"No candidate" when I try to install Gnome Classic on 15.04. Will that change? If not, what other "low-tech," lower-demanding UI options do I have for my older, weaker computer with 15.04?

An official Ubuntu based distribution is Ubuntu GNOME 15.04.

GNOME Classic session is included. To try it, choose it from the Sessions option on the login screen.

You can use the GNOME3 PPA and update GNOME3 with these commands:

sudo add-apt-repository ppa:gnome3-team/gnome3
sudo apt-get update
sudo apt-get upgrade
  • I don't get the gnome classic session as I do get in Debian 8. Any hint? May 5, 2015 at 20:23

Open a terminal an run this command:

sudo apt-get install gnome-session-flashback

Logout and select your preferred classic session and login back.

  • I'ts similar bit not exactly the same, gnome classic opens the gnome 3 dash if you press the win key so it works as both gnome 2 and gnome 3 May 5, 2015 at 19:51
  • Thanks! It worked fine. It seems this package isn't exactly gnome-classic, but it's what I've been using for the last two years thinking it was. Now that I'm at 15.04 this was exactly was I was looking for.
