[mythtv-users] Remote numeric keys no received

[R. G. Newbury]

I am running mythtv 29 on Fedora 28. My remote is a Harmony 330. The 
receiver is an Imon Pad, using the evdev driver.
I have an /etc/rc_keymaps/imon-pad file which has the correct hex codes 
seen by evtest. The majority of the keys are mapped and passed through, 
and work within mythtv, as expected.

However, the numeric keys 0-9, are never passed through. They appear to 
send codes in the 500 range, according to xev.

(The keyboard sends everything, as expected..)
Some google-fu lead to the following addition to xorg.conf

Section "InputDevice"
     Identifier     "RF remote"
     Driver         "evdev"
     Option         "Device" "/dev/input/event7"
     Option        "event_key_remap" "512=19 513=10 514=11 515=12 516=13 
517=14 518=15 519=16 520=17 521=18 522=231 523=104"
EndSection

But this does nothing.

Does anyone have a clue what is/is not happening? It would be nice to be 
able to jump by an exact number of minutes.
