I have update the raspi-config to start with command line and text boot.
But error still here.
Any one can help me???
And I can run
startxto show the desktop screen on the monitor. only npm start is not work.
@yohu12 do it in two steps
export DISPLAY=:0 npm start
It return same error
(electron:1493): Gtk-WARNING **: cannot open display: :0
@yohu12 this is the same as MagicMirror/installers/mm.sh
Are u doing this over vpn?
Also the operating system must have xwindows running…
I saw this error because the raspi was set to Autologin as “pi” and I had created another user which could not take control of the display.

I saw this just yesterday (followed by a few other warnings). Solution was to follow pretty much this ancient but still working how-to for jessie:
(especially points describing “Install Xserver, LXDE-gui and lightdm” and missing packages)
