Hi Paul, @pjaitken, If you're still trying to figure out the DDC command sequences and the Phillips control software runs on your Mac, I may have a solution. Recently I...

Thank you for reporting the hang. There have been similar reports in the past, but never have been able to reproduce the problem.  Are you able to reproduce it?  If...

Jacob, Thank you for the detailed tests.  I will review what you've observed. One minor thing to point out is that you can run ddcutil as a non-root user.  From...

What your tests show is that the hang happens when running 2 instances of ddcutil in parallel (& at the end of command), not when running them sequentially.  Based on...

Looking at the interrogate output, nothing jumps out at me. However, I'll note that monitors often have modes such as movie or HDR in which certain features such as brightness...

Other than suggesting that you look for OSD modes, I'm afraid there's not much to be done. Even name brand monitors can have a DDC/CI interface that does not correspond...

The error message you're seeing reflects the fact that modules.builtin file listing modules compiled in the kernel was not found at the expected location. That i2c-dev was not found in...

The initial checks for driver i2c-dev have been revised. If module i2c-dev is not loaded and we can't tell if it is built into the kernel, a warning is issued...

Thank you for the detailed post. It will take me a bit of time to fully think through the considerations, but I do want to acknowledge your message. kmod_module_get_path() depends...

I've upload changes using libkmod to check if i2c-dev is builtin or is a module file. Note that the check for i2c-dev at the start of ddcutil execution was purely...
