(Please dont be turned away if you arent familiar with KDE, this can all be done via the command line, I just need to be told what to do, this can apply to any ubuntu software!)

I followed the following guide to install the latest version of KDE on my system: http://www.noobslab.com/2013/02/install-kde-410-in-ubuntu-12101204linux.html

I quickly realized that this version of KDE is simply not meant for the version of Ubuntu that I have(Ubuntu 12.04.2 LTS), and eventually, I need to do something about that. But for the time being, I need to undo what was done here and get my old version of KDE back.

So what I'm thinking I need to do is uninstall KDE, remove the repository of the latest version of KDE, and reinstall KDE from the official repository. The problem is I dont know how to do that, because I dont know what im looking at in my source list

Here are the commands I entered to be able to install the newest KDE

sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt-get update
sudo apt-get dist-upgrade

heres my sources.list. Maybe I can simply remove something here?

You don't need to uninstall KDE, just force the version to a lower one. You can do it all in Synaptic, although there are command-line equivalents.

The repository that you added is probably in sources.lst.d.

apt-get --force-version something something. Have a look in the man page. I'm on my phone, so I can't really check for you.

Aptitude is a good command-line option too, although I don't think it's installed by default any more. You can give it apt-get style commands, or just invoke it for the same kind of thing as Synaptic, but on the command line.

You can force package versions in the synaptic package manager by viewing versions under properties. This is a long process and it may be quicker to backup and re-install. Using aptitude (not apt) from the command line would require knowing the package names and chances are the are many. Investigating a PPA purge may be useful as well.

You can use ppa-purge to do it all for you.

sudo apt-get install ppa-purge
sudo ppa-purge ppa:kubuntu-ppa/backports

This will remove the KDE PPA you added and revert all of the updated packages back to the versions in the standard repositories.

I did that, now when I start the computer it drops to terminal. I try to type kstart and it says cannot connect to x server.
