Hi Xavi,
From last time we came accross the latin american keyboard, the
solution was in the end to just run the following in a terminal:
setxkbmap latam
To keep it permanently it had to be added to the ~/.xinitrc.
The suse layout tool is installed by default.
You can hit alt+esc and type layout, you should be able to start the
tool from there.
This along with some other issues I will try to address as best I can
in the petite 12.1 version, when it's ready.
Thanks,
Robert
