How can I modify kernel for function key in laptop?
Hello guys,
I'm looking for how can I add function key keycodes / scancodes. In linux, I can only use few of function keys of my laptop. So, I'm looking for methods to use other function keys. In 'xev', no scancodes represent for those function keys. Instead, when I typed those keys in 'acpi_listen', some of the keys work. In that case, I want to know what problem is. If the problem is related to kernel, what is part that I should modify? Thank you. |
What distro/version is the one in question?
A web search for "keymap [distro name]" might turn up useful information. |
I'm using Arch Linux.
Is scancode related to keymap? Then, what about fn key combination? I found information that it needs to use keyboard driver to use fn key properly. |
The keyboard driver translates the scancode received from the keyboard into a character or action. If you're talking about the Fn key, then that cannot be accessed by Linux. The particular combinations using it are handled by the keyboard circuitry, which outputs a scancode when it's appropriate. Either way, the kernel isn't involved.
What exactly are you having a problem with? |
Thank you very much, DavidMcCann.
Now I can understand why Linux kernel cannot suppport fn key of my laptop. |
