Open GL support

spyder3 fails while starting with this error
[13936:14070:0620/132454:ERROR:gl_surface_qt.cpp(251)] glXCreatePbuffer failed.

I have loaded Mesa and libGLX to execution path. Which additional libraries are required?

'spyder', '3.1.4',
Python 3.6.1
Qt 4.8.7
PyQt5 5.8.2
Mesa 12.0.2
freeglut 3.0.0

I think this will be fixed in Spyder 3.2 because we added pyopengl as a new dependency to fix this kind of errors.

3.2 will be released in a couple of weeks. In the meantime, please take a look at #4601 for the solution.

@ccordoba12 I'm seeing this exact same issue currently with Spyder 3.2.5 and with PyOpenGL (3.1.1a1) in place:

$ spyder3
[18391:18548:0111/213943:ERROR:backend_impl.cc(1385)] Unable to map Index file
[18391:18557:0111/213943:ERROR:gl_surface_qt.cpp(251)] glXCreatePbuffer failed.
Segmentation fault

I also tried after $ export GALLIUM_DRIVER=swr (which has helped in other similar situations), but not in this case.

This is with Python 3.6.3, PyQt5 5.9.2, Mesa 17.2.4, Qt5 5.8.0.

Any suggestions how to further debug this?

I think this was fixed in 3.2.6, please update.

Just tried, still seeing the same issue with Spyder 3.2.6.

The error message is slightly more informative (maybe) when using swr:

$ export GALLIUM_DRIVER=swr
$ spyder3
SWR detected AVX
[57950:57994:0112/103246:ERROR:gl_surface_qt.cpp(251)] glXCreatePbuffer failed.
[58019:58019:0100/000000:ERROR:broker_posix.cc(41)] Invalid node channel message
Segmentation fault

$ unset GALLIUM_DRIVER
$ spyder3
[58066:58108:0112/103304:ERROR:gl_surface_qt.cpp(251)] glXCreatePbuffer failed.
Segmentation fault

I don't think we can do anything about it in Spyder. This seems a problem with Qt. El 12/01/18 a las 06:54, Kenneth Hoste escribió:

@ccordoba12 Any suggestions on how to debug it?

[ccordoba12]

Using the Intel driver should work, I guess. Sorry, I'm not expert on OpenGL.
