My Unity login option in GDM crashed after I installed the
kubuntu-desktop packages on my Ubuntu 11.04 install.
When I’m logging into, it runs Unity 2D (which was also installed on my PC). How can I fix that?
All other login options work correctly, only the Unity ("Ubuntu") option doesn't work.
By Login option, I meant Desktop Enviroment option, which you can choose at the bottom of the GDM.
