How can I rename my computer? Renaming it in
/etc/hostname does something weird. Before renaming it, I am able to open these files via sublime using
sudo subl /etc/hosts
but when I rename my Computer (using nano) and open any of these files using
subl, I get this message:
No protocol specified (sublime_text:20071): Gtk-WARNING **: cannot open display: :0.0
So I guess renaming in the above files is not the only thing I have to do.
PS: If I rename using sublime, after renaming one of the files, I get same message when I try to open other file
