Hi @BlackMage2

Thank you for the interest in this project. Unfortunately, I have no information about how to control the display brightness on the Reiner SCT CyberJack. I usually shove the device into a drawer or unplug it so it does not annoy me. As far as I know, there is no Linux software available for changing the settings. If there was, it probably would be a separate tool and not directly included in this project.

Kind Regards
Hermann

hoehermann commented 4 months ago

That would be nice to have. Where can I get that software?

BlackMage2 commented 4 months ago

Indeed, the software provided by the driver package for Windows (found here) offers a method for controlling the display brightness. Unfortunately, the source is not provided and no documentation exists (as far as I know). In case you do have access to documentation or reference implementation, feel free to share the information.

The official driver for Linux (found here) is open source, but does not include a method for controlling the display brightness (as far as I know – I only skimmed the code, did not look thoroughly). In case you can give me some pointers, I would like to look into it.
