I start to wonder if it's possible to make a script to send notifications once to several other Ubuntus, i must say that not all the computers have the same Distro, having MATE XUbunutu LUbuntu and different versions.
It's reliable to do via ssh ?? I want to send this push notifications to one or two PC per office
I'll bring the first problem it occurred to me when tried in Ubuntu MATE 20.04
administrador@secto27:~$ export DISPLAY=:0
administrador@secto27:~$ notify-send "Titulo" "Hola"
