From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

on my gaming PC, it never used the GPU.

In my experience, that is usually a problem with the GPU OpenCL drivers. Sadly, the Mesa OpenCL implementation didn't include image support when I last checked (you can check with clinfo | grep "Image support"). For AMD cards you need to have either the "pro" driver or ROCM installed, both aren't packaged by all distros. Similar with Intel, don't know about Nvidia, but I'm sure if it works, it's only with the proprietary driver.

I ended up installing darktable in an arch distrobox container, as arch has ROCM packages (in AUR) and ever since GPU acceleration is working fine.
