[gpsd-users] gpsd-clients: xpgs: could not open display

[David Murray]

Hi,

To start off, some information about my current set up:

- Raspberry Pi (model A) running Raspbian.

- Adafruit Ultimate GPS Breakout v3.

- gpsd: 3.6 (revision 3.6).

I have been using cgps successfully for the last couple of weeks, and I wanted to try and use its graphical older brother, xgps. First, I started gpsd using the following command:

sudo gpsd /dev/ttyAMA0 -F /var/run/gpsd.sock

Then, I launched the X server using the ‘startx’ command and after a few seconds I was able to see my desktop on my HDMI monitor. However, I ran into some issues with xgps.

address@hidden ~ $ xgps

/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display

  warnings.warn(str(e), _gtk.Warning)

  self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)

  if not self.window.get_display():

    raise Exception("Can't open display")

Exception: Can't open display

I’m not sure what is causing this.

Thanks.
