Since the release of Ubuntu 11.10 Oneiric Ocelot, the default display manager become LightDM instead of Gnome Display Manager “GDM”. Ubuntu developers added the their own personal touch to LightDM by integrating Unity Greeter theme with. In this post we will check a couple of ways to change the background and logo of LightDM unity greeter on Ubuntu 11.10 Oneiric Ocelot.
1. No additional application required for this way
In this way we will change the background and logo of LightDM by modifying the Unity Greeter configuration file “unity-greeter.conf”
Run Terminal, then open the file “unity-greeter.conf” inside this directory path.
Here in the screenshot down bellow I used “nano” text editor. If you prefer a graphical user interface text editor such as “gedit” you can use it by typing.
As you see in the screenshot the second line shows the background path you can replace it with any image you want, and the third line shows the logo path you can change it as well or remove the current logo if you don’t need it.
2. The second way to change the background and logo requires Ubuntu Tweak 0.6
This is a much quicker way to change the background and logo of LightDM. If you don’t have Ubuntu Tweak 0.6 check installation instruction in this post Ubuntu Tweak 0.6 For Ubuntu 11.10 Oneiric Ocelot.
Run Ubuntu Tweak, open Tweak tab, then open “Login Settings” beneath ”Startup”. Now unlock the login settings with your root password, finally you will be able to modify the background and logo.
3. There’s a third way to change the LightDM background and logo using application called “Simple LightDM Manager“, unfortunately it didn’t work with me. If anyone of you guys have used it before, please leave a comment down bellow.
That’s it for now.
