T128 thrustmaster on SteamDeck

[saix0017]

Hi everyone, since I have a t128 thrustmaster it doesn't work. So where do I start? Can someone help me with the procedure? Do I have to go to the Linux console and emit codes? If so, give me the code and I'll try, thanks for anyone who can help me.

Hello, looks like this might be your first time interacting with an open-source project. I'll try and help you out, but your request doesn't quite contain enough information for me to give any useful advice at the moment. Generally, you should always include

1. What you did. In this case, you presumably followed the README's instructions, but it's better to be explicit rather than assume everyone knows what you did. If you ran some commands, show them, preferably in a code block. You can create them with three backticks, like so: ``` some_commands ``` (try not to use screenshots). If you're asking for help on how/where to run the commands, that's fine as well, installing this driver is sometimes the first time a new Linux user has to open up a terminal. I'd be happy to go into more detail if that's what you're having trouble with.

2. What went wrong. Did one of the commands fail, and if it did, what was the error message? Show the error message, either in the same code block as mentioned above or separately, but make it clear which command the error came from. Preferably show the error message in English, but if your system is in some other language and you don't know how to change it temporarily, don't worry about it too much. Usually error messages are guessable from the context.

3. What did you try to solve it. Sometimes there are solutions on StackOverflow for related issues that people try before asking for help directly, and they're often the first things a maintainer asks you to try as well. If they didn't work, please also include what went wrong (I guess you can think of this as repeating points 1 and 2).

It's usually also a good idea to mention which operating system you're using and what version. The more information you show, the better. Unnecessary information never hurts to have (except personal/private information) but having too little information means the maintainer (or whoever is trying to help you out) has to ask for the missing stuff explicitly, which means that your problem takes longer to solve. If you're unsure what information might be useful, it's of course fine to just ask as well.

I repeat again with this distribution that I have arcs linux how do I download dkms?

[Kimplul]

I don't have a Steam Deck, but I believe it should be something like the following:

sudo steamos-readonly disable
sudo pacman-key --init               # only required the first time you install software, iuc
sudo pacman-key --populate archlinux # ditto
sudo pacman-key --populate holo      # maybe required for newer systems?
sudo pacman -S dkms
sudo steamos-readonly enable

[saix0017]

ok i just finished entering the commands you sent me now i have the dkms?

[saix0017]

[saix0017]

what should i do? is t128 installed?

[Kimplul]

ok i just finished entering the commands you sent me now i have the dkms?

Assuming all the commands succeeded, then yes.

what should i do?

Now that DKMS is installed, you should run commands in the README again. Please do report back any errors, you might get one due to the immutable filesystem on the Steam Deck, but I'm not quite sure.

Not quite sure what happened to your picture but it's not showing, it's just a hyperlink to this discussion.

[Kimplul]

Oh whoops, mean this as a reply instead of a new comment. Oh well.

[saix0017]

I made you an image below what should I do now?

[saix0017]

[saix0017]

now what do i have to do does it have to go now?

Trustmaster steering wheel doesn't work t128

[Kimplul]

Try

sudo steamos-readonly disable
sudo pacman -S linux-neptune-65-headers
sudo steamos-readonly enable

It looks like you previously tried to install linux-neptune-61-headers, which is for the Linux 6.1 kernel, but you're running 6.5, as mentioned in the DKMS error message.

[Kimplul]

To be clear, SteamOS, which is the 'distribution' that runs on the Steam Deck, has an immutable filesystem. It (roughly) means you can't do modifications to your system unless you run sudo steamos-readonly disable first. Any error message about read-only system or permissions will (probably) be fixed by the aforementioned command.

[saix0017]

stay connected I'll try again

[saix0017]

hello happy holidays again if you're there can you give me a hand?

[saix0017]

good morning on motorist 2 the steering wheel works even with ffb but the rev counter LED doesn't work do you know how to do it?

[saix0017]

Automobilista 2*

[Kimplul]

I'll explain then I tried again on race room the steering wheel turns all the way to the right with force then disappears after 30 seconds it turns missing force, euro truck 0 force it turns a bit of a dead zone but there is vibration

Sorry, I'm having a hard time understanding what you mean. ETS2 vibrates but you say 0 force? Vibration is a force when talking about FFB, if you mean that there should be some kind of autocentering or something, that's a slightly separate issue. Have you looked at Oversteer, it should allow you to set the autocentering and some other things.

good morning on motorist 2 the steering wheel works even with ffb but the rev counter LED doesn't work do you know how to do it?

Unfortunately, no. I don't think any LEDs on any wheels supported by this driver work at the moment, it's a known limitation. Mainly just because I nor anyone else has looked into how the Windows driver talks with the LEDs.

[saix0017]

update I tried again on ets 2 solved because I had set joystick mode with steering wheel it's perfect. regarding raceroom I have to understand on the game I had inverted the force from the game I felt but the steering wheel turns every now and then by itself. regarding led I understood I hope you program in the future

Looks like the kernel version matches, and I guess the compilation would've failed if that was the issue, interesting. Did you already reboot, by the way?

[saix0017]

yes I restarted steam deck and it doesn't recognize steering wheel, too bad I think steering wheel won't work anymore then

[Kimplul]

I doubt they're completely unusable, but I don't have a deck myself so unfortunately you're going to have to either wait for someone to pop in and check if they can replicate or see if you can get the wheel to work on a friend's deck or something. Sorry :(

[saix0017]

don't worry update, everything is ruined, I'll switch to Windows and do it sooner
