After installing Xubuntu from its own iso, the desktop is slow to load up after putting in name and password. After installing Ubuntu, and then install XFCE through terminal, and deleting Unity, there is no slowdown. Please note, the slowdown only starts after the recommended updates are applied, not the required ones.
Xubuntu is a customized version of the xfce desktop for Ubuntu. It installs a slightly different theme, has some different defaults, and it installs a few custom applications.
