Same effect on my Samsung Ativ Book 7 (intel i7 intel/ati hybrid) neither radeon, nor fglrx is working. Kernels 3.13.0-37, 3.16.0-23/24 don't work. Everything worked unter Xubuntu 14.04 (under 14.04 acpi_backlight=vendor even turned on brightness sensor) Under 14.10 ONLY brightness sensor works and cannot be turned off. Brightnesse keys tell me they are working by notification bubbles but screen stays at 100%. xbacklight does not decrease brightess although it tells me it it running at 50% (screen still 100%)
