I'm still stuck but I tried to make some progress on my own. Right now I'm thinking an include is missing or something similar to that. I reinstalled 10.3, changed my /etc/make.conf to: 1 DEVELOPER=yes 2 3 WITH_CTF=1 4 WITH_DEBUG=yes and rebuilt x11 ports (xorg-server, xauth, xinit, xf86-video-vesa, jwm). I still see the same issue but I at least have debugging symbols now. 1) Does objdump verify that ioBase is in fact defined or not? When I do: cd /usr/local/lib/xorg/modules/drivers objdump --dynamic-syms vesa_drv.so I can see ioBase is undefined 122 00000000 D *UND* 00000000 VBEBankSwitch 123 00007c1c g DF .text 0000000c Base _restgpr_30 124 00007b90 g DF .text 0000004c Base _restfpr_14 125 00007bf0 g DF .text 00000038 Base _restgpr_19 126 00000000 D *UND* 00000000 xf86DPMSInit 127 00000000 D *UND* 00000000 miGetDefaultVisualMask 128 00000000 D *UND* 00000000 ioBase 129 00007b1c g DF .text 00000028 Base _savefpr_23 130 00007b2c g DF .text 00000018 Base _savefpr_27 131 00007b58 g DF .text 00000038 Base _savegpr_19 132 00007bc4 g DF .text 00000018 Base _restfpr_27 133 00007c10 g DF .text 00000018 Base _restgpr_27 134 00007cb4 g DF .text 00000024 Base _restgpr_27_x I know a little bit of C but I'm pretty much out of my depth here. I'm guessing that the error message is right and .so really doesn't have ioBase defined or what's calling it needs to know about ioBase but it doesn't. http://www.sourceware.org/binutils/docs/binutils/objdump.html says UND means the symbol is referenced but not defined here. I see it defined in /usr/ports/x11-drivers/xf86-video-vesa/work/xf86-video-vesa-2.3.4/src/vesa.h: 80 typedef struct _VESARec 81 { 82 vbeInfoPtr pVbe; 83 EntityInfoPtr pEnt; 84 CARD16 major, minor; ... 112 Bool accessEnabled; 113 OptionInfoPtr Options; 114 unsigned long ioBase; 115 Bool ModeSetClearScreen; 116 void *shadow; 117 ShadowUpdateProc update; 118 ShadowWindowProc window; 119 } VESARec, *VESAPtr; and vesa.c includes it. 2) How can I see what loads vesa_drv.so get in gdb? I know I can do ldd to see the libraries a binary links to. So that a config can be used to set the driver, I know I won't see vesa_drv.so when I look at xorg: $ ldd /usr/local/bin/Xorg /usr/local/bin/Xorg: libcrypto.so.7 => /lib/libcrypto.so.7 (0x41b3b000) libpciaccess.so.0 => /usr/local/lib/libpciaccess.so.0 (0x41cfd000) libdrm.so.2 => /usr/local/lib/libdrm.so.2 (0x41d17000) libpixman-1.so.0 => /usr/local/lib/libpixman-1.so.0 (0x41d28000) libXfont.so.1 => /usr/local/lib/libXfont.so.1 (0x41fa9000) libXau.so.6 => /usr/local/lib/libXau.so.6 (0x4200e000) libxshmfence.so.1 => /usr/local/lib/libxshmfence.so.1 (0x42022000) libXdmcp.so.6 => /usr/local/lib/libXdmcp.so.6 (0x42035000) librpcsvc.so.5 => /usr/lib/librpcsvc.so.5 (0x4204c000) libm.so.5 => /lib/libm.so.5 (0x42065000) libc.so.7 => /lib/libc.so.7 (0x4209b000) libthr.so.3 => /lib/libthr.so.3 (0x42234000) libfreetype.so.6 => /usr/local/lib/libfreetype.so.6 (0x4226b000) libz.so.6 => /lib/libz.so.6 (0x42359000) libfontenc.so.1 => /usr/local/lib/libfontenc.so.1 (0x4237d000) libbz2.so.4 => /usr/lib/libbz2.so.4 (0x42396000) I can't do the reverse though and see what loads a library. I installed gdb 7.10. But I don't see how to step into the code that tries to load vesa_drv.so. I basically get one line of code to execute and that's not helpful at all: # gdb710 --tui --args Xorg -conf /root/xorg.conf.new ┌──stubmain.c────────────────────────────────────────────────────────────────────────────────┐ │26 int dix_main(int argc, char *argv[], char *envp[]); │ │27 │ │28 /* │ │29 A default implementation of main, which can be overridden by the DDX │ │30 */ │ │31 int │ │32 main(int argc, char *argv[], char *envp[]) │ │33 { │ │34 return dix_main(argc, argv, envp); │ │35 } │ ┌────────────────────────────────────────────────────────────────────────────────────────────┐ │0x181c518 <main> stwu r1,-32(r1) │ │0x181c51c <main+4> mflr r0 │ │0x181c520 <main+8> stw r31,24(r1) │ │0x181c524 <main+12> stw r0,36(r1) │ │0x181c528 <main+16> mr r31,r1 │ │0x181c52c <main+20> stw r3,8(r31) │ │0x181c530 <main+24> stw r4,12(r31) │ │0x181c534 <main+28> stw r5,16(r31) │ │0x181c538 <main+32> lwz r3,8(r31) │ │0x181c53c <main+36> lwz r4,12(r31) │ │0x181c540 <main+40> lwz r5,16(r31) │ └────────────────────────────────────────────────────────────────────────────────────────────┘ exec No process In: L??

Like the OP said, the radeon driver isn't an option (building x11-drivers/xf86-video-ati says "xf86-video-ati-7.5.0,1 is only for i386 amd64, while you are running powerpc"), so I'm basically left with the vesa driver (or maybe fbdev? which doesn't work either; that one says "Module fbdevhw does not have a fbdevhwModuleData data object"). This laptop has a Radeon 9550 card. In https://github.com/FreeBSDDesktop/freebsd-ports/tree/zeising/xf86-driver-update there's an update of the vesa driver. Can you please try it out?
