Hi, I just reinstalled my slackware and I did the exact same thing I did before (edited lang.sh and lang.csh) and rc.local (to set unicode)
Here is how each one of them look like:
setenv LANG pt_BR
setenv LANG pt_BR.UTF-8
However it is not working as it was before, on tty it is but not on X.
(that is portuguese for "Command not found")
On tty and on my previous system it was working fine and display "comando não encontrado" (the correct way).
EDIT: My bad, guys. It was just on rxvt. I only realised it when I've tried xfce terminal. It is working fine
Damn I am such a noob
