I have built a desktop from old bits for a Linux friend ( Ubuntu 14 ) to replace her 0.75GB system which is a trifle slow!
I have kept my account as Administrator, in which I have installed gnome-session-flashback, and want to install it likewise in the new user's account (which has the dreaded Unity Desktop).
Not knowing how to do that from my Admin account, I tried temporarily giving the user administrator pivileges but the apt-get command from her account tells me that she is not on the sudoers list - and my password doesn't work, of course.
What the easiest way of installing the gnome flashback desktop on a secondary user's account?
Your advice would be very welcome.
