[Discuss-gnuradio] GNU-Radio GUI applications freeze

[Raul Siles]

Hello,
I'm running GNU-Radio 3.1.3 under Fedora 8 (fully updated) with USRP
and all the USRP graphical (GUI) applications freeze, such as
usrp_oscope.py or usrp_fft.py.

The application, eg. usrp_oscope.py, main window is displayed but only
the signal diagram is visible and changes. All the controls and
buttons are not available. Sporadically the whole window, signal
diagram plus controls, is displayed but it is not possible to interact
with or adjust any control.

I've also tried compiling the stable GNU-Radio 3.1.2 version, and even
with GNU-Radio and USRP from the Fedora yum repositories
(3.1.2-2.fc8). I'm experiencing the same behaviour with all them. The
GNU-Radio and USRP command-line tools work fine, so it seems an issue
with wxPython and Fedora.

I'm using the 2.6.25.14-69.fc8 kernel version and wxPython version:

# rpm -aq | grep wxPython
wxPython-2.8.7.1-5.fc8
wxPython-devel-2.8.7.1-5.fc8
#

The computer VGA card is an ATI model:
# lspci
00:00.0 Host bridge: ATI Technologies Inc RS200/RS200M AGP Bridge [IGP
340M] (rev 02)
00:01.0 PCI bridge: ATI Technologies Inc PCI Bridge [IGP 340M]
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon IGP
330M/340M/350M
...

Has anyone experienced a similar behaviour? Any help or hints to
troubleshoot this issue are appreciated! Thanks!
