Depending on your selection here, you may be offered further screens to fine tune your choice. After the selection step(s), you will see a slide show during package installation. The slide show can be disabled by pressing the Details button Choose whether you prefer to use the KDE or Gnome desktop environment. Both come with a full set of useful applications and tools. Tick Custom if you want to use neither or both, or if you want something other than the default software choices for these desktop environments. The LXDE desktop is lighter than the previous two, sporting less eye candy and fewer packages installed by default.
