Problem with XFree and Internal LCD screen

[Laurent de Segur <ldesegur@mac.com>]

Hi,

In my tribulations to get xfree86 to show some graphics, I got scared to
death thinking that I had zapped the LCD monitor.

You will find below my XF86Config-4 that I copied. The machine is an iBook
2001 (dual-usb)

Under xfree86 4.0.1 (woody), I reported earlier that I was getting a message
stating that the monitor couldn't be found. I started experimenting with the
XF86Config  script and simply removed the 'Option "UseFBDev" "true"' from
the Device section. Then I entered startx and I didn't get this message
anymore. X started! So this particular option was causing the error message
I got under 4.0.1 all along.

But even if X started, things didn't work really, my LCD started to flicker
and the screen lighted up with weird patterns like if sand was flooding the
display from the bottom. I couldn't take it, having read horror stories
about monitors getting zapped with wrong params. So I hit the 3 finger
salute and rebooted.

Just after the reboot, the screen was still flickering even when booting
MacOS 9! I went under the monitor cp and changed a couple of time the
resolution, things got okay again after a while. Wow! I came close to call
1-800-MY-APPLE ;-)

Right now, I don't know how I can reboot in terminal mode only because I
know that if I restart with Linux, X will kick on again and do the same. I
don't want to take any risk.

Could someone please let me know the safest way to restart debian and log in
terminal mode without any init scripts trying to start XFree86?

I really appreciate your help.


Laurent
