I follow this document, but looks like "kernel not translating the ACPI event
to an input event".
"sudo /lib/udev/keymap -i input/event4" not shown any reaction to Fn+F4 and
Fn+F5 in my case.
Also I see the two other possible problems:
1. Fn+F3 (button for switch between laptop LCD and external monitor) generate
same scancode like "p" button.
2. PrtScr and Fn+PrtScr generate same scancode, but Fn+PrtScr must generate
SysRq scancode.
When I test I found the BIOS of this laptop have "key release" event
problem. Desktop sticks many times while testing. If it possible to fix
using BIOS update, what I can exactly request from this laptop
manufacturer for fixing in next BIOS update? I mean there is any
description of the problem in technical language?
** Changed in: udev (Ubuntu)
Status: Incomplete => New
** Description changed:
- Binary package hint: kubuntu-desktop
-
- I have a Lenovo Y550-4CWI laptop.
+ I have a Lenovo Y550 laptop.
Fn+F4 should open monitor settings, Fn+F5 should open wireless settings.
I test it using xev - no any reaction to this buttons.
