Is this running the latest -HEAD? Yes, some extra code was glued into the i915kms / drm2 code from Linux that correctly selected the right video output device for the brightness controls. (the opcontrol patch that I committed a couple months back.) The buttons don't work on my X series laptop, but the sysctl does. the buttons work for others on other X series laptops. It's likely some more ACPI and i915kms things need porting. -a On 19 October 2014 07:34, Renato Aguiar <renato@aguiar.info> wrote: > Hi Lars, > > On my X230 I only can change brightness calling acpi directly using > acpi_call.
