GPU slots disabled on Debian 12

[cduchat]

Hi Fabio,

I am having GPU detection issues on Debian 12 Bookworm and current gen hardware (Ryzen 7950X and an RTX 4070ti).

More precisely F@H created and disabled slots on both the iGPU and the main GPU (the slot CPU is properly created and active).

In the "System Info" tab I get:
"CUDA Not detected: Failed to open dynamic library 'libcuda.so': libcuda.so: cannot open shared object file: No such file or directory" and "OpenCL Not detected: clGetPlatformIDs() returned -1001"

The NVIDIA drivers are correctly installed and include libcuda.so (along with several links of the same name pointing to it from various locations throughout the system).

At the first install of the SNAP package I had not seen the command for proper GPU detection so I got the issue. That's when I found the command and ran it but it did not correct anything, so I also "refreshed" the SNAP but the problem remained. I then uninstalled the SNAP, deleted the entire /Home/snap/folding-at-home-fcole90 folder, reinstalled and immediately re-ran the command for GPU detection, but I still have the issue.

Any idea of how to get CUDA detected and the main GPU to fold? Was there another folder I should have deleted to fully remove the F@H config when I uninstalled? Do I need to create a "libcuda.so" link anywhere to point to the location of the CUDA install?

Thanks,
Christophe

Quick update to say I used your reply to the issue "The fah snap doesn't use config.xml? Where do I edit config?" to deactivate the deamon and created a bash script to start instead in the userspace.
No change in behavior: CPU slot runs, GPU slots disabled because neither CUDA nor OpenCL are detected.
