosen as we want to start with a non-optimized system and then optimize the individual layers
