Anything else a noob can do?

I remain baffled. The crash appears to be happening deep within your OpenGL driver, so there’s little for me to go on here.

I downgraded mesa from 7.8.2 to 7.7.1 and panda walks again with no tweaks. I’ll just leave it there for now, and file a bug with Gentoo.

nurbs999 · October 23, 2010, 12:47am

thx for your replies, dropdeadsed.
downgrading mesa-libs worked for me, too.
could you send me a link for your gentoo bugreport, please?

Phifo · October 30, 2010, 7:08am

I have the same problem.

Known pipe types:
  glxGraphicsPipe
(all display modules loaded.)
Segmentation fault

I can’t run the first manual example.

I downgrade mesa-libs (but i’m using archlinux not gentoo), but doesn’t help me

Any ideas?

nurbs999 · November 28, 2010, 1:00am

try to set your notify level to debug. that slows down the panda boot and may help.
and could you please give us more info about our system?
kernel-version, mesa-lib version, graphics drivers and version. and which panda version are your running?

Nemesis_13 · November 28, 2010, 1:19am

I guess it’s because you built without JPEG support

[code]
–no-jpeg

[code]

Just for the record: in most, if not all, cases ‘makepanda.py --everything’ is all you need. It will detect missing libraries by itself and append all the --no-* parameters respectively.

Back to the problem. Having the same on my notebook (Archlinux x86_64, Intel Graphics chip).
I’ll try to downgrade the mesa lib and let you know what happens. (Given i success in downgrading, which is a problem on arch…)

Blindly isolated the problem to this code:

  if (!_supports_fbconfig) {
    // We have a good OpenGL context, but it doesn't support the
    // FBConfig interface, so we'll stop there.
    if (glxdisplay_cat.is_debug()) {
      glxdisplay_cat.debug()
        <<" No FBConfig supported; using XVisual only.\n";

      glxdisplay_cat.debug()
        << _fbprops << "\n";

      _context = _temp_context;
      _temp_context = (GLXContext)NULL;

      // By convention, every indirect XVisual that can render to a
      // window can also render to a GLXPixmap.  Direct visuals we're
      // not as sure about.
      _context_has_pixmap = !glXIsDirect(_display, _context);

      // Pbuffers aren't supported at all with the XVisual interface.
      _context_has_pbuffer = false;
    }

So the context never gets initialised if there is no FBConfig support and if notify-level-glxdisplay is not debug. Will check in a fix, but I do wonder why _supports_fbconfig would be false in the case of Mesa.
So this may just be only a part of the problem.

rdb · April 13, 2011, 2:56pm

I think that the whole temp_context hack just doesn’t work for many drivers- I have a hunch that it is causing the fact that these extensions (including the FBConfig one) are being queried incorrectly.
