Remove kde4 stable
Have you installed kde4 on your ubuntu box and you want if off your system asap?
I installed kde4 on top of the normal ubuntu (aka the gnome version), so I don’t know if this is usable for kubuntu.
In your gnome session, open a terminal and past this
sudo aptitude purge kde4 kde4-core
You might also want to remove the kde4 repository for obvious reasons.
Go to “system -> administration -> synaptic package manager”.
Once in synaptic click “settings -> repositories -> third party software” and remove the one that mentions kde4.
Then press the reload button on synaptic.
