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) /usr/bin/xgps:444: Warning: invalid (NULL) pointer instance self.window = gtk.Window(gtk.WINDOW_TOPLEVEL) /usr/bin/xgps:444: Warning: g_signal_connect_data: assertion `G_TYPE_CHECK_INSTANCE (instance)' failed self.window = gtk.Window(gtk.WINDOW_TOPLEVEL) /usr/bin/xgps:445: GtkWarning: IA__gdk_screen_get_display: assertion `GDK_IS_SCREEN (screen)' failed if not self.window.get_display(): Traceback (most recent call last): File "/usr/bin/xgps", line 860, in <module> base = Base(deg_type=degreefmt) File "/usr/bin/xgps", line 446, in __init__ raise Exception("Can't open display") Exception: Can't open display address@hidden ~ $ I’m not sure what is causing this. Thanks. |
