I installed some KDE stuff by mistake. After removing it, my login screen now is quite different; has a white background and the user icons+input appear in the centre.

[note that I have tried sudo dpkg-reconfigure lightdm; amongst other things]

How do I revert back to the default Ubuntu 13.10 x64 desktop one?

You just have to edit your /etc/lightdm/lightdm.conf file, and change this line

greeter-session=lightdm-kde-greeter

to this one

greeter-session=unity-greeter

Or simply reconfiguring the greeter (not the Desktop Manager) might work also:

sudo dpkg-reconfigure unity-greeter

In /etc/lightdm/lightdm.conf I changed greeter-session; should I change: user-session=kde-plasma also? - If so, to what? –  A T Jan 2 at 12:13
    
(also I wasn't testing out a new desktop environment, I was installing some editor or IDE IIRC; which had a bunch of deps) –  A T Jan 2 at 12:14
    
@AT: Oh, someone kinda boosted up my answer. I only wrote ca. the last 10 lines of the answer. Changing the greeter-session will give you back your login screen. (Did it work?) The user-session is just the default graphic session which loads after you login. You can change it back to ubuntu if you don't want KDE as default, but you can always change the user-session on the login screen also if you want to switch. (regarding the installation, next time you might want to install with sudo apt-get install --no-install-recommends PACKAGENAME ) –  falconer Jan 2 at 12:26
    
@NikTh I did a rollback because your edit is added too much new information to my answer, which changed my answer too much. Please consider adding a different answer, not an edit if you have that much more to add. (Even if our answers will overlap in some points.) –  falconer Jan 2 at 18:44
    
Thanks, that did the trick –  A T Jan 13 at 11:28

For me

sudo apt-get purge lightdm-gtk-greeter

did solve the issue

It will solve it, but this can damage things... –  Tim 4 hours ago
