title: Getting Deus Ex GOTY Edition running on Linux

I've been struggling with this for a few hours, so I might as well document how
|
|
I did it.
|
|
|
|
I have a particular setup, which ended up causing issues. Most important are
|
|
that I'm using Sway, a tiling Wayland compositor, and a flatpak install of
|
|
Steam.
|
|
|
|
## Mouse doesn't move when the game is launched
|
|
It looks like there's a problem with the game window grabbing the cursor on my
|
|
setup, so moving the mouse doesn't move the cursor in the game and if you move
|
|
it too much to the side it takes you out of the game window.
|
|
|
|
The solution to this is using Gamescope, which is a nested Wayland compositor
|
|
that makes the window inside it play nice with your actual compositor.
|
|
|
|
Because I'm using the flatpak install of Steam, I needed to install the
|
|
[flatpak version of gamescope](https://github.com/flathub/com.valvesoftware.Steam.Utility.gamescope).
|
|
One catch here is that for me, this wouldn't work if I also had the flatpak MangoHud installed.
|
|
The only solution I could come up with right now was to uninstall MangoHud.
|
|
|
|
```bash
|
|
flatpak remove org.freedesktop.Platform.VulkanLayer.MangoHud # if you have it installed
|
|
flatpak install com.valvesoftware.Steam.Utility.gamescope
|
|
```
|
|
|
|
Then, right click on the game and select properties, then in launch options type
|
|
`gamescope -f -- %command%`. This will launch the game inside gamescope, and the
|
|
cursor should move inside the game now.
|
|
|
|
## The game is too dark to see anything
|
|
It looks like the game relied on some old DirectX or OpenGL features or
|
|
something, because once you do launch into the game, everything is extremely
|
|
dark and hard to see. At first I was wondering how anyone could play the game
|
|
like this, but it turns out that's not how the game is supposed to look!
|
|
|
|
I finally managed to solve this by following the installer steps for the
|
|
[Deus Ex CD on Lutris](https://lutris.net/games/install/948/view). Yeah,
|
|
roundabout way to solve it, but it worked.
|
|
|
|
First download the updated D3D9 and OpenGL renderers from the page, and extract
|
|
them into the `System` folder inside the game.
|
|
|
|
```bash
|
|
cd "$HOME/.var/app/com.valvesoftware.Steam/.steam/steam/steamapps/common/Deus Ex/System"
|
|
wget https://lutris.net/files/games/deus-ex/dxd3d9r13.zip
|
|
wget https://lutris.net/files/games/deus-ex/dxglr20.zip
|
|
unzip dxd3d9r13.zip
|
|
unzip dxglr20.zip
|
|
```
|
|
|
|
Next, download and install the `1112fm` patch.
|
|
|
|
```bash
|
|
cd "$HOME/.var/app/com.valvesoftware.Steam/.steam/steam/steamapps/common/Deus Ex/System"
|
|
wget https://lutris.net/files/games/deus-ex/DeusExMPPatch1112fm.exe
|
|
env WINEPREFIX="$HOME/.var/app/com.valvesoftware.Steam/.steam/steam/steamapps/compatdata/6910/pfx/" wine DeusExMPPatch1112fm.exe
|
|
```
|
|
|
|
Follow the steps of the installer. It should automatically find where the game
|
|
is installed. Once the install is done, launch the game, then head into the
|
|
settings and pick "Display Settings", then "Rendering Device". In the renderer
|
|
selection window, pick "Show all devices", and then select "Direct3D9 Support".
|
|
|
|
|
|
|
|
Launch back into the game, head into the display settings again, pick your
|
|
resolution, and restart the game. Then head into the display settings yet again,
|
|
this time change the color depth to 32 bit. Restart once more. Yes, you do have
|
|
to do them separately or the game doesn't save the color depth change for some
|
|
reason. Finally, you can start playing!
|
|
|
|
|
|
|
|
|
|
## Other small issues
|
|
|
|
Here are a few more issues you might hit during this whole process:
|
|
|
|
> My cursor moves too fast!
|
|
|
|
You need to turn down the cursor speed. My mouse has buttons to adjust the speed on the fly, so I use those to turn down the speed.
|
|
|
|
> After changing resolution, I can't move my cursor!
|
|
|
|
Use the keyboard shortcuts (arrow keys and enter) to exit the game. It should work again when you restart.
|
|
|
|
> The cursor doesn't move when I open the game, even with gamescope!
|
|
|
|
I'm not fully sure why or how this happens, but a few things I found useful:
|
|
|
|
- When the game is launching, and it's showing the animation of the studio logo, don't click! Press escape to bring up the menu instead.
|
|
- Press escape to bring the menu up, then hit escape again to dismiss it. It sometimes starts working after that.
|
|
- Use the keyboard to exit the game and restart. It always works the next time for me.
