I use Ubuntu 10.10 on a laptop. I changed the "blank screen" settings at "System preferences -> Power management" and "Screensaver" and when I am logged in I can close the lid without going to sleep.
However, when I am at the login screen where I can choose a user, the behaviour is different. Ubuntu hibernates when I close the lid.
How can I change this so that only the screen blanks when I close the lid at the login screen?
