Empty log file - and cannot find the 'event' in order to set the device.

[bikkaman]

I have installed logkeys and it seems to work but my logfiles are empty. I successfully used logkeys on my home Ubuntu 22.04 machine. Now I am trying (and failing) using a VPS with Ubuntu 22.04.

I run sudo logkeys -s -o file.txt -m /keymaps/en_GB.map

This results in a file but no logs.

Logging started ...
2024-09-07 21:55:17+0000 > 

So I try to find out which device I am using to set the --device parameter.

I try this:

root@ubuntu: sudo cat /dev/input/event0 text_here
^C
root@ubuntu: sudo cat /dev/input/event1 text_here
^C
root@ubuntu: sudo cat /dev/input/event2 text_here
^C

I check all the 'event' inputs but never receive a result. I tried this on my home computer and did receive a response from one the events. I simply cannot seem to figure out which 'event' is being used. No content is ever sent back to my cat command.

Is there a way to resolve this? Thanks for your help.
