@Juanito:
Did you try the setxkbmap command?
Yes, and it works!
setxkbmap -model pc105 -layout latam -variant deadtilde
All is alright!
@Rich:
Today, I will try your suggestions and inform about results.
This line:
Code: [Select]
Option "XkbVariant" "deadtilde,deadtilde,"
appears to have an extra comma after deadtilde.
I've defined three layouts in this order: latam, es, en.
latam and es layouts has deadtilde variants, en has not. So, I set this extra comma to expicitly confiure variants for each layout... I suposse that a null string after comma correspond to en layout.
BTW: I've discovered that correct layout for english US is us, NOT en.
I will modify my /usr/local/share/X11/xorg.conf.d/01-xorg.conf before try your tips.
Thanks you, TCL developers and maintainers, for your kindly support!
