By chance I have come today over these two pieces of information: * https://www.ddcutil.com/faq/ * which links to: https://lists.freedesktop.org/archives/intel-gfx/2017-May/127426.html
I don't use ddcutil, but I do have the i915 kernel module, which appears to be at fault. -quintus -- Dipl.-Jur. M. Gülker | https://mg.guelker.eu | PGP: Siehe Webseite Unna, Deutschland | kont...@guelker.eu | O<
