OpenCL not available after 'suspend/resume' cycle. Is there an easy work around?

Yes, I notice that too but don’t have an explanation. Here is what darktable thinks it’s running:

Further, I am confused about the resources OpenCl needs: the manual says:

“The principle OpenCL function flow is like this:
darktable > libOpenCL.so > libnvidia-opencl.so.1 > kernel driver module(s) > GPU
• darktable dynamically loads libOpenCL.so – a system library that must be accessible to the system’s dynamic loader (ld.so).
• libOpenCL.so reads the vendor-specific information file (/etc/OpenCL/vendors/nvidia.icd) to find the library that contains the vendor-specific OpenCL implementation.”

But my system does not have the file libOpenCL.so and neither do the other two Linux PCs that I have (not running Mint). All three PCs run darktable and OpenCl (most of the time). So, is the manual wrong ?
