Hi,
I am using GTX 1650, on Ubuntu 20.04. But transcoding is not working, I am getting this error "[AVHWDeviceContext @ 0x55d079661c00] cu->cuInit(0) failed -> CUDA_ERROR_UNKNOWN: unknown error" I already tired patching already from https://github.com/keylase/nvidia-patch.
Thanks

The Nvidia driver is incompatible with kernel version.

@nyanmisaka what would be your recommendation to fix this? Do I need to go the lower ubuntu version or driver version?
@manjotsc commented on GitHub (Feb 5, 2021):
@nyanmisaka I downgraded driver to 455.45.01 but still it's not working .
@nyanmisaka commented on GitHub (Feb 5, 2021):
What's your kernel version?

I don't have much experience about using Proxmox, maybe you need extra setup like in this thread?

@manjotsc commented on GitHub (Feb 6, 2021):
@nyanmisaka I have already done that part. Thanks

@nyanmisaka Solved the issue, nvidia-uvm-tools and nvidia-uvm were not loaded under /dev/nvidia*. Need to add nvidia-uvm under /etc/modules-load.d/modules.conf and run update-initramfs -u on host and rebooted and passed to lxc worked fine. I followed this guide https://bradford.la/2016/GPU-FFMPEG-in-LXC/#pass-gpu-to-lxc-container just until the step of installation Nvidia driver on container.
