When I close the lid of my Asus X77JQ, lucid shuts it down automatically after five minutes. I want to be able to sleep in the same room as my laptop, so I would like to be able to close the lid without it shutting down. How can I do this?
The power options lid close option is set to do nothing.
You can set the action to other values, such as shutdown, blank or interactive, by using gconf-editor.
First, install dconf-tools, then launch gconf-editor from the Dash.
Navigate to org.gnome.settings-daemon.plugins.power.
The two items of interest are lid-close-as-action and lid-close-battery-action. Click the existing value to change it.
To quickly change the action to shutdown when the lid is closed, open a terminal window and run
gsettings set org.gnome.settings-daemon.plugins.power lid-close-ac-action shutdown
gsettings set org.gnome.settings-daemon.plugins.power lid-close-battery-action shutdown
The problem appears to be you have one setting for when user is logged in and another setting when you're at the greeter (lightdm).
I solved this problem by editing /etc/UPower/UPower.conf and changing IgnoreLid=false to IgnoreLid=true at the end of the file.
After restarting, closing the lid didn't put the computer to sleep anymore.
I used this question as reference: Stop laptop from suspending when closing lid in lightdm
Note: someone asked there if this wouldn't disable the lid behavior for every users. I really don't know.

Actions to take when closing the laptop lid are configured with command gnome-power-preferences (menu: System -> Preferences -> Power management)
You will need to set two options: "When laptop lid is closed" to "Do nothing", and also "Put computer to sleep when inactive for" to "Never" (otherwise the laptop won't sleep automatically when you close the lid, but will soon afterwards because it's inactive). Note that these options have separate values for "AC power" and "Battery power": of course, you'll have to configure the correct one for your case (or both).
*Note: You may have to run the following command for the option to show up:
gconftool-2 --type string --set /apps/gnome-power-manager/buttons/lid_ac "nothing"
