I have a gigabyte P57X v6-CF3, with the latest bios installed. I can
confirm this bug is present in ubuntu 16.10 with kernel
4.10.1-041001-generic.
Fn keys which work:
-F1 (sleep)
-F7 (mute)
-F8 (lower volume)
-F9 (increase volume)
-down arrow (play/pause media)
-up arrow (stop media)
-left arrow (previous track)
-right arrow (next track)
Fn keys which don't work:
-Esc (not sure what this is, possibly open dvd drive)
-F2 (don't know)
-F3 (decrease screen brightness)
-F4 (increase screen brightness)
-F5 might not work (looks like change display => cannot test)
-F6 (lock trackpad)
-F10 (don't know)
-F11 (disable/ enable wifi and bluetooth)
-F12 (camera, but haven't properly tested because no cam software installed)
-Prt Scr (sysRq)
-Delete (insert)
-Num LK (Scr LK, so can't really test)
-space (screen brightness, but it seems impossible to configure the
keyboard brightness at all on ubuntu)

Title:
Brightness control keys not working on Gigabyte P57 laptop
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have a gigabyte P57 laptop running Ubuntu 16.04 kernel 4.8.x. My
brightness control keys (fn+F3, fn+F4) are not getting detected. After
reading about how keypresses are handled by the Linux kernel, I used
showkey to check the scancodes of these keys. I did not get any
output. Similarly no output from xev, evtest and acpi_listen.
Just for your reference, other keys like volume up (fn+F9) are working
alright.
