The complete opposite the Mac mini would not detect the Philips via VGA

But as luck would have it I got it working via DVI about an hour ago.

Added this into yaboot.conf

image=/boot/vmlinux
	label=Linux
	read-only
	initrd=/boot/initrd.img
	append="video=radeonfb:1024x768-16 at 60"

then do a ybin -v
dont need this but I haven't finished yet depth 24 is needed.


also got the Framebuffer to work using a mode line from the Xorg.log file
and a screen bodge

Section "Device"
	Identifier	"Configured Video Device"
	BusID		"PCI:0:16:0"
	Option		"UseFBDev"		"true"
EndSection

Section "Monitor"
	Identifier	"Configured Monitor"
Modeline "1024x768 at 60"   65.00  1024 1048 1184 1344  768 771 777 806 
-hsync -vsync
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Device		"Configured Video Device"
	Monitor		"Configured Monitor"
	Defaultdepth	24
	SubSection "Display"
		Depth	24
		Virtual 1024	768
		Modes		"1024x768 at 60"
	EndSubSection
EndSection

The BusID is reported as PCI:0:10:0 for the video card but I think the 
card is duel head with no connectors on one of the devices so again from 
the log file I used PCI:0:16:0

I wanted to get the thing working using the DVI lead so VGA detect 
problem can wait although I have got a ticket raised with Philips as the 
TV reports it can handle 1920x540 via DCC data on pin 12  so I'm 
guessing the mac tries to use that and the TV just can't so shuts down. 
I think I had two problems: 1 the mac blanking video if it cant detect a 
capable monitor and 2 the TV reporting incorrect modes.

The console is now about 50% over to the right in 1080i video but the 
Xserver using the frame buffer is 1024x768 60Hz. I still need to sort 
out the fb config for the console.

It working but just need to sort out a remote....

Thanks Ron it was your mail that reminded me that log files are the way 
forward its been years since I have had to hack about with frame buffers 
and Xservers and even then if I remember it was James who showed me a 
penguin on the console screen one cold Wednesday night in 
wetherspoons.... I was hooked :)
