Description Jasper Lievisse Adriaanse 2010-10-02 02:26:23 UTC

As explained in this bugreport at Clutter (http://bugzilla.clutter-project.org/show_bug.cgi?id=2345), every application linking against clutter-glx-1.0 seg. faults upon execution.

Here is the full backtrace of one of the Clutter example programs, which indicates an issue with Mesa/GLX/DRI:

Any help is much appreciated.

Comment 1 Ian Romanick 2011-02-07 13:41:03 UTC

Is 7.6 the actual Mesa version?  What is the output of "glxinfo | grep '^OpenGL [vr]e'"?  There should be 3 lines of output, like:

OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile GEM 20100330 DEVELOPMENT 
OpenGL version string: 2.1 Mesa 7.9

I'm changing the component since the crash occurs in i915 driver code.

Comment 2 Jasper Lievisse Adriaanse 2011-02-09 07:25:55 UTC

Hi,

the output from glxinfo:
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) 945GM GEM 20100328 2010Q1 x86/MMX/SSE2
OpenGL version string: 1.4 Mesa 7.8.2

I've since updated my machine to Mesa 7.8, though the crash is still there.

Comment 3 Ian Romanick 2011-02-09 11:30:23 UTC

(In reply to comment #2)

> I've since updated my machine to Mesa 7.8, though the crash is still there.

7.8 is pretty old, and it is no longer actively supported by the Mesa team.  Could you try either 7.9.1 or 7.10?

Comment 4 Jasper Lievisse Adriaanse 2011-04-26 04:45:29 UTC

FWIW, this happens still with the latest clutter (1.6.4), exact same issue.

Haven't been able to try this on newer Mesa versions yet.

Comment 5 Jasper Lievisse Adriaanse 2014-09-01 06:47:55 UTC

A lot has changed in the past 4 years, and this now works correctly. So I'll go ahead and mark this ticket as resolved.
