Upgrade Deb 7 to 8, GNOME Flashback, terminal windows not saved: any way to save?

[Tom Browder <tom.browder@gmail.com>]

I just upgraded and am disappointed that, even though browser
instances can be saved between login sessions, terminal windows
apparently can't.

I have used the gconf editor and found setting:

  apps | gnome-session | options | auto_save_session

which is checked, but the terminals still disappear after logging out
and logging back in.

Is there any way to recover that most valuable feature of the old GNOME desktop?

Thanks.

Best regards,

-Tom
