Looking at the core dump data, I see that pDRIPriv is null, which is plausible if one looks at the DRI_SCREEN_PRIV macro. I am therefore trying to wrap all the pDRIPriv->... manipulations inside a "if (pDRIProv)" clause.
I also discovered an upstream bug with the same backtrace (and a similar fix reported working) although they talk about dual heads. I have just a simple laptop screen. https://bugs.freedesktop.org/show_bug.cgi?id=8537 -- xorg segfaults in FontFileCompleteXLFD https://launchpad.net/bugs/60288 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
