You can use the GUI app "keyboard shortcuts" to setup custom keys, or you can manually modify hwdb files (ex. /lib/udev/hwdb.d/60-keyboard.hwdb). The following tutorials may provide some help. == Modify keymap == * cd /lib/udev/hwdb.d/ * edit keymap file (60-keyboard.hwdb) * add a change, ex KEYBOARD_KEY_81=f20 # mic mute * run "sudo udevadm hwdb --update" * load changes "sudo udevadm trigger" (not tested) or reboot * not reboot required: * udevadm hwdb -u * udevadm control --reload * udevadm trigger --action=add --subsystem-match=input * check updated keymap * udevadm info /dev/input/event more information * http://askubuntu.com/questions/499252/my-custom-udev-hwdb-rule-doesnt-work * http://thinkpad-scripts.readthedocs.org/en/latest/guides/additional-keys.html -- 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/1891032 Title: Brightness key freeze screen Status in linux package in Ubuntu: Incomplete Bug description: When I press the KEY_BRIGHTNESSDOWN or KEY_BRIGHTNESSUP the screen freeze for a few seconds.

I can control the brightness (with step up or down) using these commands: gdbus call --session --dest org.gnome.SettingsDaemon.Power --object-path /org/gnome/SettingsDaemon/Power --method org.gnome.SettingsDaemon.Power.Screen.StepUp gdbus call --session --dest org.gnome.SettingsDaemon.Power --object-path /org/gnome/SettingsDaemon/Power --method org.gnome.SettingsDaemon.Power.Screen.StepDown I was thinking of a workaround that disables the current Fn key program and I create a script that triggers these commands when I press Fn key but I don't know how to disable the current trigger -- 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/1891032 Title: Brightness key freeze screen Status in linux package in Ubuntu: Incomplete Bug description: When I press the KEY_BRIGHTNESSDOWN or KEY_BRIGHTNESSUP the screen freeze for a few seconds.

[Kernel-packages] [Bug 1891032] Re: Brightness key freeze screen
These 3 cause screen freeze
1. sudo acpidbg -b "e EV5 1 0" ("2 0" for brightness down)
2. sudo acpidbg -b "e \_SB.PCI0.GFX0.BRT6 1 0" ("2 0" for brightness down)
3. sudo acpidbg -b "notify \_SB.PCI0.GFX0.LCD 0x86" (0x86 for brightness down)
And these 2 don't work (tee:
/sys/class/backlight/intel_backlight/brightness: Invalid argument)
4. echo 3 | sudo tee /sys/class/backlight/intel_backlight/brightness
5. echo 6 | sudo tee /sys/class/backlight/intel_backlight/brightness
I tried 4 and 5 with root (sudo su) and without the "sudo" and returned
the same error...
I will read this wiki about backlight, thank you

[Kernel-packages] [Bug 1891032] Re: Brightness key freeze screen
The flow of brightness hotkey is as follows key pressed -> ec triggers events -> bios/os performs a series of following functions -> ... -> ACPI EV5 -> ACPI BRT6 -> ACPI Notify LCD 0x86/0x87 -> ACPI VGA driver generates keycodes -> userspace write to /sys/class/backlight/intel_backlight/brightness It is possible to manually perform functions in ACPI EV5 and later. EV5 and later does not freeze screen, hardware and BIOS are likely to be blamed; otherwise, it is possible to further narrow down which parts break and identify the responsible drivers. -- 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/1891032 Title: Brightness key freeze screen Status in linux package in Ubuntu: Incomplete Bug description: When I press the KEY_BRIGHTNESSDOWN or KEY_BRIGHTNESSUP the screen freeze for a few seconds.
