Black screen - cepicscepics - 2018-12-02

Hi, I was trying to instal MQTT plugin in SignalK,
the dashboard gave me an error and the server told me "restart required".
I tryed to restart only the server but the error still there, so I rebooted the pi, and on startup, no icons on the desktop,
so I rebooted again and, on new startup, the screen is Black on hdmi monitor and on vnc viewer..... but with mouse.

right click on the black screen I can open a terminal window ...

RPI 3B
OP 1.2.0
MCP2515
wireless mouse

Code:
pi@openplotter:~ $ openplotter
Could not stat /dev/ttyOP_ap: No such file or directory
Failed to initialize Interface ap
Could not stat /dev/ttyOP_gpsfix: No such file or directory

You can disable signalk by:
sudo systemctl disable signalk.service
sudo systemctl disable signalk.socket
sudo reboot
If system restarts open a terminal
cd /usr/lib/node-module/signalk-server
npm start
Now it should show you the error.

Black screen - tkurki - 2018-12-05

I can not think of a way that SK server causes a black screen. It is most probably something else.

Anything in syslog?

Sorry wrong path
cd /usr/lib/node-module/signalk-server
it should be
cd /usr/lib/node_modules/signalk-server

try again

btw: Are you sure that your raspberry pi works with another sd card?

I think the output of
sudo nano /var/log/syslog
is too long to post here!!!

RE: Black screen - e-sailing - 2018-12-05

When Signal K is already running you got this error.
You disabled Signal K but it is running after reboot. I don't know why.

sorry I was missing the first command!!

Code:
sudo systemctl disable signalk.service
sudo systemctl disable signalk.socket
sudo reboot

and then:
