The segfault can be avoided with LIBGL_ALWAYS_INDIRECT=1, eg,
$> LIBGL_ALWAYS_INDIRECT=1 usrp_oscope.py

thats very useful to know

Although this slows things down a little bit, it should still be faster than pure software rendering.

I would be interested in reports from other people, especially which chipsets/drivers segfault and which dont.

perhaps we can start a wiki page, with chip sets, error messages, versions, and recommendations.

Who else has GL working, or has GL issues, what is chipset?

A quick way to enable the gl sinks if not done so:

mkdir ~/.gnuradio/
echo [wxgui] >> ~/.gnuradio/config.conf
echo style=gl >> ~/.gnuradio/config.conf
