I have a fresh install of Ubuntu 13.10. I wanted to try out Lubuntu, so I installed the package lubuntu-desktop. Everthing worked fine, I can do Lubuntu sessions now, as well as normal Ubuntu sessions with unity.

I realized that I liked unity better. Unfortunately, since I installed lubuntu-desktop my login screen and my notifications look different. How can I revert this and get my old Ubuntu look back?

I already removed the package lubuntu-desktop, but it did’t help. Also, when I installed it, it came with a lot of packages that weren’t removed when I removed lubuntu-desktop

You need to remove all these packages:

  • Wow, that’s a bunch of code… There are some packages in 13.10 that are newer: libabiword-2.9 is now -3.0, libmenu-cache2 is now 3, libobrender27 is now 29, libobt0 is now 2. – Wauzl Oct 26 '13 at 17:48
  • Everything looks fine now except for the login screen which now looks like the one of lubuntu but an ugly gtk design. Also, I had to reinstall chromium-browser, texlive-full (only metapackage), banshee and had to remove indicator-network which was doing pretty much the same thing as the network-manager. – Wauzl Oct 26 '13 at 18:55
  • Hi, sorry didn't notice that you had 13.10. I've edited the list of packages. To get the ubuntu login manager, Install lighdm. Sudo apt-get install lighdm – vegard torvund Oct 26 '13 at 21:22
  • lightdm is used by lubuntu, as well. I tried sudo apt-get install --reinstall lightdm but it didn’t fix it. – Wauzl Oct 27 '13 at 07:00
  • Tried installing gdm, purging lightdm and then removing gdm and installing lightdm. After I figured out how to get lightdm running again, the login screen still looks ugly… – Wauzl Oct 27 '13 at 07:59
  • Figured out that I need lightdm-webkit-greeter. After installing I did sudo /usr/lib/lightdm/lightdm-set-defaults --greeter lightdm-gtk-greeter. After that lightdm only showed a black screen with no functionality. No errors were in the logfiles. I switched back to lightdm-gtk-greeter. – Wauzl Oct 27 '13 at 09:59

    Ok, I think I got it now. I did sudo /usr/lib/lightdm/lightdm-set-defaults --greeter unity-greeter and all is well now. Thank you :) – Wauzl Oct 27 '13 at 10:50
  • you did the most of the job yourself :) – vegard torvund Oct 27 '13 at 19:52

There is a GUI way of doing this that allows you to switch between Lubuntu and Ubuntu at will. (or any other desktop environment you choose.

Install the Graphical Alternatives Configurator (link to apps.ubuntu.com with quick install link to software center) or in a terminal
sudo apt-get update && sudo apt-get install galternatives
or search in the software center for galternatives galternatives via software center

Then open the Graphical Alternatives Configurator from the dash by typing galter

galternatives from the dash

You can change the boot screen (called Plymouth)

G Alternatives Plymouth Configuration

And the LightDM greeter (where you type in your password)

LightDM Greeter Config

You can then in the Unity Greeter choose Lubuntu by clicking on the Ubuntu ball logo just to the right and up from your username.

In the Lightdm Greeter you can select different desktops using the icon in the very top right corner and then the left most icon.
