Turning the System On and OffPermalink to Turning the System On and Off
When you turn on the primary computer, it will automatically log into the user sosdemo. The primary computer should be always on. The spare computer doesn’t have to be on, but it is recommended to leave it on for backup purposes. If you want to change users you will have to log out and then log in using your user name and password. There is an icon that looks like a power button in the top right menu bar for logging in and out.
To shut the system off use the icon that looks like a power button in the top
right menu bar. This lists many options including log out, shut down, and
shutdown -h now to shut down or
sudo reboot to reboot in a
terminal also works. To force a sudden power off hold the power button for 5
seconds. This last option is to be used only as a last resort.
