====== How to autostart application with systemd ======

==== Example for creating Qt application autostart on TQMa6x BSP ====


1.Create file ''/etc/systemd/qtdemo.service'' with following content:
<code>
[UNIT]
Description=Start Multitouch Qt Demo

[SERVICE]

[Install]
WantedBy=multi-user.target
</code>
2.Create file ''/lib/systemd/system/demo.service'' with following content:
<code>
[Unit]
After=multi-user.target
Description=start Qt demo

[Service]
Type=forking
RemainAfterExit=no
ExecStart=/lib/systemd/systemd-demo start
ExecStop=/lib/systemd/systemd-demo stop

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

3. Create file ''/lib/systemd/systemd-demo'' with following content:
<code>
#!/bin/sh
# launch demo application
#
export QWS_MOUSE_PROTO=tslib:/dev/input/event1
export TSLIB_TSDEVICE=/dev/input/event1
DEMO_PATH=/usr/bin/qwt-6.0.1
DEMO_EXEC=oscilloscope
DEMO_OPTS=-qws

case "$1" in
        start)
                echo 0 > /sys/class/graphics/fbcon/cursor_blink
                echo 0 > /sys/class/graphics/fbr0/blank
                /bin/mount -o remount,rw /
                /usr/bin/ts_calibrate
                /bin/mount -o remount,ro /
                ${DEMO_PATH}/${DEMO_EXEC} ${DEMO_OPTS} &
                ;;
        stop)
                killall ${DEMO_EXEC}
                ;;
        *)
                echo "Usage: $0 {start|stop}"
                exit 1
                ;;
esac
exit 0
</code>

4. make ''/lib/systemd/systemd-demo'' executable.\\

5. create symlink ''demo.service'' in ''/etc/system/system/multi-user.target.wants'' that points to the file ''/lib/systemd/system/demo.service'':
<code>
cd /etc/systemd/system/multi-user.target.wants/
ln -s /lib/systemd/system/demo.service demo.service
</code>
