Still haven't gotten the dual independent displays working, although I think I'm close. I redid the xorg.conf file like the dualhead.html docs stated, and I seem to have gotten most of the errors out the Xorg.0.log file. Defining a monitor for each of the five outputs and Ignoring them seems have mostly worked. But I still have three cloned displays (VGA, TMDS-1, TMDS-2) even though I thought I shut the VGA off, and setup TDMS-2 RightOf TMDS-1 in the ServerLayout. So the trouble seems to be: - The RightOf statement in the ServerLayout doesn't seem to do anything - The Ignore True for the VGA Monitor seems to be accepted (per the log file) then ignored (the monitor comes up). I'm still getting this in the log file (whole log file and xorg.conf are attached): $ cat /var/log/Xorg.0.log | grep Pipe (II) intel(0): Pipe A is on (II) intel(0): Pipe B is off $ cat /var/log/Xorg.0.log | grep pipe (II) intel(0): 2 display pipes available. (II) intel(0): Display plane A is now enabled and connected to pipe A. (II) intel(0): Display plane B is now disabled and connected to pipe B. (II) intel(0): Output TMDS-1 is connected to pipe A (II) intel(0): Output TMDS-2 is connected to pipe A <======= I think that if they are independent, this should be "B" There are still a few errors, but I'm not sure what these errors mean? $ cat /var/log/Xorg.0.log | grep EE (WW) warning, (EE) error, (NI) not implemented, (??) unknown. (II) Loading extension MIT-SCREEN-SAVER (EE) intel(0): Unable to write to SDVOCTRL_E for SDVOB Slave 0x70. (EE) intel(0): Unable to write to SDVOCTRL_E for SDVOC Slave 0x72. (EE) intel(0): Unable to write to SDVOCTRL_E for SDVOB Slave 0x70. (EE) intel(0): Unable to write to SDVOCTRL_E for SDVOC Slave 0x72. I'm going to try playing around with the Xinerama options, but so far all that's done is break xrandr.
