Upgrading to stretch from a fresh jessie install with 4.5.0-rc2 kernel
installed worked fine. :-)
xfce4 display settings is recognising both monitors but the second (which is
different resolution to the mac screen) still won't come up. But at least the
non-booting problem is solved.
I'm going to mess around with xrandr to try to get dual head working.
Hi Clive, That's great to hear!
Just out of curiosity, does the non-mac monitor work when it's the only one
plugged in? I.e. remove the mac monitor and see what happens.
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
