CODEtextxset -dpms off No protocol specified Can't open display :0 To solve it ===

There are times when using the sudo command or, as in the example, the xset command, we encounter the following error:

CODE

text

xset -dpms off
No protocol specified
Can't open display :0

To solve it we execute the following:

Bash

echo «» >> $HOME/.bashrc && echo «export XAUTHORITY=$HOME/.Xauthority» >> $HOME/.bashrc && cd $HOME && . .bashrc
