Xorg -configure generates a file, which I slightly modified for dualhead mode. Xorg -config xorg.conf.new receives a sigsegv right after the start, during its initialization. ======= Program received signal SIGSEGV, Segmentation fault. i830_allocate_aperture (pScrn=0x7fe210, name=0x2b71fc1774fb "secondary front buffer", size=<value optimized out>, alignment=65536, flags=0) at i830_memory.c:429 429 i830_memory.c: No such file or directory. in i830_memory.c ======= The same problem was with the previous versions (x11-base/xorg-server-1.3.0.0-r1 + x11-drivers/xf86-video-i810-2.1.0). full gdb backtrace to be attached.

Upstream doesn't want to fix old style Xinerama setups. You'll have to use xrandr to setup your dual head. I'm really sorry about that, but there's nothing else I can do.
