Missing Nvidia gpu brightness control on wayland (Fedora 41, Gnome)

i followed the fedora guide to install nvidia drivers

Which one? There are a few guides! Documentation is not Fedoras strong point :frowning:

Further: Check out https://wiki.ubuntu.com/Kernel/Debugging/Backlight

In particular

Backlight control does not work and there are no entries in /sys/class/backlight.

Further down on the Ubuntu link - check out the section " Into the abyss: looking at the ACPI BIOS" and see if you can follow that.

well i basically used

sudo dnf install akmod-nvidia

and some other commands to sign the hardware and stuff, i really dont remember, have to dig the command history again. The thing that bothers me the most that it works in x11 but not on wayland.
I will look into the links you provided.
Thanks

Looks good.

Can you run

modinfo -F version nvidia

If all is good it should report your version number.

yea, here is the output, also sorry for the delay was really busy with stuff

> modinfo -F version nvidia
565.77
> modinfo -F version nvidia
565.77

So that means your Nvidia is installed properly and is most likely not the problem.

I hope someone else will contribute some knowledge or ideas for you as I do not have any other leads at this time.

Thanks again
