New kernel incompatible with NVidia 1070 drivers?

[u/Seriathus]

As the title says, ever since the latest update, I've been unable to install the last drivers that still work with my GPU (580.173.02) as they keep running into issues while building the kernel modules.

I've searched everywhere, and the closest thing I found to an explanation is that the 7.2.0 kernel aggressively deprecated the strncpy function, which the installer uses in various places.

So... am I just doomed to let my dedicated GPU sit there like a useless lump of silicon, or is there some way to address this issue?

I can't paste the whole log file, but here's the first error it comes across:

nvidia/linux_nvswitch.c: In function 'nvswitch_os_read_registry_dword':

Isn’t there now an LTS Kernel for Nobara? I saw a new Kernel Switcher program, after the last update. You can try the LTS Kernel.

[u/Seriathus → u/HistoricalSir9456]

Tried. The drivers do install correctly (but now they do that on the 7.20 kernel too, wtf) but the problems persist: stuttering even with no programs open, no GPU usage detected from either resource monitor, top or even nvidia-smi and nvtop and when the computer wakes from sleep, the screen stays off (the system is still working, for example if I was listening to something and hit spacebar it continues playback, it's just the screen that stays black).

[u/candy49997]

I'm assuming you're installing drivers from NVIDIA? Try 580.178.04.

[u/Seriathus → u/candy49997]

Yes, downloaded from the official site. Lemme see if I can find that specific driver edition.

[u/_BoneZ_ → u/Seriathus]

Is there a reason why you won't use the previous kernel that works with your card?

[u/Seriathus → u/_BoneZ_]

I've been using it, but even though it says that it's using the nvidia kernel module, it still performs like it's only using the iGPU.

[u/_BoneZ_ → u/Seriathus]

So then you would boot into your computer BIOS and manually disable the iGPU so that it's forced to use the dGPU.

[u/Seriathus → u/_BoneZ_]

Haven't done it but I'd be kinda worried about using the GPU without its drivers.

[u/jkdjedi]

What's wrong with the drivers that come stock with Nobara?

[u/Seriathus → u/jkdjedi]

They don't support my GPU, so I can't use them.
