I don't think Nvidia video drivers are broken, as I mentioned ,you need to run nvidia-settings with sudo privileges for all the settings and features.
I think we are going into the weeds unnecessarily, apologies for dragging things down there.
I have no experience with Cuda, that itself could well be broken, if the installation method you used specifically for Cuda does not yet support this very new kernel, and *buntu still being in a pre-release state.
So, what does it show now?
We really need someone with Nvidia experience here. I don't know where to go or what to ask, in terms of data gathering.

Good to hear I can't damage my Nvidia card, some people mentioned such things so it ringed possible lol. About Cuda I had installed Cuda in the working installation but took it away in the new kernel now. I will install it although now I tried to do a good form installation and failed again based on this page: https://linuxcapable.com/install-nvi...-ubuntu-linux/

nvidia -smi now says "command not found" again

I guess this new kernel is still not ready to receive some Nvidia cards since also Nvidia only support up to Ubuntu 24.04 if I remember correctly, so it's about being patient or go back to Kubuntu 24.04. Maybe installing Cuda may help and miracles often happen to me but thanks for all the support. I learned a lot from you. There's a spritual aspect in the way people connect in the web. You interact with someone you don't know but the ego is not so important, it's like a big plasma of collective open source identity with many eyes and ears that moves in waves.

But read the full page mentioning 26.04 and cuda. It is accurate.

nvidia -smi now says "command not found" again

nvidia -sm- or nvidia-smi (no space)? The latter is the correct command.
