First of all, let me emphasize that I am talking about my home computer that I use for personal use.
I have two accounts in Ubuntu: one for me, one for my wife. We don't use separate accounts to keep secrets from one another (as far as I know), but we do like having separate internet cookies and application settings.
Ubuntu makes it convenient to switch from one user to the other without logging out, but the issue I have is that when I switch from my account to my wife's account, the screen locks so that I must type my password again when switch back.
How can I make it so that the screen doesn't automatically lock under this circumstance?
