Topic: Linux and crashes
Azimuth is a Windows program, so on Linux it runs through Proton. The FH2MP launcher is a native Linux app and sets Proton up for you.
What you need
•Steam with Proton 11 (any Proton 11 build, including GE-Proton). Older Proton versions and the system Wine usually fail with "Your graphics card or driver is not supported".
•A GPU with DirectX 12 support through Vulkan (any recent AMD, NVIDIA or Intel GPU with current drivers).
Setup
1. Download the AppImage or .deb from the releases page. On Steam Deck, do this in Desktop Mode.
2. For the AppImage, make it executable: chmod +x FH2MP-Launcher-*.AppImage, then run it.
3. Follow the setup. On Set up Linux support, the launcher picks Proton and a prefix and installs the shader compiler Azimuth needs. Use Change Proton settings only if it can't find Proton.
4. Press PLAY.
Starting through Steam instead
If you prefer to start Azimuth as a non-Steam game, keep the FH2MP launcher open (it signs you in) and set these launch options in Steam:
WINEDLLOVERRIDES="winmm,dwrite,d3dcompiler_47=n,b" %command%Set the compatibility tool to Proton 11. Without the overrides, Extra Options, the Mod Platform and FH2MP don't load and online stays locked.
On some AMD systems the game only starts from Steam; the launcher tells you when that's the case. See Graphics card or driver not supported on Linux.
Mods on Linux
Most mods work. A few don't:
•Streaming radio mods can't use a native Linux browser. Use the music-folder source. See [Radio mods](/tutorials/radio-mods).
•Old versions of some mods needed Windows-only files (for example Achievements 1.0.0). Update them.
Logs
The launcher log is in ~/.cache/fh2mp/launcher.log. The game's logs are in the Azimuth folder, as on Windows. See Which logs to send.
