I Uninstalled Lubuntu, But Not Only Is It Still There: It's Pervading My Other Shells

[Shie6meepo]

I uninstalled Lubuntu and LXDE after realizing that I didn't need such a low-use environment and that Xubuntu and plain 'ol Ubuntu suited my tastes more. However, it still shows up in the login menu and I can still run it just fine, like it was not uninstalled. In addition, my startup and shutdown screens are the Lubuntu screens, not the Ubuntu ones.

I did not install LXDE before regular Ubuntu; it was added on through the software center. Any ideas?

Did you remove the lubuntu meta package or single packages?

I am guessing that from a Ubuntu install you installed LXDE. Is that correct ot did you install Lubuntu over the Ubuntu install? If it is still listed on your log-in list then it was probably not installed since you can still boot into it and use it. Which procedure did you use to un-install, terminal, Software Center, or Synaptic Package Manager? It obviously didn't work so try again.

I installed 12.04 LTS with a flash drive, then installed Lubuntu through the Software Center. I have since uninstalled the main Lubuntu package through the Software Center, and Software Center claims that LXDE and Lubuntu are not installed on my sytstem.

Have a look on the following page, and your answer is the code under the title:
Remove Lubuntu

http://www.psychocats.net/ubuntu/pureubuntu

OR

just copy-paste the following into a terminal to completely remove Lubuntu from your system and go pure Gnome. (use at your own risk after backing up your data)

That worked for the most part, but now my startup and shutdown screen is showing the Xubuntu screen. While I like that startup screen a lot, it seems like false advertising to me, so I guess I may want to attempt the same type of code to Xubuntu. However, I don't want to go back and reinstall some of my programs like I did when not being careful last time.

[dummy910]

let's say one wanted to install gnome display login manager, in a terminal they would type the following:

sudo apt-get install gdm

then:
reboot

Unless I'm completely off here, it's not the display manager that's the problem. I have LightDM fully functioning, but the only thing that's not right is literally the screens when you start up and shut down, where the logo and progress dots are displayed. I'm getting the Xubuntu one with a blue bar sliding back and forth and the Xubuntu logo.

Thanks for the help everyone, especially he who posted the system purge link. Though I did lose a few programs that I had to reinstall (my own fault), I got everything back to normal. Time to experiment with Cairo Dock and see what I can screw up there.
