Xorg log

When no outputs are detected as connected, the server crashes in xf86InitialConfiguration().
In hw/xfree86/modes/xf86Crtc.c:bestModeForAspect(), the return value of the first call to nextEnabledOutput() isn't checked, which leads to a crash in nextAspectMode() because o is config->num_output, and config->output[o] is garbage.
I can easily reproduce this on my laptop with Option "Ignore" in the "LVDS" monitor section.
