Boinc not recognizing OpenCL version

(moderation:
Latest Ubuntu, (20.04.2) and Nvidia Driver, (460.39), GTX 650 ti Boost and yet Boinc will not recognize OpenCL so E&H is not sending any work. In Boinc messages, it shows the GPU and CUDA version but no OpenCl version. I have another older PC with the same setup and it shows an OpenCL version and is doing work.
Is there something I'm missing?

This isn't E@H related but you need OpenCL. I haven't used 20.4 but NV driver has just come with CUDA.
sudo apt install ocl-icd-libopencl1
Under Debian you'd have to

Under Debian you'd have to install the nvidia-opencl-icd package. Reboot and check BOINC startup messages. There should be an OpenCL line in the BOINC log after the line mentioning CUDA.
If it really is a GTX 650 Ti then it was released in 2012 and is rather old in GPU terms. You might find the current drivers don't support it and you would need the legacy drivers.
[edit]Checking the Ubuntu website and it seem they have an nvidia-opencl-icd-384 package. The number on the end seems to relate to the driver version. It looks like 384 supports the 384 and 390 driver.

There is a known problem with installing AMD (OPENCL drivers) on Ubuntu 20.04.2. You can read more about it here. (scroll down near the bottom) You could try a different distro, i.e., Fedora, .... I have not tried a different distro so I can't speak to the success of installing AMD drivers on different distros.
