On first script invocation stdout reports:

INFO     .Xauthority file '/var/run/sddm/xauth_zGOcOM' located        main.py:34

Subsequently we correctly see:

DEBUG    Adapter '/dev/ttyACM0' initialized                          main.py:211
DEBUG    Env variable 'DISPLAY' set to ':0'                          main.py:227
DEBUG    Env variable 'XAUTHORITY' set to                            main.py:200
         '/var/run/sddm/xauth_zGOcOM'

At this point behavior is as expected. Key presses via HDMI CEC are recognized, parsed and translated into xdotool commands.

On second and all future executions (for example when entering a Kodi instance and then leaving it) we see two .Xauthority files instead of one:

INFO     .Xauthority file '/var/run/sddm/xauth_GXWplh                 main.py:34
         /var/run/sddm/xauth_JpuFTA' located

main.py does not cleanly deal with this situation and instead does:

DEBUG    Env variable 'DISPLAY' set to ':0'                          main.py:227
DEBUG    Env variable 'XAUTHORITY' set to                            main.py:200
         '/var/run/sddm/xauth_GXWplh
         /var/run/sddm/xauth_JpuFTA'

Where especially setting XAUTHORITY to a multiline string is nonsense. Key presses are still recognized correctly but no longer translated into xdotool commands:

INFO     Key press 'OK' detected (CEC key ID '0')                    main.py:154
Authorization required, but no authorization protocol specified
Failed creating new xdo instance.

Investigate and find a sensible solution.

Workaround for now: Stay inside Kodi, do not leave else you'll be unable to reenter without keyboard input.
