Description Jaime Pérez 2014-06-10 21:13:00 UTC
All hotkeys of the laptop works but brightness ones. I have to change brightness level manually, but if I hit the key nothing happens. I suppose is a kernel issue. The fact that the minimun level of brightness is zero is a driver issue, I think. I don't know if it is a configuration problem or a bug. I will report all needed info.

please attach the acpidump output and the output of "grep . /sys/class/backlight/*/*".
BTW, how do you change the brightness level manually?
