SCREEN SAVER
AMOLED screen has advantages of high contrast, wide color range, wide view angle
and so on. However, it is easy to face burn-in problem if displaying same content for
long time. As we test, the AMOLED cannot be restored if it display same static
image for 168 hours because of burn-in problem. In this case, we recommend you
to set screen saver and do not let the AMOLED display same static image for long time
（cannot longer than 1h）.
You can install screen saver with command below:
sudo apt-get install xscreensaver
