I haven't found any guides to modding Inquisition on Linux and Steam Deck and even just finding the tools to mod it can be difficult, so
now that I know what I'm doing, I've created a guide. Fair warning, this is for the Steam version. I don't know if this works if you didn't get it from Steam. It may be the same, it might not. I don't know and I don't have the resources to test it. If it is, please let me know and I'll edit this!

In this guide I am only using the DAI Mod Manager. I have not been able to get Frosty working with Linux. Maybe someone a lot smarter than I am can figure out a way to get it working, but I'm not that person. So, no .fbmods, unfortunately. If I can figure out a way myself or find a guide elsewhere, I'll update this guide.


Assumptions in this guide:
You already have hidden files showing in your file manager.



Starting off, you gotta get the tools. Here's the link to the DAIdiscord where you can find the up-to-date manager [https://discord.gg/wzJG7Mq].Because we're using Linux, ignore the prerequisites, just get the manager file.

Once downloaded, put it somewhere easy to find. It doesn't much matter where, I put it in my Home/Games/DAI folder for simplicity.

Once you've extracted it, open Steam and add the .exe as anon-Steam game and force the use of a compatibility tool. I'm using Proton Experimental. It's the one that's been the most stable for getting it to work. Other versions may work as well, but Experimental has been the most reliable.

Now launch the .exe through Steam. It'll launch (slowly) and you can set it up just like it shows in the manual. It's simply choosing where the Dragon Age Inquisition.exe is and where the folder with your mods are.

If Inquisition is on your internal drive, it's My Computer/C: or in My Computer/D: if it's on a micro sd card. Everything after that'll be in the same order as normal on Linux (steam/steamapps/common/Dragon Age Inqusition).

BEFORE doing anything else, go to .steam/steamapps/compatdata andmake note of the newest folder in there. It'll most likely be a long number (a lot longer than any Steam games). In case the mod manager has a fit, it's important to know which folder it's using so you can
easily delete it.

EDIT: since I created this guide, Steam has (at least on the Deck)made it so simply removing a non-Steam game deletes the compatdata folder. This is no longer needed but I am keeping in the guide in case it’s not the same on non-Deck PCs.

Now you can mod Inquisition! You can add mods just like you would with Windows, just download and put the .daimod into your mods file
and merge.

And there you go! Now you can play with mods! Just make sure when you get a working load order, make sure to write it down, this mod
manager doesn't save it.




If you're using a Steam Deck, the on screen keyboard glitches and becomes unusable if you try to type something. So far I haven't found this to be a big issue, just annoying when it keeps flashing until you close the mod manager. I've never come across a need for the keyboard within the mod manager, just be aware if flashing lights are a problem.

The mod manager is very prone to deciding it won't launch. To fix this, remove the .exe as a non-Steam game and re-add it as a non-Steam game. You might have to do it a couple times, there's nothing I know of how to fix this besides clearing the compatdata folder and re-adding it to Steam. You can try other Proton versions too but Experimental has been the only one that has consistently worked for me.
