Hi Rick
It seems to be related to the DVI port; DVI-I-1 works but DVI-I-2
doesn't. When I swap the monitors around it's the non-mac one which
works.
$ xrandr
Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 4096 x 4096
DVI-I-1 connected primary 1680x1050+0+0 (normal left inverted right x
axis y axis) 433mm x 270mm
1680x1050 59.88*+
DVI-I-2 connected 1280x1024+0+0 (normal left inverted right x axis y
axis) 338mm x 270mm
1280x1024 60.02*+
1152x864 75.00
1024x768 85.00 75.08 60.00
832x624 74.55
800x600 85.06 75.00 60.32
640x480 85.01 75.00 60.00
720x400 70.08
So xrandr sees both but no signal gets to DVI-I-2
I'm trying out various xrandr settings but I suspect it's something
kernel related. Maybe there's a boot parameter that needs to be passed.

Clive

Hi Clive,
Do you happen to have an xorg.conf? if so, please remove it.
Xorg should probe for your screens and not need an xorg.conf.
It shouldn't need any kernel parameters passed.... But stranger things
have happened!
Please post your xorg.0.log, just curious to see if the edid is read
correctly.
FYI, I tried it with a Quadro FX4500 and a flashed GeForce 7800 and D.H.
seemed to work.
I used a Dell 24" LCD @ 1900x1200 together with an old Philips 20" @
1680x1050 and it worked... For me anyway....
I should have an old GeForce 6600 laying around. I believe you mentioned
this is GPU you have?
If you like, I can try it out when i get a spare moment as well to see
if it works on my end.
It may end up being something specific with the GeForce 6600.
Keep us posted.
Regards,
Peter
