My Garry’s Mod Addons Aren’t Showing Up (Linux Naming Fix)

On a Linux server, Garry’s Mod is picky about addon folder names due to case‑sensitivity.

🚫 What Breaks On Linux?

• Uppercase letters (e.g. Gas-Config won’t work)
• Spaces, punctuation & special characters
• Folder names must be all lowercase and no spaces

✅ Valid Naming Rules

• Use lowercase only
• Use hyphens (-) or underscores (_) — both work fine on Linux
• Avoid spaces and symbols

✅ Good Examples:

gas-config
my_custom_addon
weather_system

❌ Bad Examples:

Gas-Config        ← uppercase breaks it
Gas Config        ← spaces fail on Linux
Gas_Config!       ← exclamation or symbols aren’t allowed

🔧 How to Fix Addon Names

1. Connect via SFTP or use the File Manager.
2. Navigate to:

garrysmod/addons/

3. Rename folders to follow the rules.
4. Restart your server.

Tip: Even if you upload from Windows, always double-check the folder names in /addons/ after extraction!

✅ Why It Matters

• Linux treats Gas-Config, gas-config, and gas_config as completely different.
• Stick to lowercase + hyphens/underscores to avoid missing addons.
