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) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1665530 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. --- ApportVersion: 2.20.1-0ubuntu2.5 Architecture: amd64 CurrentDesktop: Unity DistroRelease: Ubuntu 16.04 InstallationDate: Installed on 2016-12-14 (65 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) NonfreeKernelModules: nvidia_uvm nvidia_drm nvidia_modeset nvidia Package: linux (not installed) Tags: xenial Uname: Linux 4.8.0-040800-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1665530/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
