The CPU is an Intel 4570S with HD4600 graphics (also supporting 3 heads at the same time). However, I can only get 2 monitors (any 2, but not all 3) working. All monitors are identical 1600x1200 (NEC LCD2070NX). The KDE systemsettings GUI helpfully shows icons for all 3 monitors, but one is always greyed out, and attempting to enable it emits "Failed to set mode: Invalid argument" in Xorg.0.log. Xrandr compians "Configure crtc 2 failed". However, it's clear that the graphics hardware can handle 3 outputs, since it refers to "pipe 0, pipe 1 and pipe 2" in the logs. Google doesn't show anything very helpful, except to warn that in older graphics hardware (definitely not this motherboard) there may be more output connectors than graphics pipelines, and that in the HD4600 there are only 2x PLL, so 2 of the monitors need to be identically clocked (as they indeed are). I'm using the xorg-edgers package, built a couple of days ago from git, and this probleme affects both the latest Ubuntu (Saucy), and Mageia Alpha 4. I'm using a very recent kernel, 3.11.0. Thanks for your help - please let me know if there's anything I can do to assist in debugging/testing. P.S. I originally filed this here, but I think it is really an Xorg bug, rather than an Ubuntu-specific one. https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1215449 Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1215449/comments/2 ------------------------------------------------------------------------ On 2013-08-23T21:07:09+00:00 Daniel-ffwll wrote: Can you please try to set up the 3 pipe configuration using the xrandr tool? This way we can exclude a bug in the kde gui tool. If that doesn't help please boot with drm.debug=0xe added to your kernel cmdline, reproduce the issue (using raw xrandr, no gui tools) and then attach the output of dmesg. Please make sure that dmesg is complete (including early boot logs). If that's not the case please increase the dmesg buffer by adding log_buf_size=4M or so to your kernel bootline.

I think this is going to become quite a popular feature, given that many Linux users are now specifically opting for Intel graphics because it is a more open driver than the alternatives... and Intel is heavily promoting the NUC with a triple-head graphics capability. Alternatively, if this feature isn't planned for a while, can I suggest it would be worth placing a message in Xorg.0.log such as "3rd-monitor support not implemented in this driver yet, see bug 68485", so that others can easily find it without going through hours of debugging and googling.

I have a similar setup and am experiencing the same thing. Downgrading to 3.10 fixed the issue. I'm also happy to help fix this.

This configuration works for me (albeit with slightly imperfect quality on the VGA-connected monitor): Monitor #1 HDMI output -> adapter -> DVI input (1600x1200) Monitor #2 HDMI output -> adapter -> DVI input (1600x1200) Monitor #3 DVI output -> adapter -> VGA input (1600x1200) The 3rd one has to be VGA, or it won't work. Using a direct DVI->DVI cable is problematic. Also, the VGA port isn't autidetected as 1600x1200 capable, but this can be fixed with: xrandr --addmode VGA1 1600x1200 xrandr --output VGA1 --mode 1600x1200 Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1215449/comments/17 ------------------------------------------------------------------------ On 2013-09-25T10:32:09+00:00 Daniel-ffwll wrote: Passive DVI->VGA means you're using the analog side of the DVI connector, which has a different reference clock. So yup, 2x hdmi + 1x VGA is expected to work, it doesn't matter that you have a dvi connector in-between. Of course this only applies to passive conversion cables, for active cables you need to look at the input.
