A few minutes ago I decided to reinstall ubuntu-desktop (I currently have kubuntu installed). However, when I restarted my machine, I saw something a bit annoying: the loading screen still bore the Kubuntu logo and color scheme, and it took me to the KDM.
My question: How would I be able to get back to using the Ubuntu loading screen and the GDM?
In addition, I find that the GNOME Artwork Manager no longer loads; or rather, it appears to, but disappears for a split second.
Thanks in advance.
