+
+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.
