Since version 0.19, Kerbal Space Program includes a native Linux version. However, only Ubuntu 12.04 is officialy supported, so it may not work on Arch Linux out of the box.


Install kerbalspaceprogramAUR[broken link: archived in aur-mirror] from the AUR or install it in Steam client if you bought steam version of the game.

Known issues

Game never progresses past initial loading

To fix this, set:


This is also relevant if your rocket's parts do not connect.

Game SegFaults before launching, v1.1+

The Unity 5 engine expects you to be running PulseAudio. You can install pulsenomoreAUR from the AUR or download it from [1] ,the KSP bug tracker, as a workaround until this is fixed by the Unity devs.

No text display

The game requires Arial and Arial Black fonts, provided in the ttf-ms-fontsAUR AUR package.

Another alternative is to try to use ttf-freefont, from the official repositories. This worked using KSP 0.90.0 on x86_64 Arch Linux. YMMV

In-game menus are blank, v1.1+

Some resolutions cause menus to appear empty. Try using your settings.cfg file to enable fullscreen and/or change your resolution by a few pixels, e.g. 1366x768 to 1363x768.

Imperfect resolutions can cause poor font rendering. If this happens you can use the AnyRes mod to change your resolution in-game to find a good one, rather than launching the game for every change.

Another solution that may work on some architectures is to add -force-glcore as a launch option, or passed in as a command line flag. For Steam, go to: Library -) right click on KSP -) Proprieties -) Set up launch options and add -force-glcore The game engine will try to run the game with the best OpenGL version possible and all available OpenGL extensions. With this option enabled you may encounter shadow glitches, try few different settings in-game in the setting panel to resolve the problem.

Graphics flickering when using primusrun

Run with PRIMUS_SYNC=2 (but you will get reduced frame rate this way)
