Ok, sorry for this, it is my first time trying to file a bug in Debian and it has been years since I filed a bug at all.
1) Before I filed the bug I had been trying with documentation and internet pages to fix my issue, what I really want is that my BRAND NEW variation on us(intl) called us(brz) would be usable both in the console and in X. 2) I succeeded in making X use my variant, but only when I do a 'setxkbmap' command it works in X, and I wasn't able by myself to make any changes in console. 3) console-setup and keyboard-configuration do NOT find my us(brz) variant. 4) After I edited the /etc/default/keyboard file I did several 'setupcon -v' and 'reboots' and nothing changed. 5) Now I reinstalled Debian, put my modified /usr/share/X11/xkb/symbols/us file in place, changed my /etc/defaults/keyboard file and now the console works fine, this bug should be closed in my view 6) I still can't seem to make these changes propagate to X (even with the triggers in 'udevadm'), but I have a small call for 'setxkbmap' in my .bashrc so it is a matter of always starting X with a X-terminal and my changes have effect I thank you guys for the help and seems I had just tried too hard to fix a issue I must have broke myself with a lot of different configuration tutorials out there. The Debian Wiki by the way was no help at all in this. Thanks again Rogerio
