Issues fixed[edit]

Black and purple textures and giant red models[edit]

See Missing models or textures.
Frequently featured contents come from just a bunch of other Source engine based games (Counter-Strike: Source, Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two).

Game crashes at title screen[edit]

Game crashes at the title screen, after the loading screen[citation needed]
Not a proper fix; Simply a work-around.
  1. Find Garry's Mod in your Steam Library
  2. Select Properties
  3. Select Set Launch Options...
  4. Enter +connect 1:1
  5. Press OK
When the game opens, it will take you to a Connecting to Server screen. After a few seconds it should dissappear and take you to the title screen. It will then freeze for a few seconds, then function normally.
Sometimes you may need to press Alt+Tab then go back into the game for this to work.

Hosting a listen server[edit]

Start listen server[citation needed]
To host a server while playing, one must be able to forward ports and enter a console command.
  1. Forward the ports 27015 and 27005
  2. Enter sv_lan 0 in the console
  3. Press "Play Multiplayer" and select a map
  4. Others should now be able to join


In order for your server to show up on the server list, you must change sv_region to a value corresponding to your region.

Could not load library client (Linux)[edit]

Additional Libraries[citation needed]
  • Install the appropiate lib32 gconf package (libgconf-2-4:i386 for debian-based systems, libgconf-2.i386 for rpm-based distros, and lib32-gconf on the AUR for arch users).

Game changes microphone gain at launch[edit]

It is annoying for pro users who use a fixed value for their microphone gain.
Generic fixes for this issue can be found on our Source engine page.
