Hi!

On my laptop, a Lenovo T490 I have observed that two function keys map to an identical notify code, this makes it hard to separately map to actions with a notify match script. The keys in question are located on F5 (brightness up), and F12 (favorites).

[/usr/local/sbin]$ cat /var/run/devd.pipe
**press brightness down (F5)**
!system=ACPI subsystem=Video type=brightness notify=14
!system=ACPI subsystem=IBM type=\_SB_.PCI0.LPCB.EC__.HKEY notify=0x11
**press favorites key (F12)**
!system=ACPI subsystem=IBM type=\_SB_.PCI0.LPCB.EC__.HKEY notify=0x11
**press brighntess down (F5)**
!system=ACPI subsystem=Video type=brightness notify=13
!system=ACPI subsystem=IBM type=\_SB_.PCI0.LPCB.EC__.HKEY notify=0x11
**press favorites key (F12)**
!system=ACPI subsystem=IBM type=\_SB_.PCI0.LPCB.EC__.HKEY notify=0x11


is there any way that I can distinguish on the key presses to map to different actions?

Are you using acpi_ibm module?

If you are in Xorg, some key presses might appear in xev (e.g. as XF86AudioLowerVolume). In that case hotkeys can be handled by the window manager as well.
