Triple Monitor Xorg Woes

Hi guys! I've got an interesting setup going here and wondering if it's possible to set it up the way I want it. I have 3 monitors. 2 of them are hooked up to my nouveau card and one of them is hooked up to the intel integrated graphics. This is all working well when I have each monitor on it's own xscreen with Xinerama.
My issue is that compositing with Xinerama only seems to work when I have 2 xscreens enabled. What does this mean? This means that if I want to experiment with any of the more mainstream DE's the way they were meant to be I cannot do it without disabling one of my screens.
What I want to know is if there's a way to have 2 xscreens pinned together with Xinerama but have each individual monitor detected as if Xinerama was disabled.
Here are some of my attempts. http://imgur.com/a/Yfycc
The first one is with each monitor on it's own xscreen. The second is an attempt to merge my two nouveau monitors onto the same xscreen. Something interesting to note is that if I disable the intel monitor and xinerama compmletely the two monitors are detected properly (probably due to xrandr being able to detect them)
Sorry if the post was long and incoherent. I'm doing my best to make it clear what I want
I tried a multitude of other things along with the second one (like enabling both monitors in the screen. Setting modes and virtual parameters in a Display Subsection) none of which seemed to work. Maybe I don't know what I'm doing (I most definately don't know what I'm doing)
Here are my assortment of xorg.conf's

http://pastebin.com/gGk4vh4K <-- nvidia 302.07 Xinerama on all 3. Result? Picture 1  compositing bugs
http://pastebin.com/WHDhqDhK <-- nouveau attempt at Xinerama on all 3. Result? Picture 1 no compositing bugs
http://pastebin.com/Wdax3XVY <-- nouveau attempt at 2 screens. Result? Picture 1
Thanks for the help

that will be more then likely referring to a Falcon Tango Monitor Matrix (The 1 over 3 Monitor Matrix) (Quad monitor stand) without the central monitor attached!
you can only get them from the manufacturer as they are custom made stands and run around $440US http://www.tradingcomputers.com/TCarrays.html
MSI do not make stands like that they will just have been illustrating it like that for Marketing just to show how it could be used

  • [SOLVED]Triple Monitors Xorg with AMD&NVIDIA: XRANDR and Xinerama...

    Hello,
    I'm trying to set up a tri monitor setup. Unfortunately I must use 2 cards, one an AMD HD4350 and a PCI Geforce FX200. (Old skool I know)
    Due to the restrictions, I am forced to use the open source drivers (else nvidia glx will clash).
    As I see it, I have 2 solutions available to me:
    1: Use XRANDR to span the displays (this is what I did previous to the introduction of the third monitor and nvidia card to my system)
    I tried to do this, by setting up a second X screen on the NVIDIA card, disabling Xinerama; but after much googling I can't figure out the syntax for panning across 2 screens (X screens) in XRANDR, even tho it's >1.3, which supposedly supports multi card output.
    2:Use Xinerama, sacrificing randr, and composite extensions.
    I also attempted to do this, with some limited success. I could get the NVIDIA screen to be right of the ATI, but I couldn't get 2 independent outputs running on the ATI card, even with "ZapohHeads" appended to one of the device sections for my ATI card.
    Any suggestions to how I can sort this?
    I'm amazed there's not a way to have mixed nvidia/radeon on X11 in 2011.
    Thanks,
    Chris.
    EDIT:
    It turns out the xrandr multi card output is an urban myth.
    I went the Xinerama route, I've pasted my xorg.conf below.

  • Need Xorg config file for dual graphics cards, triple monitors

    Hey guys, I'm having a bit of trouble getting triple monitors working on my system. The two plugged into the graphics card (radeon x300) work fine, but the one plugged into onboard graphics (geforce 6150SE) refuses to appear in xrandr. I figure I need to make a /etc/X11/xorg.conf.d/10-monitor.conf file but I'm confused about how to do it with separate cards. I find the wiki instructions that I can find confusing, as I've never had to deal with xorg files before (has always autoconfigured for me no problems).
    Relevant code:
    [greg@spacebar ~]$ lspci | grep VGA

    I just can't seem to understand how to write the 10-monitor.conf file. I was wondering if anyone could give me a hand?
    Also, the third monitor to be connected via onboard VGA is also 1280x1024 and will be left of the other two.

    Depends on the motherboard. This one allows you to enable the onboard graphics only when no external card is found, or always enable. The PCI-E card initialises first, if that helps.
    EDIT: Also I can confirm that it can run both cards (all three monitors) at the same time by switching to initialise the onboard card first, however that makes some weird stuff happen so I switched it back. And also the nouveau driver is shown in lsmod, and gets detected in the boot message logs.

  • T420 - Triple Monitors/Enable Optimus?

