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
reboot. Typing 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.
When first logging in to the SOS machine, you will see the SOS desktop.
To the right of center is the SOS Projector Control GUI, which is used
to control and troubleshoot the projectors. In the lower right corner
is the SOS decorative graphic, which is shown on SOS desktops since
release 5.2. In the center is the SOS Stream GUI, which appears when
SOS is started. In the upper right corner, the current user will be
shown (normally either sos or sosdemo) and the number 1
or 2, depending on which SOS machine you're logged into. In the upper
left corner are four desktop icons to launch applications.
