I'm using Debian Jessie with LXDE on a recent notepad. The command "showkey -s" prints "0xe0 0x4c 0xe0 0xcc" when Fn+F2 is pressed. But dmesg tells me:
atkbd serio0: Unknown key released (translated set 2, code 0xab on isa0060/serio0).
atkbd serio0: Use 'setkeycodes e02b <keycode>' to make it known.
Two questions:
1. Where the scancode e02b comes from?
2. Why the command setkeycodes e02b 44 works but not setkeycodes e04c 44?
I also noticed that when I press Fn+F2, "evtest" prints 'ab':
Event: time 1481025600.385595, type 4 (EV_MSC), code 4 (MSC_SCAN), value ab
Event: time 1481025600.385595, -------------- EV_SYN ------------value 1
Event: time 1481025600.394373, type 4 (EV_MSC), code 4 (MSC_SCAN), value ab
Event: time 1481025600.394373, -------------- EV_SYN ------------
The command
setkeycodes ab 44
works too. Can someone help me understanding what's wrong?
Thank you all.
EDIT:
Both Fn+F2 and Fn+F3 have the same scancode (0xab) for evtest and dmesg, but showkey prints two different scancodes:
0xe0 0x4c 0xe0 0xcc for Fn+F2
0xe0 0x54 0xe0 0xd4 for Fn+F3
I wonder where the scancode 0xab printed by evtest comes from.
