Title:
kernel don't recognize laptop backlight fn keys
Status in linux package in Ubuntu:
Incomplete
Bug description:
I'm using Ubuntu 15.04 and fn+f7 and fn+f8 use to lower and higher the
brightness of the screen.
In slackware using kernel 3.14.33 those keys works and give output from
acpi_listen.
In kernel 3.16 to 4.0 those keys don't work and acpi_listen outputs nothing.
I expected fn+f7 and fn+f8 to work
