[SOLVED] How to fix "Couldn't open /dev/input/event" for StepMania?

LittleSandra · 2024-01-19 22:02:25

I have just installed StepMania, but when I start it I get the below errors.

It looks like the game pad is detected, but nothing happens when I press any of the buttons.

Does anyone know what the problem could be?

I am using Wayland+Sway.

getfacl /dev/input/event0

Interesting. So a udev rule have to be made for the gamepad?

[a@t470s ~]$ getfacl /dev/input/event0
getfacl: Removing leading '/' from absolute path names
# file: dev/input/event0
# owner: root
# group: input
user::rw-
group::rw-
other::---

the wiki wrote:

f your system does not already happen to have a udev rule for the device you want to use, you can either write one yourself or install the game-devices-udev AUR package and restart your computer.
Note: It is possible to add a user to the input group in order to give them access to all devices. However, this is not recommended [5].

Afaict 0079:0011 is not covered by the game-devices-udev AUR package, so you'll have to add a rule, yes.
You can look at https://codeberg.org/fabiscafe/game-devices-udev for a pattern and if it works, maybe share it w/ the project.

Ok, I can see I am not smart enough to figure the udev stuff out. So I did

yay -S game-devices-udev
sudo usermod -a -G input a
reboot

which seams to work

Thanks a lot
