Hardware :: New Triple Monitor Desktop - What Graphics Card Required
Jan 5, 2011
What graphics card will support (without too much fiddling) three 24" displays? I just got rid of my mac and am now going to get a linux desktop. I am not sure what distro yet, probably fedora although I am thinking about arch. I have some experience in linux, although nearly none when it comes to hardware configurations. I have two 24" BenQ monitors (DVI and HDMI inputs) and will buy a third 24" display with the pc.
Now I have been looking at some forums about triple monitor setups, but they are almost all about troubleshooting existing hardware compatibility issues. I guess I am at an advantage since I haven't bough any hardware yet, so here is my question. What graphics card would you buy to support 3 24" displays together (meaning that I want to be able to drag windows from one display to the next). I was looking at the ATI HD 5770 and some mention of the eyefinity stuff.

This is a triple-monitor setup with two video cards, where the mouse pointer gets "stuck" if it tries to cross from one video card to the next one. It worked correctly in openSUSE 11.2 and doesn't work in openSUSE 11.3 with the same xorg.conf. This is a 64-bit openSUSE 11.3 with xorg 7.5-11.3 (the openSUSE prepackaged version). I've already tried NVidia drivers 256.53-16.1 (the openSUSE NVidia repository version) and 260.19.12 (the latest off of the NVidia website).
This is the same xorg.conf that I used successfully in openSUSE 11.2. I tried a new automatically generated xorg.conf using nvidia-settings and it had the same problem. This forum won't let me upload the relevant files, but here: [URL] is a tar-ball with my xorg.conf, Xorg.*.log, /var/log/messages, and the NVidia debugging output.

I have been trying to enable compiz on my fedora 14, but when i enable the desktop effects the graphics just crashes and fedora freezes. When i type lspci -nnk | grep VGA for the graphics card i get:
I made alot of research on how to get Intel graphics work on Fedora, but couldnt find any solution
Same problem I had with Fedora Core 12 and 13.

the only way to get multiple monitors AND compositing (Compiz) on Linux is to use a single graphics card that can drive both (or in my case all three) screens. I bought a Radeon 5750 specifically because it claims to able to drive 3 monitors. I can plug in 3 monitors (2 DVI, 1 HDMI) and the Catalyst Control Center shows all 3, but only 2 can be enabled at a time.
The exact message is:
The current settings cannot be applied. Possible issues may include:
- Display(s) cannot be enabled.
- Setting(s) cannot be applied due to insufficient video memory.
So I'm going to assume that either the 5750 doesn't support 3 monitors, OR, more likely, ATI couldn't be bothered to add that support to their Linux drivers. So this is a multipart question:
First, can anyone suggest a PCI Express Graphics card that can run 3 screens on linux without tremendous pain? I'm looking for something where you install the driver and all three screens "just work". Does such a card exist? Second, if you have a 5750, have you been able to get it to do 3 monitors? I'm running Ubuntu 10.04 at the moment. UPDATE: I got my active adapter in the mail today (it's DisplayPort to DVI) and so far things seem to be better. I can run my third screen, drag things seamlessly between them, and I am also running compiz. The adapter I'm using is a "B087B-005B" made by "Accell", UPC is "826388106239".
There's still a couple "annoyances" that need worked out though: The left most screen is always the primary monitor. Which means the "gnome bar" (is that what you call the applications-places-system menu?) is always on the left most screen. It also means that new dialogue boxes always opened centred on the left screen, which is counter intuitive. Especially if you're using a program like GIMP and the text editor or color picker pops up on the left. Does anyone know of a way to change it so that new windows always pop up on the center screen?

i have a fairly outmoded system:
mb gigabyte ga--m57sli-s4
cpu athlon 3800
memory corsair ddr2 xms 2gb
graphics nvidia gforce 8500gt
hdd western digital 400gb sata
monitor hp lcd hp1740
the screen plays up sometimes. it gets a yellow line down one side. it's the office type 4:3 aspect monitor which seem to be getting rarer. if i switch to a widescreen 16:9 format, would i need a new graphics card?
i don't play games. but sometimes there'll be stuttering when i'm watching a videos video. whether this is the screen or something else i don't know.

I'm using an Intel Q45 graphic card, VGA and HDMI. I have two monitors and both work with Win7, splitting nicely. However in Suse it doesn't find the second monitor, the one on the HDMI port. However Suse does find that there is a HDMI port it could use. It's just not set up to have a screen attached to it.Xinerama won't work. I tried it despite the fact that it shouldn't I have tried numerous xorg.conf setting according to a number of sites that were very helpful and very thorough. I tried to modify their advice but it simply didn't work out for me.It seems like the screen is simply not acknowledged within the system for some reason. I'm running OpenSUSE 11.2 with KDE4.4, factory and my other systems pick up the screen without a hitch. My home system did the same with a HDMI connection so if anyone can point me in the right direction or even better

the solution of my monitor is much to small. So I tried to find out, where I can change the settings of my graphic card and monitor. Unfortunately opensuse only gives me the possibility to change it up to 600x800, which is by far too small. So I thought maybe I need to install a driver... so... there I am ... having question marks around my head and wondering how to install a graphics card driver on my opensuse 11.3.???
And where to find the right ones?
My graphic card is a Matrox Mystique (no 220 or anything else!!). I checked the website of Matrix to find my drivers, but it tells me that there is no driver planned for linux. Matrox Graphics - Support - Latest Matrox drivers for legacy products But I guess I am not the only person in the world who uses this graphic card on linux, so there must be a way to make it work!!

