Hardware :: Triple Monitors Xorg With AMD&NVIDIA: XRANDR And Xinerama Not Working?
Mar 24, 2011
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).
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.

Did a new install with a system that worked well on 10, with Xinerama. I have nvidia 9500 GT cards, but I dont think its driver related. Screen 0 is the center Screen 2 is to the right And Screen 3 is to the left.. When Xinerama is disabled things work flawlessly, but not using Xinerama is a killer to me. The nvidia configuration utility generates the following xorg.conf when Xinerama is disabled. It gets the locations right and the mouse moves correctly between screens.

Can anyone help with me configure my dual-screen monitors for rotation? I have xrandr 1.1. Have tried various approaches, nothing takes. I can't even get the xrandr options to show up in KDE's Display control panel.

I would like to adjust Xinerama to place 1 desktop on each of my 2 monitors and not stretch a single over both. With the current set up there is a problem with window placement upon opening new widows or context dialog boxes. I realize that I could adjust placement properties and select window placement with the mouse but this is still lacking in productivity. My monitors are not next to on another so this is more of a problem than it seems.

UPDATE: I can get the wrapping to stop, but it offsets the image between monitors. It's like the center monitor's image was stretched upward, distorting the alignment with the side monitors, rather than just providing additional space at the top. If I switch it so the two side monitors are 120px lower than the center, (as i had it in 9.04) then the wrapping issue occurs again. This is frustrating. I could use some help. (64-bit Ubuntu 10.04)
After lots, and lots, and lots of googling, configuring, experimentation, and even unplugging and replugging, I finally got all 3 monitors working like I had them in 9.04... Or almost. The center monitor is larger than the two side monitors, being 1920x1200 compared to 1920x1080. When I move the mouse pointer on the center monitor, it hits a ceiling and disappears right around that extra 120 pixel area on top, and can be seen at the bottom of the screen.

After working on trying to get my 3 monitors to work with Ubuntu 10.4 and my ATI Radeon HD3200 (IGP) and HD4850 cards, I just had to share the xorg.conf. I am using the default open source drivers that came with 10.4 and I kept KMS enabled (it wouldn't work without it).
Here is my conf:
Code:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "4850-2-Screen"
Screen 1 "4850-1-Screen" RightOf "4850-2-Screen"
Screen 2 "3200-Screen" RightOf "4850-1-Screen"
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
Option "Xinerama" "on"
#OPtion "Clone" "off"

I currently have my monitors set up as an extended desktop using Nividia's Xinerama function. Everything works sweet, except it's acting slow and lags out. It all works out fine when Xinerama is disabled. At the moment, I'm using CentOS with Gnome, but I've tried other distributions with the same outcome. If I can't a fix I'm going back to windblows.
Computer specs:3 monitors
2 Nvidia GTX 275 GFX cards
EVGA 4-way Classified motherboard

On openSUSE 11.1 I was able to configure KDE 4 for 2 monitors with sax2 (although the resolution was bad).On 11.2 neither SAX2 nor KRandR seem to work. The KDE User Guide says that a driver supporting version 1.2 is necessary. However the nvidia driver for eForce FX Go5200 seems to support only version 1.1.Is there a way to use both monitors with SUSE 11.2? I am quite desperate since for my work using only 1 monitor is definitely a handicap.

i have a laptop and i plunged an external monitor into it. I want to obtain a virtual desktop[ I will privede more debugging info below
video card
01:05.0 VGA compatible controller: ATI Technologies Inc RC410 [Radeon Xpress 200M]
Driver:open source radeon driver distribution kubuntu 10.04
I tried this:
xrandr --output LVDS --mode 1280x800 --pos 0x0 --output VGA-0 --mode 1920x1080 --right-of LVDS --pos 1280x0
it resulted this error 1
xrandr: screen cannot be larger than 1920x1920 (desired size 3200x1080)
Googling about this error i found a old post,it could be outfated that sugested editing xorg.conf. I created a xorg.conf using "Xorg -configure" and i modified the screen section to this:
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"

Currently I have a perfect setup of 3 monitors,2 GPUs running under Xinerama. I cannot get desktop effects running at Normal or Extra, when I try to enable either one I get the following message "The Composite extension is not available". Without Xinerama it works along with Compiz. I am running Ubuntu 9.04 x64 with a ATI HD4870 and ATI HD4350 GPU. I have the latest ATI display drivers (set up properly to my knowledge). Here is my xorg.conf file.

