(in my case this is the Intel D945GCLF motherboard including Atom processor)<o:p></o:p> <o:p> </o:p> I’ve been trying to get to the point of using the latest Intel video driver support for X so I built a 2.6.28-rc8 kernel (for the dri.ko and i915.ko) and I followed the majority of:<o:p></o:p> <o:p> </o:p> <a href="http://ubuntuforums.org/showthread.php?t=890843">http://ubuntuforums.org/showthread.php?t=890843</a><o:p></o:p> <o:p> </o:p> which itself basically uses the script given on:<o:p></o:p> <o:p> </o:p> <a href="http://wiki.x.org/wiki/Development/git">http://wiki.x.org/wiki/Development/git</a><o:p></o:p> <o:p> </o:p> to bring all the xserver, app side drm, hardware drivers and <st1:City w:st="on"><st1:place w:st="on">Mesa</st1:place></st1:City> up to the latest.<o:p></o:p> <o:p> </o:p> But when I try to do something as simple as running the latest glxgears (that is the copy that is built amongst everything else in mesa/progs/xdemos) then I find that it just aborts without producing output, the window border appears but then it crashes with a SIG_ABORT. <o:p></o:p> <o:p> </o:p> When I look at this in DDD/GDB the problem occurs in this context:<o:p></o:p> <o:p> </o:p> #0 0xb80d2430 in __kernel_vsyscall ()<o:p></o:p> #1 0xb7f17085 in raise () from /lib/tls/i686/cmov/libc.so.6<o:p></o:p> #2 0xb7f18a01 in abort () from /lib/tls/i686/cmov/libc.so.6<o:p></o:p> #3 0xb7b5d25f in i915_emit_invarient_state (intel=0x805fdc8) at i915_vtbl.c:230<o:p></o:p> #4 0xb7b5d4bc in i915_emit_state (intel=0x805fdc8) at i915_vtbl.c:368<o:p></o:p> #5 0xb7b72f5c in intelRenderStart (ctx=0x805fdc8) at intel_tris.c:1094<o:p></o:p> #6 0xb7c27889 in run_render (ctx=0x805fdc8, stage=0x80a400c) at tnl/t_vb_render.c:275<o:p></o:p> #7 0xb7c1ecd3 in _tnl_run_pipeline (ctx=0x805fdc8) at tnl/t_pipeline.c:158<o:p></o:p> #8 0xb7b73269 in intelRunPipeline (ctx=0x805fdc8) at intel_tris.c:1083<o:p></o:p> #9 0xb7c1f251 in _tnl_draw_prims (ctx=0x805fdc8, arrays=0x8092c10, prim=0x8336da8, nr_prims=2, ib=0x0, min_index=0, max_index=161) at tnl/t_draw.c:402<o:p></o:p> #10 0xb7c1ddd2 in vbo_save_playback_vertex_list (ctx=0x805fdc8, data=0x83369dc) at vbo/vbo_save_draw.c:232<o:p></o:p> #11 0xb7baf26e in execute_list (ctx=0x805fdc8, list=<value optimized out>) at main/dlist.c:5764<o:p></o:p> #12 0xb7bb2665 in _mesa_CallList (list=1) at main/dlist.c:6851<o:p></o:p> #13 0xb7c0c082 in neutral_CallList (i=1) at main/vtxfmt_tmp.h:298<o:p></o:p> #14 0x08049da9 in draw () at glxgears.c:260<o:p></o:p> #15 0x0804a876 in main (argc=2, argv=0xbfeec654) at glxgears.c:312<o:p></o:p> <o:p> </o:p> I *think* I’ve succeeded in getting my system using UXA/DRI2/GEM using the attached xorg.conf.