I'm planning my next desktop build (currently only have a laptop that is falling apart), and one of the features I'm really looking forward to is multiple monitors. I'm thinking a 1920x1200 center monitor and two 1600x1200 on either side, but I'm not decided just yet. I don't know if I really need that resolution.
I have a few specific questions though. The only time I've ever messed with multiple monitors is way back when I had Windows, so I'm not sure what to expect on Ubuntu.
1: What is the best Graphics card brand/series to use? I've seen that ATI has more powerful hardware than nVidia for the same price range, but nVidia seems to support Linux better. I'm using an ATI card in my laptop now and have never had any problems with it (with either open source or proprietary drives, other than open source drivers didn't do well with 3d). I would also like these GPUs to be running F@H while I'm away, so GFLOPS is just important as gaming performance.
2: Since I want to use 3 monitors, I assume I should get 3 of the same graphics card or a card with 3 identical outputs (do those exist?).
Or can this be done some other way. For example, a more powerful card for the center monitor, and less powerful cards for the other two. Do those need to be the same brand, or could I use, for example, ATI and nVidia cards on the same desktop simultaneously?
3: Is it possible to have a virtual console on one monitor with a desktop on the other two, or do I need to set up a terminal on the desktop to use that monitor?
4: How can I run fullscreen SDL games with multiple monitors? Will it only show on one screen or stretch across them all? Is it possible to have a fullscreen game running on one monitor with the desktop visible on the others? How would the mouse focus work with that? Or does it just all depend on how I setup the monitors?

I know there are many threads on similar issues but I can't find anything that will work. Not sure if I need drivers or what to do - I feel really stupid as I should be able to get this right but I am at a brick wall. Basically I have a 20inch monitor hooked up to the on-board graphics card and cannot get higher resolution than 900 x 600. It should be at 1280 by 1240. This is a brand new install with the latest Ubuntu 10. Under monitor preferences its says 'unknown' for monitor type and I don't have any driver disk for this screen but never needed one previously.

I actually do have a GeForce4 MX 460 in this pc. I have a 7950gt in a different pc. Oops. I guess the MX 460 cant do 1600x1200 on the dvi output but somehow it can do it on the vga output? I guess I could just use a vga connection instead of the dvi connection.
The problem I'm having is that my LCD monitor (acer AL2021) can't be used at it's native resolution of 1600x1200. This is probably because my GeForce 7950gt graphics card is not being recognized. Xorg seems to think my card is a GeForce4 M 460. (It's not, really!) I'm using Ubuntu 10.04 LTS.
Here's what I've been doing for the last few hours:
This didn't work. 1600x1200 is still not listed.

I'm going to be building a new desktop computer and I'm trying to decide between either an ati or nvidia graphics card. I've previously only used integrated intel graphics in my laptop and I've never had any problems. However, from looking at the forums it looks like neither ati nor nvidia will be quite as smooth. What's the current consensus for ease of use?

I have a Sapphire HD4850 X2 1G GDDR3 PCI-E graphis card, and presently I ruin a Windows 7 OS, but am moving to Ubuntu GUI Desktop, and was wandering where I could get Linux drivers for this card (and they are NOT available from the Sapphire site), or how I could get Windows drivers to work with this card, I do have 4 monitors using this card so I need the drivers and ability to use 4 monitors.

I have recently upgraded to Lucid with a clean install. I have two NVIDIA GeForce 7300GT cards with 3 21" monitors connected to them (two to card 1, 1 to card 2 although sometimes I plug in my projector so its 2 to both).I previously had Karmic installed and was able to use all three (or four) monitors without any problems. Now, however, Nvidia-settings only recognizes the one GPU. It will only recognize one or the other. If I edit xorg.conf so that Screen0 is on PCI:3 instead of PCI:1 (where my two cards are located) It will switch over to that GPU, but I can not get both to work together at the same time.
I have tried using my old xorg.conf but it does not work. I've tried editing the current xorg to have one monitor running off of each card and it will not work.