I have 3 monitors across 2 video cards, thusly I must use Xinerama (And xserver-xgl for compiz of course, but that's another story and regardless of this issue) in order to combine all three monitors into one large session.
The issue is that, on 10.04 due to an update to xorg which has a regression, moving my mouse across to the left monitor causes it to flicker back and forth between the left and center monitor (While also freezing the rest of the display), and it eventually crashes xorg shortly after. This bug has been reported [URL] and has been open since Ubuntu 10.04 alpha, but perhaps there is some workaround here as this is a make-or-break thing for me. If I can't get this working, it's back to Windows...

I have a dual Monitor Setup, both SXGA LCDs, one rotated left. With kernels and Xservers available from debian making settings appropriate kills X and apparently leaves modesetting and keyboard missconfigured - monitors say: no signal and it is not possible to switch to any VT until sysrq-unraw (alt-print-r) is pressed, which makes the system responding to keyboard, but still leaves the screens blank. Restarting the display manager sets a working mode with both screens showing the same.

I am trying to use three monitors with two video cards on Fedora 13:
$ lspci | grep -i vidia
07:00.0 VGA compatible controller: nVidia Corporation NV41 [Quadro FX 3450/4000 SDI] (rev a2)
0c:02.0 VGA compatible controller: nVidia Corporation NV44A [GeForce 6200] (rev a1)
$
The Quadro dual-card has no problem driving two 19" monitors, but the GeForce will not wake the third 17" monitor from power save mode. The BIOS indicates that the Quadro is the primary card. I am trying to use Xinerama to activate the GeForce. So far I have only seen the GeForce and 17" monitor work if the Quadro is physically removed. In all cases I have been using nouveau. I'll attach my xorg.conf, Xorg.0.log, and smoltprofile.txt. My xorg.conf shows two monitors: monitor0 (19") and monitor1 (17"). monitor0 is actually two identical monitors which the quadro treats as one large monitor.

I'm using a netbook with an intel GPU and a recent intel driver. In my .xinitrc, I have this command: xrandr --output LVDS1 --set "scaling mode" "Full aspect" But that causes a brief black flicker and stalls the login a little bit. I'd like to specify this in my xorg.conf or find some way for this option to be set as Xorg starts. I don't know what the xorg.conf equivalent option is, or even if one exists.

I have been trying my little heart out to get triple monitors setup but I just cant seem to do it. So I have decided that I will quit out on my current video cards and pick up a few new ones and see where this takes me. The cost effective ones seemed to be some 8400s, one would be a PCI-express and one would be on the normal PCI but both are the same GPU. So with this setup would X be able to run all 3 screens with composting so I can run compiz and stuff. And have it one extended x session not 3 separate ones? Specifically I was looking at [URL].

I am setting up a display system that will not have a keyboard/mouse and automatically boots into gnome and starts up firefox to a display page. The page is optimized to a 720p resolution which I can set when we use a TV for the display, but is not an option if we use a monitor. I am trying to find a way to set the resolution to 720p automatically on boot up. I am always using 16x9 displays with a DVI connection (to HDMI on TVs)
I was able to get one monitor working by creating a script and setting it to load in the Startup Applications as shown:
Code:
#!/bin/bash
scnres="1280 720 60"
modeline=$(cvt -v $scnres | grep Modeline)
modeline=${modeline#Modeline }

