Answer 1

Ubuntu for the Housewife:
1. Click the rightmost icon on the menu bar and select System Preferences.
2. In the Hardware section, click Power.
3. Set the drop-down menu next to When the lid is closed to Do nothing.

Answer 2

This is exactly how it works when setting up, as OnYourLips wrote. The screen is locked, but does not go to sleep.
Ubuntu 15.04, on 14.10 it was the same.
