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.
Regards
Clive
