I have a Dell gamer model 7567, and I was using the 16.04 LTS version of Ubuntu and recently saw the need to format it. I have already installed the latest LTS version, (18.04) but I'm having trouble setting the keyboard to work with a Brazilian layout.
I found a solution that solves my problem but every time I reboot the system it returns to the previous standard.
This is the command that I am using every time I reboot the system:
setxkbmap -model abnt -layout us -variant intl
Would I have some way to leave this script set up so I do not have to run it every time I turn on the notebook?
