Looking at the link you followed to lock the screen on lid close you need to follow these steps to have a regular suspend
when the lid is closed.
Set Ubuntu Power Settings
From the Launcher select the cog for System Settings
. Click the icon Power
and this screen appears:
Look at the line When lid is closed
and set the options as they appear above to Suspend
.
Close the window.
Set systemd logind.conf settings
Invoke the Terminal
by pressing Ctrl+Alt+T. Edit the systemd logind.conf file by typing:
gksu gedit /etc/systemd/logind.conf
Look for these two lines and change them to look like this:
HandleLidSwitch=suspend
HandleLidSwitchDocked=suspend
You might have to change ignore
or lock
to read suspend
. You might have to remove a leading #
.
Save the file and quit gedit
. After ensuring no applications (like word processor, spreadsheet, etc.) have files open type into the terminal:
sudo reboot
Voila! everything is reversed and your system will operate as you expect.
