Using a cinema display



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi folks,

Today I received an Apple 20" Cinema Display to use with my Mac Mini.
It works great in OS X, and on the framebuffer (booting with
"video=ofonly"), but not with X.  I'd like to get both the framebuffer
and X set up correctly.

For the framebuffer, if I boot with

  "video=radeonfb:1680x1050-32@60"

all I get is a blank screen (powersave mode?).  AFAICT all the details
are correct, but something is wrong.

For X, I have a similar problem.  X starts without errors (in the
logs), but the screen turns off and I have to power cycle the system
to use it again.  Has anyone got an example XF86Config-4 I could use?
Currently, I'm using this:

Section "Device"
	Identifier	"Radeon 5962"
	Driver		"ati"
	BusID		"PCI:0:16:0"
	Option		"UseFBDev"		"false"
	Option		"ConnectedMonitor"	"DFP"
EndSection

Section "Monitor"
         Identifier "Apple Cinema Display"
         VendorName "Apple Inc."
         ModelName "Apple Cinema Display 20"
         HorizSync 28-90
         VertRefresh 43-72
         #Option "DPMS"
EndSection

Section "Screen"
         Identifier "Default Screen"
         Device     "Radeon 5962"
         Monitor    "Apple Cinema Display"
         DefaultDepth 24
         SubSection "Display"
                 Depth     24
                 Modes "1680x1050"
         EndSubSection
EndSection

Section "ServerLayout"
	Identifier	"Default Layout"
	Screen		"Default Screen"
	InputDevice	"Generic Keyboard"
	InputDevice	"Configured Mouse"
EndSection

Section "DRI"
	Mode	0666
EndSection


Many thanks,
Roger
