Description of problem: Using function keys, Gnome control nor putting arbitrary values into /sys/class/backlight/acpi_video*/brightness will not change LCD backlight brightness. This is the same symptom as 891148 but refiling for Version-Release number of selected component (if applicable): kernel-devel-3.9.9-302.fc19.x86_64 How reproducible: Steps to Reproduce: 1. Install Fedora 19 on Dell E6530 2. Try to adjust LCD brightness Actual results: No change. Expected results: Dimming/intensifying of the LCD backlight brightness.
