All sensors show "0"

I've built the project, had to add export CFLAGS=-fPIC or it would not link with libsensors. The result is:

The system is Fedora 39, running on an ASUS Rampage IV Formula motherboard.

sensors returns:

You should use the branch libcosmic, it contains a patch for it. However, last time i tried on Linux, i had some very weird panic (something related with ui rendering). Maybe its only the libcosmic branch, i'm curious about that.

The fact it shows 0 is actually normal, you have to select a behavior on the picklist of a control (the left column, where there is None).

But rn, you don't have any behaviors, you currently need to create them with a config file, you can copy past one of my test configs: https://github.com/wiiznokes/fan-control/tree/main/.config in ~/.config/fan-control/

don't forget to set the config name in the setting file.

When a sensor is not used in the config, e.i., his value will not impact the % of a control, his value is not updated. I plan to make a mode more optimized for the UI in the future.

Also, note that i don't think i currently implemented the code to set the value of a control on Linux, i think it will only print a message in the console.

All of this is now fixed on Master. Sensors now get updated every time

OK, I've rebuilt it and now it shows me a window without decorations and nothing is clickable. It also takes 2 minutes to start the executable (time since Running target/release/fan-control` is printed to the moment a window appears). I'm running a KDE Plasma 5 session on Wayland. The graphics is nVidia GTX1080 with nvidia drivers if that matters.

This is normal for now.

nothing is clickable

This is weird, I've just tested on Ubuntu 23.10 and it works as expected.

It also takes 2 minutes to start the executable (time since Running target/release/fan-control

Idem, it works as expected for me. I suspect it is because of lm-sensors. Have you tried to use sudo ?

Also, I've made a considerable amount of commit until now, maybe it already fix the problem.

If not, try to report some logs:

export RUST_LOG=debug
cargo run --release && sudo ./target/release/fan-control

[wiiznokes]

Can you check if the new flatpak version fix it for you ?

[pglizniewicz]

I won't have access to the machine I've previously tested for another two weeks, checked it briefly on my ThinkPad X13 G3 AMD laptop on Fedora 40 with KDE Plasma 6 and it works.
