Hello. I cannot figure out how to stop the screen from going black after a few minutes. I followed these instructions and it is still doing it.
"Step 3
Let’s disable the screen saver and screen blanking as well. This needs to be done in two places. First in the autostart configuration:
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart
And add the following to the bottom of the file:
@xset s noblank
@xset s off
@xset -dpms
Next in the X-windows manager configuration:
sudo nano /etc/lightdm/lightdm.conf
Scroll down to the [SeatDefaults] section and look for the xserver-command line below that. Change the line to look like this:
xserver-command=X -s 0 -dpms (so you’re removing the # on the front, and adding the missing bits at the end.) Again, hit CTRL-X and say Y(es) to saving the file.
Step 4
A Raspberry Pi is configured to automatically shutdown parts of the hardware that aren’t actively in use. This includes the WiFi driver. This will cause MagicMiror² to occasionally fail to fetch updates for things like the newsfeed, weather, and others. You can disable the power saving feature for the WiFi from the interfaces configuration file:
sudo nano /etc/network/interfaces
Find the wlan0 section and add wireless-power off below it:"