    I have a T420, and am trying to run 3 monitors (2 external + the laptop display).  I am have hooked up one monitor to the VGA and another to the display port on my docking station, and am able to run 2 monitors in any combination.  However it won't let me do 3.
    According to what I read here http://forums.lenovo.com/t5/Options-Accessories/Mini-Dock-Plus-Series-3-with-Triple-Monitors/td-p/57..., I should make sure Optimus is enabled.  How exactly do I do this?  I saw one note regarding the bios, but I didn't see the setting there that referenced Optimus.
    Thanks!

    Which model T420 do you have?

  • Triple monitor: Sapphire HD5670 512MB (*non* eyefinity version)

    Those reading will know that, in order to have up to 3 displays showing content in a single graphics card, if it's an AMD card then you need a certain feature known as EyeFinity.
    In particular, I am talking about tihs card:
    http://www.google.co.uk/products/catalo … CDAQ8wIwAQ
    You will notice in the picture that this one has  DP, but there is another version that has VGA port in its place. I courd not for the life of me find it again, but at the time of buying the concern was CRT usage, so a VGA port was important. I did not know about EyeFinity at the time.
    This guide is for people whe made mistakes like this.
    This is typically the case. With my card in particular, you cannot get triple monitor in Windows, because the drivers prevent it (it is possible in Linux).
    I said prevent.
    If a card has 3 video outputs, each with their own RAMDAC (or none, if its digital-only), then why can you not use all 3 at the same time?
    Typically in such a setup, if it does not have EyeFinity, then the connectors are usually:
    VGA, DVI, HDMI (my card)
    or
    DVI, DVI, VGA (other cards)
    or
    DVI DVI, HDMI
    or
    HDMI, HDMI, DVI
    In other words, all ef these types of card without support for EyeFinity, do not have:
    DisplayPort connector
    This is a rather crude way of getting it to work, but any solution is a selution still.
    Well, here is a simple way I get triple monitor on my card that does not support EyeFinity:
    VGA lcd in the VGA
    DVI lcd in the DVI
    DVI lcd in the HDMI (using HDMI-DVI adapter)
    The HDMI is disconnected via a coupler, before I boot into Linux. I have a script with these commands:
    xrandr --auto --output VGA-0 --mode 1280x1024
    xrandr --auto --output DVI-0 --mode 1280x1024 --right-of VGA-0
    xrandr --auto --output HDMI-0 --mode 1280x1024 --right-of DVI-0
    (run it as a bash script)
    With the HDMI (via HDMI-DVI, then a DVI coupler, then DVI to DVI going to the monitor) disconnected at the coupler, I run this script.
    Of course, this script sets triple monitor, but right now only the DVI and VGA are hooked up.
    Once it has done, I have dual monitor.
    Then, connect at the coupler (or "gender changer") on the HDMI output. Now all 3 displays are connected, but you still have dual monitor.
    Run the above commands again, and you will see triple monitor.
    Now that you have solved the problem of getting tri-monitor in X, if you look at your TTYs you will notice that only one of the screens is showing. In X (usually terminal 7 or 8), simply disconnect the HDMI at the coupler for a few seconds, then reconnect it.
    Now you to your TTY (Ctrl-Alt-F{1-6}), and it will show text on all 3 screens (albeit duplicated).
    Thoughts,
    I am not sure as to why this is possible to do. I see it as "tricking" the other incapable hardware into outputting on 3 displays, but it seems penfectly functional.
    My guess is that this actually is an EyeFinity card, in the sense that it is the same base an which other cards (with DP, and thus, EyeFinity) are built, but that this particular card can be used in the same way, to get triple monitor.
    Either that, or this is a "bug" in X11/XrandR (if it is a bug, please do not fix it, I like my triple monitors, I call it a feature).
    I know that this certainly works in Xubuntu too, I tried it on a Live CD.
    I tried removing the graphics card and trying this on the intergrated graphics (HD 4290/4250 I think), which also has the same 3 outputs, but the hardwas itself actually enforces a maximum of 2 monitors. If you have DVI and HDMI hooked up, it defaults to HDMI, but masquerades as DVI (where the drivers are concerned). You could use this hack, but then it would still not work because the hardware itself, not the driver softawre, is enforcing it.
    The board is: ASUS M4a89GTD PRO

    Hello,
    i get the same messages without any problems for my intel card.
    You can read more about it in this thread:
    http://forums.gentoo.org/viewtopic-t-85 … ec66f93bf2
    There are a fair amount of people who have posted their /proc/mtrr there, you can compare yours to them.
    In the end they come to the conclusion, that uncachable entries are not a problem, for the most systems.
    However uncachable regions of 1024MB seem to be too large.
    On my mtrr the biggest uncachable entry is 64MB.
    So you might get improvement from solving this.

