How can I change Edubuntu to Ubuntu? (Previous question was never answered).

You can try the following:

sudo apt-get install ubuntu-desktop
sudo apt-get remove edubuntu-desktop

Similarly, to move from ubuntu to kubuntu you may be able to do

sudo apt-get install kubuntu-desktop
sudo apt-get remove ubuntu-desktop

If you are moving from ubuntu to kubuntu you will want to be sure to choose kdm as your default display manager when prompted. However, there is really no reason you need to remove ubuntu-desktop and both can live happily on the same ubuntu installation.

May I add to remove the old packages belonging to edubuntu use
Sudo apt-get autoremove

Hope that helps
Shane

Thank you for the advice, but during startup it still displays Edubuntu.
I am not sure what I did. I went to www.ubuntu.com and downloaded Ubuntu 9.04 and ended up with Edubuntu.
I might have changed it to Edubuntu when I activated some of the educational software. I deactivated it in my first attempt to bring back Ubuntu though.

First be sure to follow shane fagan's advice and run sudo apt-get autoremove.
To get the ubuntu start-up screen you just have to select it. To do that you can do the following:

sudo update-usplash-theme

This will output a list of the available theme's. You should see: usplash-theme-ubuntu. If you do, run the command:

sudo update-usplash-theme usplash-theme-ubuntu

Thank You once again, but Edubuntu still appears at startup. I am still very new to Linux. How can I tell if I have Ubuntu or Edubuntu even if the start up screen says Edubuntu?

If you have ubuntu-desktop installed and have uninstalled edubuntu-desktop then you have Ubuntu. The splash screen you see on start-up simply needs to be reconfigured to the ubuntu theme, which is what the command I gave you was intended to do.

Just to clarify before going forward, by "at startup" do you mean the splash screen with the progress bar or the screen at which you have to put in your username and password?

Yes. The startup screen which I place my name and password says Edubuntu. The other startup screen says Ubuntu.
Sorry about the confusion.

No problem, I should have asked at the outset.

The login screen can be changed very easily from the system menu. By going to System->Administration->Login Window and then going to Local tab and selecting the log in screen you would like to see from the list of pictures on that tab. (To ensure you have selected the theme, make sure that the circle next to the picture is filled in).

I think I might have had Ubuntu the entire time, but the background changed randomly without my permission. I had to manually change it back. I did not know the sign in screen could also be changed that easily. I think it was changed along with my background. Now everything is back to the way it was.

Thank You for the help.
