Unity on Ubuntu on DeX.
Unity is the default DE of Ubuntu 16.04 and the Ubuntu image in Linux on DeX is one of the 2 gnome flashbacks, so unity is still there. Maybe, there’s a chance to get Unity 8 going too.
It’d be interesting to get the default Ubuntu 16.04 image as it should be, rather than the Ubuntu Gnome Flashback, even though I like the Flashback. Most probably, Gnome shell could be achieved.
