GModCEFCodecFix-Linux applied. _x86_64 beta branch.
Takes a long time to load and stutters while playing.
Crashed occassionally. Would consistently crash on the native Linux build.
Keyboard is only every recognized as US-QWERTY. Running on Proton, any verison, does not load the main menu without GModCEFCodecFix-Linux and running on the beta build.
GModCEFCodecFix-Linux
Everything takes ages to load, even moreso than Windows.
No matter what my keyboard layout is, it only recognizes it as US-QWERTY
The native Linux build crashes too frequently to enjoy it. Proton doesn't work out of the box, as the main menu doesn't load. GModCEFCodecFix-Linux was necessary to use to fix the main menu issue. The game still refused to acknowledge that anything other than US-QWERTY exists.
Perfect local & online multiplayer
Runs a lot better than on Windows 10.
./gmodpatchtool --skip-exit-prompt && %command%
Switched to the x86-64 branch, because the workshop addons I use crash the game on the default branch. Downloaded GModPatchTool (the beta for the version written in Rust), because the x86-64 branch crashes on startup without it.
The community layout by Manifest Wyverns is for the default branch of Garry's Mod, but Steam Input keeps layouts between branches separate. I highly recommend using the layout by Manifest Wyverns, but doing so on the x86-64 branch requires manual intervention:
- On the default branch, download the Garry's Mod community layout by Manifest Wyverns.
- Switch to the x86-64 branch, and create a custom configuration.
- With your configuration selected, press the Layout Options button (gear button next to Edit Layout), then select Layout Details. Take note of the path in the URL, after the
autosave://schema. It might look like/home/deck/.local/share/Steam/steamapps/common/Steam Controller Configs/.../4000-x86-64/config/controller_neptune.vdf. - Check
/home/deck/.local/share/Steam/steamapps/workshop/content/241100/577166696/controller_configuration.vdf. This should correlate to Manifest Wyverns's controller configuration. Copy it to the path in step 3, overwriting the original
The font in menus appear to be different than on my computer, running EndeavourOS. I don't know which one is the "correct" one.
Switched to x86-64 branch, installed https://github.com/solsticegamestudios/GModCEFCodecFix
After applying the necessary steps the game launches, in fact more mods work on Linux than on Windows, however very few files are missing. For example an addon doesn't play audio, a map's skybox has the bottom half as black, a weapon is missing texture, you get the point. Either way I'd say 99% of stuff works and it's really fun
It works exactly like Windows -Hammer.
It's not really GMOD as much as my internet connection, it's good but some friends live alot farther away.
gamemoderun %command%
Worked great, was missing some fonts but that's the only issue. Installed them manually and it was perfect.
./gmodpatchtool --skip-exit-prompt && GAMEMODERUNEXEC=prime-run gamemoderun %command%
Added GModCEFCodecFix beta from July 23rd, 2025 to the game root. Set beta branch to x86-64.
With gmodpatchtool, the x86-64 branch will crash if LD_PRELOAD includes Steam's gameoverlayrenderer.so, so Steam Overlay can't be used with it for the time being. LD_PRELOAD is unset by gmodpatchtool by default. If you need to add something to LD_PRELOAD, set GMOD_ENABLE_LD_PRELOAD=1, but make sure to manually set LD_PRELOAD so that gameoverlayrenderer.so is not loaded.
The game runs significantly better on the x86-64 branch than on the default branch, but fails to function correctly without gmodpatchtool (aka GModCEFCodecFix).
Runs great
The fonts look different than they do on Windows, but it doesn't really matter.
Changed branch to x86-64-chromium and used https://github.com/solsticegamestudios/GModCEFCodecFix
gamemoderun %command%
would crash when loading into a map on native version, had to use proton
taking a screenshot with the camera tool froze the game, but that fixed itself by the next time i booted up the game
A versão 64-Bits nativa não funciona, se quiser utilizar a versão 64-Bits você vai precisar forçar o jogo a utilizar a versão do Windows via Proton.
gamemoderun %command%
Just the wine/proton scripts Lutris installs when you first launch Lutris.
The 64 bit beta is completely broken by default.
gamemoderun %command%
Use this script from Github to get it working. Alternatively, you can use the default branch and the legacy linux runtime compatibility option. Or just use Proton, which works well but the game doesn't play nice with Wayland yet.

