To remove Unity, I simply use dpkg -P packagenames. When that list becomes long

dpkg -l|grep -v ^ii
Of course, check if those lists of package names are okay to purge before doing
bulk purges. Some packages are tricky, see my post a while back on Unity
dependencies.
Thanks for your suggestion, Pander. I did something fairly similar to
that in the past. If I decide to go ahead this time, then I will follow
your plan because it seems simpler than what I did before.
However, I was hoping to receive advice that would be attractive and
useful to people who are not as confident as us with these low-level tools.
Am I correct in thinking the "old method" of installing gnome-desktop
alongside unity has become too complex to be worth trying?
I tried "sudo dpkg --purge --dry-run unity" (-P is the same as --purge)
on my xenial system "just for fun", but it bombed out with a "too many
dependencies" error. However, it didn't list ANY of them!
I turned on --debug=400 and saw a partial list, but couldn't get "2>&1"
redirection to work properly under sudo.
"dpkg -l | grep -i unity" gives a long list of packages... do you
recommend any of them as a starting point to drag down the whole tree in
a few big sections, or should I stuff them all into a purge packages file?
Perhaps I should just wait for the next ubuntu release and hope there
will be a more straightforward conversion path?

Brian
