In Linux Mint the packages ir-keytable and v4l-utils are separate. I've 
installed ir-keytable but not v4l-utils. Are both packages required?

I don't have a /usr/lib/udev/rc_keymaps/ but I do have a 
/lib/rc_keymaps, and many keymaps are in that directory. I've copied the 
one I believe is correct to /etc/rc_keymaps/ as suggested. I've rebooted 
and run ir-keytable -v -t. The number keys have a response, but they 
don't appear as scancode and keycode, just their numeric value, e.g. 
pressing 1 results in a 1 on the screen. Few other keys have a response.

Something is stopping ir-keytable from showing the keycodes. I tried 
this with MythTV running and with it shutdown; the results were the same 
in both cases.

Anyone else experience this problem?
