    Down grading Desktop Environment

    (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/inst...1204linux.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?

    Re: Down grading Desktop Environment

    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.

    What are the command line equivalents?

    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.

    Re: Downgrading desktop environment

    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.

    Re: Down grading Desktop Environment

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