Nvidia Enabled but not in use

Im new to fedora. would be very grateful if u help me resolve this and help me get familiar with fedora. Thank You

So be default, i had noveau in use. Since i wanted nvidia to reduce some load on cpu, i installed nvidia driver from rpm fusion(followed their instruction for installation too). Note that my system is optimus laptop, so i got intel+gtx.

After installing nvidia, nvidia-smi commands working, but the Settings show Mesa Intel® UHD Graphics and also there is no process listed in nvidia gpu.

Please do let know what more information is needed. Im still a newbie, so just gave more context and less debugging information(some is listed below).

Fedora 39
KDE
Wayland(X11 present too, but i dont use it)

On second thought added some outputs:

Removed audio

At some point it seems that something you have done has removed the nvidia-gpu-firmware package, which is required for nvidia GPUs.
Please run sudo dnf reinstall linux-firmware to reinstall the nvidia firmware package, then reboot so the device is properly supported.

Note that if you are using wayland it appears the only time the nvidia gpu is used would be when the user chooses to right click on the icon before launching an app and then selects to launch using the discrete gpu.

If you wish to use x11 then you can follow the instructions here and set the nvidia gpu to be primary after which it would be used full time.

So folliwing that link, X11 uses nvidia now.

But wayland isnt showing any option to use “nvidia” when i tried to watch a video. moreover it said codec is not supported :

VLC could not decode the format "hevc" (MPEG-H Part2/HEVC (H.265))
VLC could not decode the format "eac3" (A/52 B Audio (aka E-AC3))

The codecs are a different issue and not GPU related.
The simplest way I know to enable (almost) all the available codecs is to run
sudo dnf install ffmpeg libavcodec-freeworld --allowerasing. Once done try using vlc again.

References for multimedia use on fedora are here.

Note that you may or may not need the part about hardware accelerated from rpmfusion. I suggest you simply do not install any extra until you test with the command I already provided, then only install what is absolutely necessary and do not just install everything in that reference page.

got it.

The nvidia is also being used when needed in wayland. Thank you
