Two simple questions

Hi All,

I am new here. I met two questions after installing gnuradio-3.1.1. I
they are simple questions, but I really don’t know how to fix it and
your help. I am using fc7. I follow the Fedora installation instructions
the website, install every package it mentions. After installing
gnuradio, I
run several scripts to test the USRP. test_usrp_standard_rx works well
load the firmware, shows that the Max USB/USRP
throughput is 32MB/sec. However, when I run, it gives the

Xlib: connection to “:0.0” refused by server
Xlib: No protocol specified

( Gtk-WARNING **: cannot open display:

Can anybody explain this for me? I really appreciate any help!

Here is the 2nd question. I am using python2.5, and installing wxPython
synaptic. However, when I try to check wx.version, I met another

$ python
Python 2.5 (r25:51908, Oct 19 2007, 09:46:41)
[GCC 4.1.2 20070925 (Red Hat 4.1.2-27)] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.

import wx
print wx.version
Traceback (most recent call last):
File “”, line 1, in
AttributeError: ‘module’ object has no attribute ‘version

I appreciate any reply.
