I installed this KDE Version with the commands from this link (on my Kubuntu 11.10) and after that i removed it with your commands because it freezes all the time.
But when i log in in Kunbutu it is always this version.
I tried with purge kubuntu* to remove all Kubuntu Pieces, but when after that I install kubuntu-desktop again it is again the newest ppa Version.
Can you help me to return to then normal Kubuntu-Desktop? When i will install it with synpatic, i always find only the version from ppa, but i removed ppa sources!
