  • Auto-launching GMod after patching
  • Fixing Steam Overlay/MangoHud/etc

Auto-launching GMod after patching

ℹ This enables you to configure GModPatchTool to launch GMod immediately after successfully patching.

Create a Bash script named RunGModPatchTool.sh in the same folder as the gmodpatchtool executable, containing the following:

#!/bin/bash ./gmodpatchtool --launch-gmod --skip-exit-prompt

Mark your script as executable using its File Properties or by using the chmod +x command in Terminal. You should now be able to simply double click the script to patch GMod and then run it without prompting you on close.

Fixing Steam Overlay/MangoHud/etc

Go to Steam > Garry's Mod > Properties > General > Launch Options. In the Launch Options text box, enter the following before any other launch options:

GMOD_ENABLE_LD_PRELOAD=1 %command% GMOD_ENABLE_LD_PRELOAD=1 enabled in Garry's Mod Launch Options

Should Garry's Mod crash with this option set, simply remove GMOD_ENABLE_LD_PRELOAD=1 %command% to return to normal.
