Append the kernel parameters within the /etc/yaboot.conf file
A typical yaboot boot entry with the mentioned appended kernel
parameters applied would like like below:
image=/boot/vmlinux-4.5.0-rc2-powerpc64
label=linux
read-only
initrd=/boot/initrd.img-4.5.0-rc2-powerpc64
append="video=DVI-I-2:D"
Just make sure that as always if any changes are made to
/etc/yaboot.conf, you must run the following command afterwards to
actually apply the changes to the bootloader:
sudo ybin -v
Thanks Peter
Progress of sorts and a satisfactory outcome so far:
Appending the line as instructed activated the second screen :-)
although the graphics aren't great - readable but very fuzzy text and a
multicoloured rainbow effect on the desktop background.
However, attaching a VGA monitor with an adaptor gives better graphics
on the second screen (which it still sees as DVI-I-2); I had to remove
the appended line to get the screen activated - and then it just worked.
Although I had "mirror screens" unchecked in xfce settings, it mirrored
the screens but I could achieve a contiguous desktop with AR&R (and
probably xrandr but I was being lazy).
I'm limited to 1024x768 resolution (on the VGA monitor) which is not
great but better than using the DVI monitor.
clive@Pandora:~$ sudo xrandr
Screen 0: minimum 320 x 200, current 2704 x 1050, maximum 4096 x 4096
DVI-I-1 connected primary 1680x1050+1024+0 (normal left inverted right x
axis y axis) 433mm x 270mm
1680x1050 59.88*+
DVI-I-2 connected 1024x768+0+0 (normal left inverted right x axis y
axis) 0mm x 0mm
1024x768 60.00*
800x600 60.32 56.25
848x480 60.00
640x480 59.94
I'll move on to sound now.
