Help with Remapping Key 49 on German Keyboard Layout

[Martin Ivanov]

Hello, Peter,
thank you very much for your reply.
I did what you suggested and here is the output:

root at dragonfly:/home/marto # libinput debug-events
-event0   DEVICE_ADDED            System keyboard multiplexer       seat0
default group1  cap:k
-event1   DEVICE_ADDED            System mouse                      seat0
default group2  cap:p left scroll-nat scroll-button
-event2   DEVICE_ADDED            vendor 0x28a0 USB OPTICAL MOUSE, class
0/0, rev 1.10/1.00, addr 1 seat0 default group3  cap:p left scroll-nat
scroll-button

As you see, although I am pressing the key between the left shift and the
"y" letter on the german keyboard, nothing is detected. For a comparison,
here is the output when I press key 49:

root at dragonfly:/home/marto # libinput debug-events
-event0   DEVICE_ADDED            System keyboard multiplexer       seat0
default group1  cap:k
-event1   DEVICE_ADDED            System mouse                      seat0
default group2  cap:p left scroll-nat scroll-button
-event2   DEVICE_ADDED            vendor 0x28a0 USB OPTICAL MOUSE, class
0/0, rev 1.10/1.00, addr 1 seat0 default group3  cap:p left scroll-nat
scroll-button
-event0   KEYBOARD_KEY            +2.823s *** (-1) pressed
^ event0   KEYBOARD_KEY            +2.936s *** (-1) released

I remember that when I upgraded to dragonfly 6.4.0, the whole keyboard did
not work. Then, Pierre-Alain TORET (daftaupe) told me to set
kern.evdev.rcpt_mask=3.
I now have this added to /etc/sysctl.conf and my laptop keyboard
works, except for this key. Maybe this shall provide some clue to a
potential solution?

Best regards,
Martin
