[Bug 1448485] Re: [Compaq Presario CQ60-300EO Notebook PC] kernel doesn't recognize backlight fn keys

 

Cool I'm also using mate 16.04 ;D pity you don't have the
/sys/class/backligt/acpi_video0(sure you don't have it? using standard
ubuntu kernel?) I made tow scripts that can lower and higher the
brightness but they depends on acpi_video0 directory. I'm learning to
program in c end linux kernel programing to get that hp_wmi driver to
read the key code or whatever rigt, and there is a problem with the
blue-light wifi button. the get the wifi up going after that is a pain
in the as. most reboot the computer and run:

[code/]run ip ip link set wlp7s0 up
rfkill unblock all[/code]
sometimes it works somtimes not just reboot and try again..

I like to get all the keys to function, and I'm gonna do it my self. wmi
driver is old and not so functional except for the volume and play and
paus still work with is grate, there are approximately 8 key that are
not working or is kind of buggy working, like one key that worked
sometimes but sometimes not

Title:
  [Compaq Presario CQ60-300EO Notebook PC] kernel doesn't recognize
  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
