I hope this isn't an FAQ.
I am trying to configure a newly acquired Lenovo ThinkCentre M73 which
has the onboard Intel HD4600 video controller with DisplayPort and VGA
outputs. Each output works independently and in combination as an
extended desktop via RandR. However, on the box this one will replace I
have a dual-port Radeon controller that is configured for ZaphodHeads
and I use Xfce for an independent desktop on each monitor. I've adapted
to this work flow and was encouraged by reading of fairly recent support
for ZaphodHeads in the Intel driver. I am running Debian Unstable which
currently has the Intel driver version 2.21.15.
I have tried several configurations from the one I found in the archives
from Chris Wilson:
http://lists.freedesktop.org/archives/intel-gfx/2014-April/044115.html
to a modified version of xorg.conf from my working Radeon system. In
each case the X server aborts and the log file rather clearly states
"no screens found" when I do have screens defined in xorg.conf. At the
moment I am at a loss as repeated searching has turned up no other
clues. Have I hit a bug? What is the most effective way to
troubleshoot this as I've had good success with Xorg for years? I have
attached the latest xorg.conf and the resulting log file as well as the
output from 'xrandr -q'.
Thanks!
- Nate
