Setting the option "invert_brightness=1" solved the > problem. Hi Bernd - The i915.invert_brightness parameter has only ever been needed on some gen4 Acer laptops; I suspect this is something else. Please drop that parameter, and try one of the v3.13-rc kernels or video.use_bios_initial_backlight=0 module parameter. If those don't help, please file a bug on Product=DRI, Component=DRM/Intel as instructed in [1]. BR, Jani.
