Black screen

[cepicscepics]

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 ...
