Re: mac68k built-in video (PR#58164)

Hi,

I dunno if it relavent here but I thought I describe how I have a display on 
an external monitor on my Powerbook 160.

First the external display only works in NetBSD -current as I fixed a bug 
relating to video display size and memory (WSFB kernel GENERIC worked without 
the fix).

The Booter only passes the primary display to the kernel in various mv_video* 
paramaters and it was only possibile to attach one display either internal or 
external video, enabling video mirroring resulted in the internal display 
working only.

To enable the external display:

1. Disable video mirroring in the Powerbook display control panel (something 
similar might be required on other macs with video cards).

2. In the monitors control panel in the box with displays marked "1" and "2" 
or more move the menu bar to the "2" or prefered display. and close the 
monitors control panel.

This display now becomes the primary display and its video paramters and 
address and such are passed to the kernel and is used as the kernel display.

I hope this helps.

Best regards,

Nat