Уж не знаю, что конкретно мне помогло (доп.параметры или патчи), но до этих всех действий игра жутко лагала (с тем же протоном, на нативе просто вылетала игра), пролаги на несколько секунд и низкий фпс. Решил прогуглить, поставил gmod-linux-patcher через скрипт и доп. параметры - все залетало. после сталкнулся с проблемой ввода русских символов, они отображались как ???. Помог параметр HOST_LC_ALL=ru_RU.UTF-8.
Works quite better than on Windows, although the initial loading times are quite tolerable.
The loading times are also better than on Fedora when ran through Proton, even the game itself performs better! The Native also works, but it's best to play with Proton anyway. Use the x86_64 branch and don't forget to install the GmodCEFCodecFix to fix the menu issues!
Switched to x86-64 - Chromium + 64-bit binaries build with GModCEFCodecFix installed.
Switched to x86-64 - Chromium + 64-bit binaries build.
Opening the "Legacy Server Browser" through the "Multiplayer Game" menu seems to crash the game entirely upon getting closed. It seems to also take away access from accessing the rest of the game, which is really odd. No other VGUI menus seem to do this. This is easily mitigated by using the new server browser, or using Steam's game servers window.
The Native Client with 64-bit+Chromium support is not great, servicable, but nowhere near the quality you'd get by playing with Proton or on a Windows device. The normal client should be fine, however, but no one should use that anymore, as a good chunk of Garry's Mods content will be blocked off because of that.
SDL_VIDEODRIVER=x11 gamemoderun %command%
I use GModCEFCodecFix (https://github.com/solsticegamestudios/GModCEFCodecFix/releases).
The laser pointer on the rocket launcher is surrounded by a small black box.
Occasional stuttering and some weird audio glitches, probably just my addons not working.
When playing peer-to-peer, the game will randomly freeze and crash, sometimes requiring me to force restart my PC in order for it to stop freaking out.
(none)
Sometimes slows down when spawning in models, npcs and weapons. It freezes for a second or two before it goes back to normal
Sometimes loading a model list that has over 100 models and moving around as it loads crashes the whole game, complaining that it's out of memory.
If you love messing around and sandbox games, this certainly is a great game to try.
Native build crashed at startup, used this fix to make it work
Native build crashes everytime on loading screen, managed to make it work using this:
- Running the x86-64 branch of the game
- And doing this fix https://github.com/solsticegamestudios/GModCEFCodecFix
Works almost completely the same as Windows when running in Hotfix and using GModCEFCodecFix.
Certain Steam Workshop add-ons can cause the game to crash due to the differences between locating files on Linux and Windows.
Didn't try to use Proton because I wanted to use the native version. I made the following steps to make the game more stable:
- Enable the x86-64 Beta in the properties of the game.
- Install the following fix: https://github.com/solsticegamestudios/GModCEFCodecFix
- Enable Steam Linux Runtime 1.0 in the Compatibility section of the game's properties. (I don't know if this step is 100% required).
On proton hotfix without GModCEFCodecFix your keyboard won't send any input.
On steam linux runtime 1.0, after tinkering with GModCEFCodecFix the game runs perfectly fine. But on proton(probably without the tinker) you won't have any input from your keyboard reaching the game, and your console font will be bugged.
If you'll be using too many addons(~300) - your game and Linux GUI might crash.
When you make a long session the game can start have little lags just restart the game and it will be gone
The game does not open
A respective error regarding the compatibility tools occurs.
game works without any problems, native version crashes at initializing game data, windows version works without any problems

Game Crashes on startup. Switch to the Chromium branch and install this fix (link above).
fonts are broken on native, with them only being different on proton
It also works in Native, but those who live in a multibyte character area may prefer to use Proton.
At least in my environment, it worked in Native, so people in single-byte character sphere do not need to force it to work in Proton if it works properly in Native.
Change to x86-64 branch. Install GModCEFCodecFix.
With the native version, it would crash on the initial loading scrren with my system. I needed to change to the x86-64 branch and install the GModCEFCodecFix patch to be able to get to the main menu and start the game.
I also tried the game using Proton and that worked straight away. So that's another option.
Text is kinda small on the item spawnlist
Sometimes, garry's mod will freeze completely, and become a top-most application, so the steam menu wouldn't show up, and would need a whole console restart
Everything on high, antialiasing and motion blur disabled cause i dont like them, it runs at ~75 fps constantly, with some drops to 60, and sometimes reaching 90fps (which i limited it to). If too many entities or objects are displayed at once, it may even drop to 35 sometimes, but its mostly playable
Without any battery optimizations, and with some mods (not performance), it hovers around 12.5w, although you could drop that down to ~9w by enabling TDP limit (6w) and half rate shading, getting you ~6 hours of playtime (if not more. Steam is reporting 03:58 at 64%)
I haven't tried multiplayer yet, but singleplayer works fine out of the box
DRI_PRIME=1 %command% -freq 144 +fps_max 144 -nojoy -nosteamcontroller -vulkan
Used the following fix for the Native version: https://github.com/wayzaction/gmod-linux-fix
Some texture glitches, weird skyboxes on certain maps, fonts render differently and unicode characters missing. Also, the flashlight doesn't illuminate the props, but some of them can be illuminated and ragdolls are visible when used the flashlight on them.
Raw input can't be turned off and some server functions behave differently. Also, there is surely minor differences with how the engine recognizes the mouse position.
It is recommended to use the x86_64 branch and gmod-linux-fix for improving the performance on the Native Linux build.
Do NOT use Proton, since it has slower map loading times when Native loads them instantly. Although if you want to use the mods that go beyond LUA and use DLL files, then you have to use the Proton version, but be prepared for the different loading times than Native.
Overall, the game is pretty playable on Native, and I did not encounter any serious issues other than some minor artifacts that do not affect my experience!
Worked for me as long as I swapped over to Proton
Playing natively I was crashing about 5-6 times per session, my friends and I play with a decent amount of mods, around 300-400, so that could definitely be the cause for the crashing.
However, it seems like the Windows verion run through proton fairs much better, and after swapping over I haven't experienced a single crash.

Loading map slower than native windows but its tolerable
Get some patience at map loading and install CEFCodecFix
