Just to clarify my comment. If you do not want to see the custom "Ubuntu" session with Gnome extensions that cannot be disabled, you can do the following:
1. from terminal, install gnome session: sudo apt-get install gnome-session gnome-session-wayland 2. logout. 3. on login, click the gear icon, select Gnome instead of Ubuntu. 4. Done, you can now enjoy Ubuntu with vanilla Gnome session. Couple of notes: - I agree with comments by Joseph Jasson. Having said that, I understand how Canonical is trying to help its user base with a smooth transition, and I appreciate the effort. If "Ubuntu" session's extensions cannot be tweaked it would be great if those few extensions could have their on/off button greyed out or removed, just for clarity. - Ubuntu-Gnome is no more as far as I understand, so Ubuntu 17.10 will have to serve both Unity and Gnome fans. With this in mind, I believe it would be great if gnome-session gnome-session-wayland could be installed by default. This could help users switch to the desktop environment they prefer.
