===== Official Raspberry Pi Touchscreen =====

==== Rotating the Official 7" Touchscreen ====

Comment the following line in your ''/boot/config.txt'' (to disable this parameter):
<code bash>
# Enable DRM VC4 V3D driver
#dtoverlay=vc4-kms-v3d
</code>

And add the following line to your config:
<code bash>
# rotate screen
lcd_rotate=2
display_rotate=0
</code>

==== Run chromium in kiosk mode at startup ====

Firstly enable autologin and boot to desktop. Therefore you can use the ''raspi-config''-tool:
<code bash>sudo raspi-config</code>

And then add the following line to the user's ''lxsession'' config:
<panel type="info" icon="glyphicon glyphicon-file" title="~/.config/lxsession/LXDE-pi/autostart">
<code bash>@chromium-browser --kiosk --disable-pinch <url-to-open></code>
</panel>

==== Turn off screen automatically after a period of inactivity ====

To enable this "energy saving"-setting create a system service file under ''/etc/systemd/system/'' with the name ''screenblanking.service'':
<code bash>sudo nano /etc/systemd/system/screenblanking.service</code>

Then add this content:
<code bash>
[Unit]
Description=Automatic screen blanking
After=network.target network-online.target

[Service]
Environment=DISPLAY=:0.0
RestartSec=40
Restart=always
User=pi
ExecStart=/usr/bin/xset dpms force off

[Install]
WantedBy=multi-user.target
</code>

Finally save the service and enable it with:
<code bash>sudo systemctl enable screenblanking.service</code>
