It doesn't work on Fedora28

[Nindainell]

When i try to write the log to a file (in a Fedora 28 workstation system) it captures the login and logout, but anything else. The command i used was: sudo logkeys -s -m es_ES.map -o ~/logkeys.txt
thx =D

Did you try/specify --device switch?

[rolfvreijdenberger]

go through all devices in /dev/input by using 'cat /dev/input/eventX' and try to type some stuff. when you see things appear in stdout, you found the correct device. (X is a nunber)
that device should be used as the device to monitor.
I'm using fedora and have no issues this way.
