Pro Controller, difficulty to activate Use motion (Linux)

[ghost]

Good morning,

I don't speak English, I translate with Google.

3 weeks ago I built Cemu on POP_OS 22.04 following this link: https://github.com/cemu-project/Cemu/blob/main/BUILD.md My Pro Controller worked including gyro movements. Unfortunately, I had to reinstall the whole system and now I no longer have access to the gyroscopic movements.

For information I tried several AppImage versions. I also tried to rebuild old releases (https://github.com/cemu-project/Cemu/releases/), but the build fails.

Another question. Currently do we still need to install programs like evdevhook, joycond-cemuhook… to be able to use gyro movements?

Thank you for your help and for your work.

Sorry again for my bad English!

I managed to activated the gyroscopic motion control!

I installed the package steam.

sudo apt install steam

It appears that one or more dependencies help Cemu enable gyroscopic motion control Maybe steam-devices ? https://packages.debian.org/fr/sid/steam-devices

Then in the POP_OS Bluetooth settings I removed my Pro Controller and activated it via the button next to the USB C port.

I launched Cemu-2.0-36-x86_64.AppImage.

In Cemu, options, Input settings. Emulated controller → Wii U GamePad

Controller, I deleted the old configuration by sectioning (-) and creating a new configuration (+) API → SDLController and Controller → Nintendo Switch Pro Controller, select Add

Then I click Settings and check Use motion.

With this method there is no need for program like evdevhook, joycond-cemuhook…

Long live Cemu!

I've figured out that it's game-devices-udev (https://codeberg.org/fabiscafe/game-devices-udev)

Thank you for the note

SDL2.28.5 (used in CEMU 2.0-65) does not support reading event# separated IMU inputs.

HIDRAW based motion works but you need to be able to read that as regular user. Steam installs udev rules for many controllers (including switch pro controller) so that regular user can read them. See https://github.com/cemu-project/Cemu/issues/1097#issuecomment-1952626670 for a dump of that file, you can place it in /lib/udev/rules.d/ and restart and HIDRAW for those controllers will be able to be read by any standard user.
