I can't disable the Guest session for Ubuntu 12.04.
I tried to add allow-guest=false
but it doesn't work.
Is there another way to disable it?
You can use the method explained here: How to disable the guest account via the GUI?
Short version:
Install the ubuntu tweak from here: http://ubuntu-tweak.com/
Goto Ubuntu Tweak > Tweaks > Login Settings > Guest Account > OFF
First you need to hit CTRL+ALT+T to open the terminal. When you've opened the terminal you need to type: sudo sh -c 'echo "allow-guest=false" >> /etc/lightdm/lightdm.conf'
When you did that restart the computer and that's done ;)
Just follow the steps to disable the Guest account
