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.

Yes I was aware of the 26.04 disclaimer. Yet I tried my chance just in case it may work with an older package. But so far everything failed.

Oh and that nvidia-smi, I was writing it wrong all the time and it explains it all. Maybe I had success sooner but could not appreciate it because of me writing the wrong command I will erase, purge, clean everything as in this great tutorial again and try one more time without expectations and if nothing works I'll either have to reinstall 24.04 or wait for Nvidia and Kubuntu to upgrade it.
