Hello,
I have bought a mini-VGA to VGA adapter for my iBook G3 800 MHz 12 inch.
When I use the adapter to connect an external VGA display to my iBook G3:
- in Mac OS X, everything is fine, I can see my desktop both on the iBook
LCD display and on the external VGA display
- in Debian GNU/Linux, I can see my desktop on the iBook LCD display, but I
see nothing but a dark screen on the external VGA display
Here is my /etc/X11/xorg.conf:
I have already modified it in order to support an external VGA display.