I currently have 2 GPUs in my system both ATI. The primary is a HD4870 and the secondary is a HD4350.
I have a 24" and a 17" running in twin view from the 4870 but I can't figure out a way to enable my third monitor to display anything at all, I have tried multiple configurations but I end up breaking the xorg every time.
All I simply want to do is keep my twinview on the monitors run by the 4870 but have the third monitor as a separate X session so I can still use compiz. Here is my xorg file, it was generated by aticonfig.
Code:

I attempted to write my own xorg.conf file, but that resulted in the machine booting to single user mode and the xorg startx error log said it could not find any devices.
When I used the xorg.conf.new generated by the "xorg -configure" command, I was able to get it to display as 3 independent screens, but there was overlap on the screens. I.E. if you moved the mouse to the right side of one monitor, it would show on the left side of another screen at the same time.

fresh install of 11.04 on a built system (frankenstein leftovers), 2.something ghz, 1gb ram, a host of drives, and a 64mb nvidia mx440 with svideo out. Boots up, looks pretty, something about unity not finding 3d graphics (fine, i don't really want it, just more fancy gui crap to suck cpu cycles) and runs fairly well. so I think, cool, svideo out, old 52" rear projection....HTPCish. "Lemme get this thing hooked up to the tv, what a great idea" So, I start looking around and find all kinds of wrong posts about not Natty, and not my video card, and I try this n that,and it doesn't work. I'm all about reading the forums, but I can't find the right info for my sitiation, and I'm overwhelmed/irritated.
Long story short, I added some repository ppg something, and then dl'd and installed the "nvidia-current" driver. After a reboot, I fire up the nvidia gui, and it tells me I have no xorg.conf and to run a particular command in terminal to make one. So I did it. and after another reboot, my system just hangs at "ubuntu" with the four (five?) dots. Reboot, recovery, something something something, safe graphics, backup your xorg.conf? yes. reboot and all is ok now. still no nvidia support. Now I'm reading the internet machine about the xorg.conf being old school, and how I have to make a monitor.conf file with config settings. only problem is it tells me to go to x11/xorg.conf.d/whatever. I have no xorg.conf.d directory. So what's the deal? How in the hell do I get the nvidia driver installed (I think I got that), configured (I have no clue), and running (yeah, I just saw a flying pig)?

I am having some real problems with my dual monitor setup in Centos 5.6.I am trying to run 2 individual monitors like span say the whole desktop over 2 monitors say, using the Admin>Display (I think it's that menu, sorry working from MS Windows at the moment).But everytime I set them up perfectly, every time as it requests you do reboot your computer once the changes have been comitted (written to presumably the xorg config file), the whole Window X Server? it crashes.
Any suggestions as to what to do? I am using an Nvidia Gefore 9600 GSO 768Mb RAM graphics card on it, using one DVI monitor and then an old CRT, but surely it should be the software or even the drivers that are causing the problem.I mean I could just put up with having one monitor but it really bugs me, as I prefer to have one screen for my research and one screen for my production work so to speak.Also I am running an AMD processor +4400 to be exact

My Dell Precision Workstation was shipped in 2003 with RH Linux installed (most likely RHEL 4) - though not sure.
At the time, the dual monitors worked by replacing the X86config file with one sent from Dell.
Since, my disk failed and I had to replace the disk and reinstall RH Linux with the shipped disks, RHEL 5.
Now, I can not find X86config; rather, I have been trying to update the Xorg.conf file with no to limited success.
Both monitors are driven off of one Nvidia Quadro FX 1300 videocard. My goal is to get the screen to span both.
Does anyone have a Xorg.conf file that would support this?

I just got a new comp and trying to get a tri-monitor setup working. I have a 460 GTX which has 2 dvi & 1 mini hdmi and only 2 of those will work at a time (2xdvi or 1xdvi 1xhdmi) So while in the Nvidia control panel I select the 2 as separate x-screen but the 3rd wont allow that option. When I activate the Xinerama it doesn't seem to make any difference.
EDIT: Also the only way to get the 3 showing up in the control panel is to set 2 as separate x screen and 1 as twin view...But when I hit apply it says: Failed to set MetaMode (1) 'DFP-0: nvidia-auto-select @1920x1080 +0+0' (Mode 1920x1080, id: 0) on X screen 0.

