--- Comment #1 from Aaron Lu <[email protected]> ---
Do I understand correctly that without any backlight related kernel cmdline
options, on the v3.14 kernel, the backlight hotkey doesn't work under a GUI
environment?

If so, does manually echo some values to
/sys/class/backlight/acpi_video0/brightness work?
