having a second DE in addition to LXDE, thus XFCE

[francois.e]

How do I install XFCE4 as a second DE for lubuntu xenial? Is it:
https://forum.ubuntu-fr.org/viewtopic.php?id=993881


sudo apt-get install xubuntu-desktop
https://askubuntu.com/questions/179148/set-default-user-session-to-xfce4

sudo apt install xubuntu-default-settings

And back into lightdm login manager:
select xfce4

Why not just install xfce4?
xubuntu-desktop will install the xubuntu desktop, which includes a few extras do-dads.

Answer:
There was a problem installing xfce with the iso. And as I was trying lubuntu to see how much performant on my old MSI-340x laptop, I realized that xfce offers much with less pain. In addition, I could revert to lxde DE if so is my wish.

Edited first post to include usb auto-mount packages gvfs and thunar-volman.

What ISO?

sudo apt install xfce4

That is all if you want to install xfce. You do NOT want to install xubuntu-desktop. That is equivalent to installing Xubuntu on top of your current OS. Not great. You only want the DE.