  • T410 triple monitor capability??

    Hi all,
    I currently use my T410 (w/ NVS3100MS optimus tech) with a LCD via DisplayPort.
    I have another monitor at home with RGB connector.
    I've tried connecting 2 external monitors to have a triple monitor but it did not work.
    I went through the web and looks like for any T410 model, to make a triple monitor i have to have a mini dock.
    Is that the only option??
    Hope anyone knows about this issue. Thanks a lot

    If you had the Tx20 series you would be able to do it without a dock.

  • Triple Monitor on T500 with RC and beta drivers...

    Hello all I was running a beta driver from the beta Lenovo website and was able to run triple monitors.
    Now with the RTM I cannot...
    I was hoping that someone might have the old version of the beta drivers that Lenovo had on the beta site last year aroung May/June...
    This was running without any extra hardware, it allowed windows to "see" both display drivers and allow them to be used.
    If someone want I can send you a pic as proof, but could you please send me the old drivers for the "switchable graphics" ( I think that was the thing.)
    This is a laptop T500 w the ATI 3650 HD and the intel express graphics card built in.
    Thanks in advance.

    What display are you using? Are you using a direct HDMI connection or are you using an adapter?

  • MacPro3,1 triple monitor setup

    Hi there!
    I'm looking to expand my Apple 30" monitor setup with two (very cheap but highly acclaimed) Dell UltraSharp™ U2311H monitors. However, I'm unsure if I do or do not need an additional video card and if so, which one. I have an NVIDIA GeForce 8800 GT with (I think) two DVI-I Dual Link ports. I've read that there are DVI-splitters, but I have been unable to find any conclusive information.
    Does anyone know how I can do this?
    Friendly greetings, D, Amsterdam.

    Hi Grant!
    Thanks for your help earlier ;-)
    I hope you might be able to shed some light on a little problem I have with my triple monitor setup. I bought the following items:
    Two Dell Professional P2411H 61cm (24") LED monitors.
    Two MiniDisplayPort to DVI adapters.
    I've took your advice on the card and also got one ATI RADEON HD 5770 1GB-ZML card.
    The monitors, in combination with the adapters and the card ... it all works, but there's one limitation I believe shouldn't be there.
    The problem is this: either the hardware or software is only allowing me to connect two displays in total. If I connect all three displays, only the Dell monitors are able to connect. If I disconnect one Dell monitor, the Apple 30" display goes live. So, whatever in whatever combination or order I try to connect the displays, only two screens are connecting simultaneously.
    Do you, or does someone else know how to fix this? Would be great to fix this soon and become the pixonaut of my own digitale cockpit!

  • Triple Monitor Display for Laptops

    Im looking for a triple monitor bracket like the one MSI uses in their advertisement for the 4 monitor Matrix display.. Laptop in Middle, monitor on left and right, and one up high. Any help, links, advice would be great.
    Thanks,
    Brett
    MSI GT70-20D Stock the one with the 24gb of ram.. Etc etc

    that will be more then likely referring to a Falcon Tango Monitor Matrix (The 1 over 3 Monitor Matrix) (Quad monitor stand) without the central monitor attached!
    you can only get them from the manufacturer as they are custom made stands and run around $440US http://www.tradingcomputers.com/TCarrays.html
    MSI do not make stands like that they will just have been illustrating it like that for Marketing just to show how it could be used

    I have a similar issue.  I currently have a triple monitor setup, a 1920x1080 + the laptop at 1920x1080 +  another on 1600 x 900.  this works fine.  When I swap out the 1600x900 for another monitor at 1920x1080, i get the same error.  I can get any combination of 2 monitors working, and I can get all 3 working if the 3rd is at a reduced resolution (1400x900), but at full resolution i just get the error.  The same setup works fine in windows at 1920x1080.

    Yes, it works.

  • Linux 3.11 breaks triple monitor support on intel graphics

    I just ran pacman -Syu, observed linux (3.10.10-1 -> 3.11.1-1), and found that I can no longer use more than 2 monitors simultaneously. When I try to configure 3 or 4 monitors with xrandr or arandr, I get an error message like "xrandr: configure crtc 2 failed".
    When I boot with linux-lts 3.10.12, it works reliably again.
    I have Intel HD Graphics 4000 on a i5-3320M CPU for a Thinkpad T530 with a ThinkPad Mini Dock Series 3.
    I have 4 monitors: internal laptop screen, DVI, DisplayPort, and a USB DisplayLink. With linux 3.10, all 4 can work simultaneously. With linux 3.11, any 2 of them can work simultaneously.

    My symptoms seem similar to Unable to configure 3 display multihead / X fails to start with 3 displays connected, although that was reported on linux 3.4.

    Googling around, I found a few more people with what looks like the same problem commenting at the bottom of wrpll sharing not implemented (3x HDMI/DVI screens).
    I have Intel graphics card and it supports triple head setup very well. ... I updated kernel to 3.11.1 after it appeared in Archlinux's repo and one of screens stopped working. I tried to fix it with xrandr but I got only "xrandr: Configure crtc failed" errors and these in Xorg.0.log:
    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.
    But apparently it's not the correct bug since someone said "if triple display worked and regressed in recent kernels then you have a different bug."
    I think I should report this somewhere, but I'm not sure I understand exactly where (linux or xorg or arch?)

  • Widescreen monitor + xorg

    Hi, i have a samsung 940w monitor (widescreen suports up to 1440x900 rez) and im working on 1920x1440, sometimes at 1600x1200. I downloaded 915resolutions but i'd cant get the 1440 900 rez works. Actually i have in the grub module vga=775 ( i dunno the code for 1440 900 if someone know it post it ) and dunno if it has something that to see.
    Also I have another problem (probably it is because of it that I cant get the wished resolution) I dont have xorg.conf, due hwd isnt avaible for 64bits architecture, i'd cant get the xorg.conf, im running the arch64 with xfce across xinitrc and i guess there's the problem, any suggestions ?

    Use nvidia-xconfig or ati-config (the ATI command might be slightly different.. tab complete to find out; been a while since I had an ATI card) to generate your xorg.conf. I don't know the answer to your resolution problem. Your post seems quite hastily written, and as such is unlikely to attract an answer.. perhaps you should explain things a bit more clearly.

  • Triple monitor with intel and SenseVision Club 3d usb to hdmi adapter

    Hi,
    I have an all in one machine with a single intel VGA:
    00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09)
    I also have an external monitor which works fine. I would like to use a third monitor through the SenseVision Club 3d usb to hdmi adapter (Chipset: DL-195).
    http://www.club-3d.com/index.php/produc … apter.html
    I'm using the udlfb module with the option: fb_defio=1
    The monitor attached to the usb to hdmi adapter turns green when the machine starts.
    The problem is that I'm able to use only one adapter at the time. So I can use the integrated monitor and the external one attached to the intel VGA or the monitor attached to the usb to hdmi adapter but not all of them together.
    Here is my xorg.conf:
    Section "Device"
    Identifier "intel"
    Driver "intel"
    # BusID "PCI:0:2:0"
    EndSection
    Section "Device"
    Identifier "dl1"

    # BusID "PCI:0:3:0"
    Option "fbdev" "/dev/fb1"
    EndSection
    Section "Monitor"

    Section "Screen"

    Section "Screen"
    Identifier "screen1"
    Device "intel"
    Monitor "monitor1"
    #DefaultDepth 16
    DefaultDepth 24
    EndSection
    Section "Screen"
    Identifier "screen2"
    Device "intel"
    Monitor "monitor2"
    #DefaultDepth 16
    DefaultDepth 24
    EndSection
    Section "ServerLayout"
    Identifier "multihead"
    Screen 0 "screen0" 0 0
    Screen 1 "screen0" LeftOf "screen1"
    Screen 2 "screen1" LeftOf "screen2"
    Option "Xinerama" "on"
    EndSection
    Switching the screen0 and screen1 positions in the xorg.conf makes work the intel vga. The current configuration enables only the usb monitor. The screen2 is discarded by the xorg stating that none monitor is attached to the device.
    I also tried to tinker with the BusID values. Specifying BusID "USB" makes the xorg crash.
    Is it possible at all to use three monitors at the time with the current state of art? Any success story with this setting?
    Could you please share your working xorg.conf if you have any?
    Any suggestion?
    Thank you very much.

    Apparently yes,
    According to the thread:
    To restore to the old behaviour, put this in your ~/.drirc:
    <driconf>
      <device screen="0" driver="i915">
        <application name="Default">
          <option name="vblank_mode" value="0" />
        </application>
      </device>
    </driconf>
    But I don't come back to the same perfs as before (tested with eternal lands).
    I noticed that in my /var/log/Xorg.0.log:
    (WW) intel(0): Register 0x61200 (PP_STATUS) changed from 0xc0000008 to 0xd0000009

    (WW) intel(0): PIPEBSTAT after: status: VBLANK_INT_ENABLE
    There seem to be some problem with mtrr
    I found this problem which seems related but I only have 2GB of memory

    That's strange.  Here's my config if you can use it for anything.  I don't have that problem, but I also have all NVIDIA boards.  Sorry I was late getting this up.

    Hope it is helpful.   The config works with Xinerama true or false, and definitely doesn't clone any displays.  But you could easily have something else going on that I don't know about.  I'm normally pretty good at configuring my weird hardware, not so much at configuring others.
