Previously I navigated to /etc/lightdm/lightdm.conf and changed user-session=ubuntu. lightdm.conf doesn't exist in Ubuntu 14.04 at that location, so how do I change user-session=ubuntu to something else?

14.04: 14.04

12.04: enter image description here

take a look in /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf for changing default session (to wipe out guest login,btw, you must modify /usr/share/lightdm/lightdm.conf.d/50-unity-greeter.conf )

Best regards,

I have Ubuntu 14.04 and Kubuntu installed. You can change environments from the login screen. Next to your username, where it asks for your password, click the small Ubuntu icon. It will open a drop-down menu, with your installed environments on it. Select your desired session from the drop-down menu, and login.

Here is a link to another question(answered) that describes the process of changing the default environment in Ubuntu 14.04. Should get you going.

I need as a default. So you don't always have to change via the launcher. I'm doing this because I want to have an ISO copy of my os and I don't use Unity I use Gnome-Panel (As I want to still be in the Gnome system) –  davidbuddy9 Jun 4 '14 at 15:52
@davidbuddy9 I see. See my amended answer. –  SonOfEntropy Jun 4 '14 at 16:37
