I would like to be able to install XFCE to run alongside unity so I can choose, upon startup, which DE I use, without breaking any features of either DE.
Following this: Xubuntu 14.04 Trusty Tahr: a classic beauty
Note: don't install Nautilus in Xubuntu! This will cause system conflicts.
I don't want to affect ANY of the features in Unity, i.e. I want to be able to use the two interchangeably, so I can't follow some suggestions of just cleaning out all the old stuff as that would mean using Unity would be changed.
Can I install Unity aside with XFCE and switch them as I want? Is this possible in 12.04?