My Dual G5's psu blew up this weekend, and i refuse to go back to windows, so until i can come up with the $$$ for a new PSU i installed Fedora 10 on an old Dell GX270.
Now, ive got 3 video cards to play with. An Nvidia Geforce4MX, an ancient matrox PCI, and the onboard intel VGA out.
Mind you, ALL of these cards work just fine on their own. All of these will work dual and even tripple monitors in XP. But i hate XP.
Now when following th xinerama tutorial, i took bits and peices from the XORG.conf files of each card to make my own..and ALL I GET on boot is "No Screens Found" so i have to remove matrox card (If plugged in) and reconfigure the X server. otherwise if i dont remove the card i get a blank screen.
Now heres the config Fedora gave me for the working NVidia card (singlehead mind you)
Code:
Now heres the one i came up with for the AGP and Matrox PCI Card:
Code:
Whats interesting is, is when i run the grep command to get the PCI id, it only shows the one card. Same when i run system-config-display, it will only detect one card/one monitor. So that leads me to beleive i have to force Fedora SOMEWHERE before it reads Xorg to detect more than one VGA card.
So right now as i type, i'm running the Nvidia, and the Intel...but the intel is just blank. i checked the log file on Xorg, but see NO intel/Matrox anywhere in the file, which makes me wonder if the system is even seeing it.
I do NOT want to go back to windows...and actually when i get my mac back, i think i'll keep this linux machien chugging on the 2nd LCD channels, just because its been so pleasant to deal with.

I have had it working w/ two monitors plugged into the ATI correctly. and the nVidia monitor blank.

It does show the boot screen and works up until the point you are presented w/ the login screen for ubuntu, then it disappears and the nVidia monitor turns on. Might I have something wrong w/ my xorg.conf or do I need to do something more to get this to work? Currently I'm seeing this error in my Xorg.0.log file, but I'm not sure where to go from here:

I'm trying to get 4 monitors working in Ubuntu 11.04 the way I would like to. I have two Radeon video cards with two monitors connected to each. With proprietary ATI drivers and the Catalyst Control Center I'm able to see all the monitors and Have Multi-Display setups, but they're separated for each video card. I can move items to and from Monitor 1 to Monitor 2, and Monitor 3 to Monitor 4. I'm not able to move windows from 2 to 3 or 4. The two separate display setups have their own set of workspaces too. I've tried enabling xinerama, but when I log back in after a restart the screen is just black and I'm forced to reboot manually. The two separate displays wouldn't be that much of a problem except that my keyboard doesn't seem to work on any application opened on monitors 3 and 4 after I've clicked on something in Monitor 1 or 2.
Below is one of the configs I've been messing around with:
Code:
Section "ServerLayout"
#Screen "amdcccle-Screen[2]-0" 3840 0
#Screen "amdcccle-Screen[1]-1"

2) My Display seems to think I have dual monitors attached permanently.
3) fn + F4 only blacks out screen for a few second.

I've just installed 10.04 on an old system.
Hardware is:
- NVIDIA GeForce 6600 GT video card
- Gigabyte EP35C-DS3R motherboard with 3 gig ram, few TB of hard-drive
- dual monitors, both viewsonic vx2235wm, primary on analog, secondary on digital (but whatever, happy to reverse the order)
On the old setup (8.04) the monitors were set up as twinview, 1680x1050 each, no problems. On the new setup (10.04) my old xorg.conf (see below) doesn't work and nvidia xserver settings refuses to detect my second (digital) monitor at any resolution greater than 640x480.
I've tried messing with xorg.conf to no avail and google doesn't appear to be my friend.
Here's the old xorg.conf file that worked in 8.04 but refuses to even boot under 10.04:
