Blender does not detect gpu after suspend [SOLVED]

mattf · 2020-04-23 06:28:37

Not sure what exactly is going on here. Right after I reboot blender behaves properly and shows my gpu as a cuda device. After suspending and resuming if i reopen blender my gpu is no longer detected. Other applications, like glxinfo, vulkan info, or a vulkan game shows my gpu and still produce output. Nvtop still shows that Xorg is using the gpu and if i run blender with prime-run nvtop shows that it is using gpu memory. Here is the output or "prime-run blender --debug-gpu-force-workarounds" :

      
Read prefs: /home/matheus/.config/blender/2.82/config/userpref.blend

GPU: Bypassing workaround detection.

CUDA cuInit: Unknown error

Still my gpu doesnt show on the list for cycles there:

I would be happy with any workaround for this if possible since it seems to be a bug. I just tested the new ubuntu 20.04 with nvidia-440 proprietary drivers installed, just as my arch, and the gpu option isn't showing up not even after the first startup. This issue occurs with both blender from official arch repos and from the official blender website.

All the outputs bellow are from this after suspend state where blender does not show the gpu and im pretty sure not much might be different before:

Please don't embed oversized images directly: https://wiki.archlinux.org/index.php/Co … s_and_code

Reads weird. Something you can try, though there's no guarantee for success, is enabling the new suspension related nvidia services that should help with many suspension issues. http://us.download.nvidia.com/XFree86/L … ement.html Read the systemd section paying attention to the noted preconditions and the necessary kernel module option, and enable the noted service files (you don't need to copy them manually like shown in the end, you can just enable them).

These often also have an interplay with the computers firmware, so you might want to try a UEFI/BIOS update.

Seems more like its an issue with cuda. I launched the sheepit rendering farm and it returned:

Nvidia::getGpus cuInit failed (ret: 999)
If you are running Linux, this error is usually due to nvidia kernel module 'nvidia_uvm' not loaded.

Which doesnt make quite sense since:

I will try the new nvidia suspension services

Okay, after running:

    sudo systemctl enable nvidia-suspend.service

    sudo systemctl enable nvidia-hibernate.service

    sudo systemctl enable nvidia-resume.service

and creating the modprobe file like:

$ cat /etc/modprobe.d/nvidia.conf 
         
options nvidia NVreg_PreserveVideoMemoryAllocations=1
options nvidia NVreg_TemporaryFilePath=/run

I suspended and hibernated and the gpu still runs.
