Basically the greeter has changed to the greeter usually used in xubuntu. I did install the xubuntu desktop package over kubuntu, but I've removed it by now. however it's managed to reinstall itself(I did confirm that it was removed). What is going on.
Edit for clarity: What I mean is, unity has it's greeter to log in, KDE has its own, and so does xfce. I'd first installed kubuntu then switched it to XFCE for the desktop, which also gave me the XFCE greeter then to unity which gave me the unity greeter. then I uninstalled XFCE and its packages. however when I restarted my computer the XFCE packages were re-added and the greeter had been switched to that of XFCE which I'm now unable to get rid of which is what I'm trying to do.
