Ubuntu11.10 started with the Guest session mode, so someone had this problem: Can I disable or enable Guest Account (Guest) login like Windows?

Ubuntu 11.10 started with the Guest session mode, so someone had this problem: Can I disable or enable Guest Account (Guest) login like Windows?

In Windows, it is very simple, but what should I do in Ubuntu 12.04.

The following is an effective solution:
(1) run in the terminal:

Sudo gedit/etc/lightdm. conf
[SeatDefaults]
Greeter-session = unity-greeter
User-session = ubuntu

(2) Add allow-guest = false, that is, the following content:

[SeatDefaults]
Greeter-session = unity-greeter
User-session = ubuntu
Allow-guest = false

(3) Save and exit. OK!
