How can I persistently remap keys in Ubuntu 16.04?

This is working for the current session:

costales@dev:~/Desktop$ xmodmap -e "keycode 166 = less"

costales@dev:~/Desktop$ xmodmap -e "keycode 167 = greater"

Then I created this config file:

costales@dev:~/Desktop$ cat ~/.Xmodmap 

keycode 166 = less

keycode 167 = greater

costales@dev:~/Desktop$

But it's not working after a reboot. How could I force the remap to survive reboot?

I've been using 16.04 for a little bit and it seems to use sddm as its desktop manager. It used to be LightDM and GDM before that. Both its predacessors are documented to load ~/.Xmodmap automatically but I can't find anything explicitly saying sddm does.

Therefore it may be advisable to just force it to load with a new script. You just need to run xmodmap ~/.Xmodmap and you can do that a number of ways:

Adding it via the graphical start up tools

Editing ~/.xinitrc to run it.

Adding a new .desktop config in ~/.config/autostart/

There are probably a few dozen other ways to manage this, essentially doing the same thing.
