Hi all.
Three years ago I had a lot of help (for which I’m forever glad) from this forum to make my notebook’ discreet gpu card work properly: it was the " nVidia + Cuda + Bumblebee + Codecs: “Recipe” not working on openSUSE 15.2" topic.
It worked nicely since then (even leading to the introduction of GPU usage at my workplace, however there are no “optimus and likes” issues), but unfortunately 2 weeks ago the HD from that notebook failed.
15.2 days have already passed, so I’m now using the latest version of openSUSE. However, as mentioned in the " Cuda + Nvidia + bumblebee + codecs “safe” way" topic, the path for bumblebee became way too rocky.
As such, I tried the most simple thing to have cuda working: installed the opensuse 15.5 with nomodeset enabled, disabled the nvidia drivers repository and included the official cuda repository for just then install both cuda and the drivers from there, removed nomodeset and finally rebooted.
Unfortunately, it didn’t work, and I’m needing help to make it work. 
Here follows some commands outputs to better show what is happening:

~> ./deviceQuery
./deviceQuery Starting...
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 100
-> no CUDA-capable device is detected
Result = FAIL
Also, there are no /proc/driver/nvidia/version and /dev/nvi* files…
Does anybody have any idea on how to solve this? Thanks a lot in advance!
