I don't know how to answer ... I think I followed your guidance ... I turned on
the laptop, logged in, opened the konsole, did the recommended installations.
In the /etc/x11/xorg.conf.d directory, the 'libinput' folder did not appear, as
I showed in the print, and the laptop keyboard worked.
Then I did the manual installation of xf86-input-libinput by konsole:
sudo zypper in -f xf86-input-libinput
When I restarted the laptop I had no keyboard ... the libinput debug-events,
only had an output for the USB keyboard.
Then I performed the uninstallation by konsole, using a USB keyboard:
sudo zypper rm xf86-input-libinput
When I restarted the laptop, I had the keyboard again, and showed the outputs
of libinput debug-events.
