Hello,
OBS is not recognizing my new Nvidia drivers after updating today (455.28-4 > 455.28-7) I've rebooted - no luck. I attempted to revert the driver back, however, my Xorg refuses the start when I do that. Nothing additional with Nvidia was updated other than the driver (no utils or settings).
I get the below error when attempting to record with OBS:
[h264_nvenc @ 0x5604fdea8c80] dl_fn->cuda_dl->cuInit(0) failed -> CUDA_ERROR_UNKNOWN: unknown error
warning: [NVENC encoder: 'simple_h264_recording'] Failed to open NVENC codec: Unknown error occurred
I'm not sure what my next step should be if I'm unable to revert the driver back.

Nothing? Not even the kernel? If not, you're doing things very wrong.

Yes the kernel did as well among others.
Sorry, I fixed the language to specifically speak to updates that would apply to Nvidia.

The kernel's the main issue here. It's been covered in other threads, and in plenty of linux news outlets.

Oh ok! Sorry for the post. I should have looked further.
Is it worth reverting the kernel back or is that a huge headache?

I have the same problem on 2 Arch Linux installations.

As mentioned in the news, anything other than pure graphics is currently broken in a nvidia/linux5.9 setup.
