That segfault looks reminiscent of: [libdrm] commit 08371bc29013370558728dcbeeed6a23ad2f5a70 Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Tue Dec 8 22:35:24 2009 +0000 intel: Clear virtual after failing to mmap_gtt. Don't store the error return in bo_gem->gtt_virtual or else we will attempt to use that as a valid pointer in future mappings. I've pushed some improvements to xf86-video-intel that should prevent this from occurring in the first place. -- <div><div></div><div class="h5">Chris Wilson, Intel Open Source Technology Centre </div></div></blockquote></div> Allright. I tried to compile the latest tag of the xf86-video-intel ( 2.11.0 ) and when I ran the autogen I received the following : "checking for DRM... configure: error: Package requirements (libdrm >= 2.4.16) were not met" Just to let people know that xf86-video-intel WILL NOT compile against libdrm 2.4.16 because the I915_PARAM_HAS_PAGEFLIPPING is not defined in libdrm 2.4.16. I is only introduce in libdrm 2.4.17 The 2.11.0 configure script should require 2.4.17. Compiling with 2.4.17 will lead to this error : drmmode_display.c: In function ‘drmmode_do_pageflip’: drmmode_display.c:1366: warning: implicit declaration of function ‘drmModePageFlip’ drmmode_display.c:1366: warning: nested extern declaration of ‘drmModePageFlip’ drmmode_display.c:1367: error: ‘DRM_MODE_PAGE_FLIP_EVENT’ undeclared (first use in this function) drmmode_display.c:1367: error: (Each undeclared identifier is reported only once drmmode_display.c:1367: error: for each function it appears in.) drmmode_display.c: In function ‘drmmode_pre_init’: drmmode_display.c:1460: error: ‘I915_PARAM_HAS_PAGEFLIPPING’ undeclared (first use in this function) drmmode_display.c:1471: error: ‘drmEventContext’ has no member named ‘page_flip_handler’ I will test with 2.11.0 and if I'm still experiencing issues, I will get the latest git version. Thanks for the help Chris ! -- Phil
