i see someone asked how to change in unity top left corner label (ubuntu desktop) there is an answer but it is no very clear, can someone explain it with more details, i am pasting the answer that was posted but i need more directions, thanks

You would likely need to build the unity or unity-2d source. Currently in unity-5.12 would be found in /plugins/unityshell/src/PanelMenuView.cpp, line 78

_desktop_name(_("Ubuntu Desktop"))

In unity-2d, unity-2d 5.12, /panel/applets/appname/appnameapplet.cpp line 369

d->m_label->setText(u2dTr("Ubuntu Desktop"));
