I've come to realize that it has nothing to do with the GPU I use. In each of these scenaries, Xorg segfaults with "Segementation fault: 11 at address 0x8". I initially tried with a radeon HD2600, and that failed: 0x00000008011d5d97 in pci_io_read8 () from /usr/local/lib/libpciaccess.so.0 (gdb) bt #0 0x00000008011d5d97 in pci_io_read8 () from /usr/local/lib/libpciaccess.so.0 #1 0x000000080498cad5 in stdReadMiscOut () from /usr/local/lib/xorg/modules/libvgahw.so #2 0x000000080498ceaa in vgaHWGetIOBase () from /usr/local/lib/xorg/modules/libvgahw.so #3 0x00000008044e2aff in RADEONPreInit () from /usr/local/lib/xorg/modules/drivers/radeon_drv.so #4 0x0000000000471145 in InitOutput () I then tried with the same installation, but booted in vmware player. It attempted to use the vmware video driver, and that failed: 0x00000008011d5e23 in pci_io_write8 () from /usr/local/lib/libpciaccess.so.0 (gdb) bt #0 0x00000008011d5e23 in pci_io_write8 () from /usr/local/lib/libpciaccess.so.0 #1 0x00000008046c3e35 in vgaHWSaveColormap () from /usr/local/lib/xorg/modules/libvgahw.so #2 0x00000008046c43c5 in vgaHWSave () from /usr/local/lib/xorg/modules/libvgahw.so #3 0x00000008042b1892 in VMWAREPreInit () from /usr/local/lib/xorg/modules/drivers/vmware_drv.so #4 0x0000000000471145 in InitOutput () I then swapped the video card with an nvidia 7800, booted off the physical hardware, and that failed (sorry, no backtrace for that one). Others have reported the similar segmentation faults with WITH_NEW_XORG, but none (that I've seen) have gotten it working: http://lists.freebsd.org/pipermail/freebsd-x11/2012-July/012161.html http://lists.freebsd.org/pipermail/freebsd-x11/2012-July/012155.html It would be really great to have a working Xorg again, without having to downgrade... Can anyone comment if this is being looked into? I am now building Xorg with debugging enabled in the hopes of getting information that is more useful. Adam
