I have installed Ubuntu-22.04-LTS on a Steam Deck half a year ago.I could read the joystick-input from the built-in joysticks of the Steam Deck without any problems.
However, since last week reading the joysticks does not work anymore.I usually read the joysticks with the python-libraries "pyjoystick", "pyglet", or "pygame".For troubleshooting, i also used the ubuntu-application jstest and jstest-gtk.The joystick is definitely still detected and shows the correct information:
- Steam Deck
- Device: /dev/input/js0
- Axes: 10
- Buttons: 24
I also tried these troubleshooting-steps from the kernel-documentation: joystick-doc
I even set up a clean environment with another Steam Deck that I had lying around.First, I installed Ubuntu-22.04-LTS -> did not work again.Afterwards, I tried Ubuntu-24.04-LTS -> did not work.
Does anyone know what causes this problem. Seems like a driver issue.In the original Steam-Deck-OS, the joysticks worked without any problems. (Steam-Deck-OS now uninstalled)
Driver-version according to jstest:
jstest /dev/input/js0Driver version is 2.1.0.Information about the apt joystick-package:
