Hi,
I found a workaround to this problem. I solved the problem by installing new
packages:
"sudo apt install linux-modules-nvidia-390-5.15.0-56-generic"
where:
- "390" is the main version of the Nvidia driver (390.157);
- "5.15.0-56-generic" is the name of the kernel ("uname -r" output).
This induced the installation of the following packages: “linux-modules-
nvidia-390-5.15.0-56-generic”, “linux-objects-
nvidia-390-5.15.0-56-generic”, “linux-signatures-
nvidia-390-5.15.0-56-generic”.
LibreOffice now detects OpenCL; and clinfo output with 5.15.0-56 kernel shows
GTX 560 M is detected as an OpenCL platform:

Title:
Nvidia GeForce GTX 560 M not recognized as an OpenCL platform with
5.15.0-50 kernel
Status in linux-hwe-5.15 package in Ubuntu:

Bug description:
Hi,
Before to update to Linux Mint 21, based on Ubuntu 22.04 LTS, I have
tried 5.15.0-50 kernel with HWE. This was intended as a test of my
hardware compatibility with the hardware stack of Ubuntu 22.04, before
a possible update.
At a first glance, all seemed OK; nut I noticed that LibreOffice was
unable to use OpenCL. A simple "clinfo" command confirmed this:
$ clinfo
Number of platforms 0
I went back from 5.15.0-50 kernel to 5.4.0-128 one. Now, "clinfo"
output is:
$ clinfo
