Global Menu on MATE: Fail!

Tried to make the Ubuntu's own Global Menu solution to get going on MATE, to no avail...
Used the instructions given here: HOW TO GET A GLOBAL MENU IN MATE DESKTOP.
(Specifically, the last post as of today...)
Which says to do this on a MATE 32 bits:

sudo apt-get install indicator-sound-gtk2\
indicator-application-gtk2 indicator-datetime-gtk2\
indicator-session-gtk2 indicator-messages-gtk2\
firefox-globalmenu indicator-appmenu appmenu-gtk\
appmenu-gtk3 appmenu-qt

Followed by a reboot.
The desktop never got back :)
After login, it belched an error, it couldn't start GNOME, and died.
So, commands over the internet... Caveat Emptor ;)
Luckily that was on a box that was planned to reboot.
