This is my experience getting Little Navmap working with my simulator running on Proton. I created this account specifically just to post this to help people who are migrating their sims to Linux.

 

My setup:

• DISTRO: Arch Linux
• DE/WM: Hyprland
• SIM: MSFS2020 Steam running via Proton

 

Prerequisites:

1. Download the Linux .tar.gz version of LNM. Not the installer.
2. Download the Windows .zip version of LNM from the github repo. Not the installer.
3. Extract both separately in a convenient directory (we'll use ~/LittleNavmap/Linux and ~/LittleNavmap/Windows for this guide)
4. Install protontricks from your preferred package manager. (https://github.com/Matoking/protontricks)

 

Solution:

1. Launch your simulator
2. Execute this command in your terminal

   protontricks -c "wine ~/LittleNavmap/Windows/Little Navconnect/littlenavconnect.exe" 1250410

3. Wait for the Little Navconnect window to show up

4. Launch the Linux version of LNM

5. Tools > Connect to Flight Simulator... > Hostname: 127.0.0.1

6. Wait for LNM to connect to LNC

7. Profit

 

Optionals: 

• (optional) Create a .desktop shortcut for the Linux executable of LNM (~/LittleNavmap/Linux/littlenavmap)
• (optional) Create a .desktop shortcut for Little Navconnect using the protontricks command (~/LittleNavmap/Windows/Little Navconnect/littlenavconnect.exe)

 

Notes:

• Running the Windows littlenavmap.exe directly via protontricks does work, but for me the UI is too laggy/sluggish maybe because of the additional Wine layer.
• If your sim runs on Wine in a custom prefix, this solution should theoretically work with winetricks. Just make sure you set the pfx to your sim's wine prefix directory.
• If you're still having trouble, reply here and describe your issue and I may be able to help you.

 

 

 

 

Thanks for the help! I suppose this is needed if you also run a MS simulator on Proton? Otherwise you can use one of the native LNM builds.

Yep! I guess this guide is just for sims running on Proton/Wine. Although I haven't tried any Linux native sims yet like XP12/11, people won't need this guide since the native linux builds should work without any extra effort.

@kabaww Thanks for sharing your solution. I got LNM working fine, the only thing is that LNM apparently can't find the scenery library database. Unlike Windows, I can't load the scenery library since no simulator is found. Is that normal or an error?

Install the Windows version of LNM in the Proton environment and then generate the scenery library databases.
You can copy the databases to the Linux installation then.

You can treat the Proton and Linux installations like two separate computers. https://www.littlenavmap.org/manuals/littlenavmap/release/latest/en/NETWORK.html
