Arch detecting one key as another from keyboard.

John Path · 2022-02-19 10:56:29

Hi friends,

My laptop is detecting a function key which is that use to project my screen on another monitor on windows (on F7 key) as Super_L.

I want to launch a script to extend the monitor when fn+F7 is pressed but it is also starting while i am pressing the actual Left Super Key.

This is the output of showkey while pressing and releasing fn+F7

keycode 125 press
keycode  25 press
keycode  25 release
keycode 125 release

This is the output of showkey while pressing and releasing the actual left super key

keycode 125 press
keycode 125 release

Output of xev -event keyboard while pressing fn+F7

Fn+7 fires Super_L+P (because that's the windows projection shortcut) and that's bound to something already (the keymap notify event indiactes that)
You're not gonna be able to reasonably change anything about that behavior, but it's not clear to me what your actual goal is here ("but it is also starting while i am pressing the actual Left Super Key")

I want to launch a script while pressing fn+F7 with sxhkd

Super_L
  ./project.sh

It works while i press fn+F7 but when i press the actual Left Super key (super key near to fn key)
it also runs the script.

So, i want to run script when window project key is pressed but not when super key is pressed

So bind the script to "Super_L + P"?

Binding script with "Super_L + P" is not working

"does not work" isn't a problem description.

Do you fail to bind the shortcut to anything, do you successfully bind it to the script but the script doesn't work or are there other problems?
The xev output tells me that it currently is bound to *something*.

Edit: or does binding Super_L+P actually work and triggers the desired action, but the hotkey does not yield the same behavior?
