I tried booting with the kernel option video=ofonly

and i had no /etc/X11/xorg.conf

This resulted in a segfault of the X11 server, which is attached here.

(clearly, no video is shown)

Interestingly, under this arrangement, the framebuffer seems to think
that it is running at 116Hz, which i don't think the built-in monitor is
actually capable of displaying:

0 root@bagheera:~# fbset

mode "1024x768-116"
    # D: 100.000 MHz, H: 93.985 kHz, V: 116.318 Hz
    geometry 1024 768 1024 768 8
    timings 10000 16 16 16 16 8 8
    rgba 8/0,8/0,8/0,0/0
endmode

0 root@bagheera:~#


Under the regular boot (no kernel video= arg, and an xorg.conf that
forces fbdev), i see this:

0 root@bagheera:~# fbset

mode "1024x768-89"
    # D: 99.197 MHz, H: 72.090 kHz, V: 89.001 Hz
    geometry 1024 768 1024 768 32
    timings 10081 208 48 38 1 96 3
    hsync high
    vsync high
    accel true
    rgba 8/16,8/8,8/0,8/24
endmode

0 root@bagheera:~#


Anything else i should try?
