I accidentally disabled plasma desktop on startup. How do I fix it?

[Guest]

Title pretty much says it. I went to the system settings and accidentally disabled the plasma desktop to autostart. How can I fix it now?

Thank you for your help.

PS: I cannot launch it via commandline using plasma-desktop, it gives me an error and says that the initialization of X failed.
DISPLAY=:0 plasma-desktop doesn't work either

You should be able to start it like this, so you should find out why you cannot and fix this first. I recommend trying the following first:

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install -f
sudo apt-get install kubuntu-desktop

To make sure your system is fully up to date and installed correctly.

If you still have problems launching it after I suggest creating a new user and see if it works for them, that will tell you if it is a configuration error or not.
