WX GUI Widget Error: The program 'python2.7' received an X Window System error

GNU Radio

Hi all,
i’m newbie to gnuradio (and ubuntu).
I have installed Gnuradio 3.6.4.1 in Ubuntu 11.04 (i386) on a VM.
When I execute a simple flow graph with WX GUI Scope Sink (or WX GUI FFT
Sink or WX Waterfall Sink), I get the following error (view attachment):

The program ‘python2.7’ received an X Window System error.
This probably reflects a bug in the program.
The error was ‘BadMatch (invalid parameter attributes)’.
(Details: serial 1261 error_code 8 request_code 73 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error()
function.)

Any help will be appreciated!
Thanks
Claudio

Hi Claudio
Could you attach the kernel log?

Hi Sergio,
thank you for reply, but I think that the kernel log isn’t inherent with
my problem.
I think the error is likely due to some problem in OpenGL, because when
I change the ~/.gnuradio/config.conf to use “nongl” for wxgui, it works
fine.
