But the first thing I noticed once I booted into Gnome 3 was that, when I closed my laptop lid, the system went into suspend mode. Not what I want to have happen: unless I'm on battery, I want the system to just blank the screen when I close the lid.
I went into power settings and could not find a setting for what to do when the lid is closed. Something that was very easy to find in past, but now is not obvious.
So a quick google search turned up this solution:
To set the action when the laptop lid is closed, simply enter the following commandline:
gsettings set org.gnome.settings-daemon.plugins.power lid-close-MODE-action “ACTION
where you replace MODE with either ac or battery depending on which mode you're setting, and replace ACTION with blank, suspend, hibernate or shutdown.
