Hi,
My setup is as follows:
Blender 2.83 / Blender 2.82a
Linux kernel 5.5.15
nvidia-drivers-440.64 / nvidia-drivers-440.82
GeForce RTX 2060 SUPER
This setup (nvidia-driver 440.64) has worked before. Then I moved the whole system to an internal SSD, and reinstalled the kernel and the driver (with the same configuration).
Now Blender does not find the CUDA device.
I removed the file
$HOME/.config/blender/2.83/config/platform_support.txt and restart blender, so it will be recreated.
The contents of the newly created file is:
{NVIDIA Corporation/GeForce RTX 2060 SUPER/PCIe/SSE2/4.5.0 NVIDIA 440.64}=SUPPORTED
So from this point of view - no problem.
The user preferences states, that there was no compatible CUDA device found.
The console output shows:
CUDA cuInit: Unknown error
This happens with the stable blender version 2.82a as with the daily of yesterday and today.
I straced the blender start and didn’t find anything taht would ring a bell in my head.
I started blender as root to pinpoint any permission problems … root gets the same problems.
A helping hand would be very appreciated here since I have currently no idea, what the reason could be for this…
Thanks a lot in advance for any support! Stay healthy!
Cheers
