How do I hide a particular user from the login screen on a default install of 11.10 and higher? (ie. using Unity Greeter)?
I used to edit the startup script for the GDM (/etc/gdm/Init/Default) to permanently change my display resolution.
How can I do this with LigthDM in Ubuntu Oneiric?
How do I disable the guest session in Ubuntu 11.10 or higher? I don't want people to be able to use my computer without using a password to log in!
What is the difference between GDM and LightDM? How can one switch between them. I mean if I have selected LightDM during installation process, will I be able switch to GDM?
I would have expected System ▸ Administration ▸ Login Screen ▸ Play login sound to control this, but unchecking it does not prevent the drum beat sound from playing.