I have a Gigabyte GA-MA74GM-S2 motherboard with integrated graphics that shows up on lspci as an ATI Radeon 2100. I also bought a PCI-Express Nvidia graphics card so I could use the VDPAU feature on Linux (plays H.264 in hardware). The BIOS has three settings about which display to initialize first:
Integrated graphics
PCI graphics
PCI-Express graphics (PEG)
I set the BIOS on PEG, but
I cannot get anything, not even a splash screen or POST messages, to emerge from the PCI-Express graphics card. (I'm using a DVI connector; the card also has an HDMI output.)I cannot get the kernel lspci to see the graphics card; the only VGA controller it acknowledges is the integrated one.Running dmidecode acknowledges the existence of an x16 PCI Express slot, and it says
Current usage: Unknown
There is an additional BIOS setting called "Internal Graphics Mode" which is normally set to "Auto" which means it is supposed to prefer a PCI Express VGA card. I set it to "Disabled" which now means I'm getting no output at all. I will soon be learning how to do a BIOS reset!
Other information: The PCI-E card is a MSI N210-MD512H GeForce 210. This is a fanless card. Although there are no fans to see turning, the heat sink on the PCI-E card is definitely getting hot, so the card is getting some sort of power.It gets all its power from the PCI-E slot; there is no external power connector.The BIOS is an AMI Award BIOS.how can I make the PCI Express graphics card visible to Ubuntu?

I have some very strange issues with my tripple monitor setup on debian wheezy. I have acer aspire V3 laptop with i915 Intel (Intel® HD Graphics 4000) as part of i3 and nvidia GT 740M which I never managed to get working with or without optimus to any degree whatsoever. What I want is a reliably working triple monitro setup. I have 2 additional DELL u2412m monitors which I did manage to get to work on few occasions by more or less randomly turning stuff on and off via lxrand and KDE systemsettings (so I do knwo for a fact that tripple monitor setup works). Arandr doesn't work, and executing xrandr from cmd doesn't work. I can relatively easily get the 2 monitors to mirror each other, but to get them to work separately is extremy difficult. It's always the same error but the well known crt. For example:
xrandr --output VGA1 --mode 1920x1200 --pos 3840x0 --rotate normal
xrandr: Configure crtc 2 failed
xrandr --output VGA1 --mode 1920x1200 --rotate normal --right-of LVDS1
xrandr: Configure crtc 2 failed
When it did work I copied arandrs script in hopes it would work, but it doesn't. Obviously, here is the issue that the crtc can not be configured so if somoen could tell me why and how to get the damn thign to use a specific crtc it would be awesome. Also, I noticed that when I hit "identify monitors" in KDE systemtools, it would say VGA HDMI for both VGA and HDMI outputs.
Here is xrandr output from when it worked:
Code: Select allScreen 0: minimum 320 x 200, current 5760 x 1200, maximum 8192 x 8192
LVDS1 connected 1920x1080+1920+0 (0x46) normal (normal left inverted right x axis y axis) 382mm x 215mm

I have been using AWN for years, having a startup script to run multiple instances of AWN and position it on each monitor correctly. This has worked fine but today I decided to upgrade the version of AWN. The only problem now being that the new version doesn't support multiple instances of AWN to be open at once.The new version of AWN does have an 'Add dock' button but that's no good as my setup isn't Xinerama so each monitor is it's own workspace, meaning I can't position the dock far left, because far left is the edge of the current monitor.
The ideal solution here would to be able to run multiple instances, as I can force each instance to a monitor with DISPLAY=0:1 etc.If anybody has any ideas on how to have AWN on each of the 3 monitors then please let me know.

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.

I have a GeForce 8400 GS card and I run two monitors. I use Xinerama (don't recall now why but I think XrandR didn't work for me) and nvidia. I would like three monitors now and I see here[URL].... My onboard video is disabled by the mobo if I use a video card [URL]... so it seems I need a new video card.
Should I get another GeForce 8400 GS for $40 from Amazon? I suppose the only other idea would be to get a 3-head card but those seem a lot more expensive.

I just installed Ubuntu 10.10 on my Dell Latitude D430 that I use at work. I have it on my desk docked going to a Dell LCD Monitor. When I go into the monitor set up it says Unknown for the monitor and Laptop for the actual laptop display. Also, I have very low resolutions for the "Unknown" monitor.
I am trying to resolved this issue so that I have better resolutions on the external monitor and then I can try to extend the desktop between 2 screens.
I found something online about adding the intel PPA and I did that, but now what. There is no xorg.conf that I can find for 10.10.

I have just bought 2 monitors to be used as a x3 multi setup and 2 graphics cards the same make and model (ATI Sapphire Radeon HD5450). This all works in Windows 7 but I have just booted into Ubuntu and removed the old nVidia drivers and got the supported driver. The problem is only 2 monitors are detected as it would seem that it's only picking up 1 card.

9.10 Problem with Graphics/3D and other I have a Thinkpad T42, 1.7GHz, 1Gb Ram and a Radeon 7500 Graphics card. Everything that I am having trouble with works just fine in Ubuntu 9.04(except for the sound). There are two problems that I think are linked or really the same. First off, When I turn off Compiz(Compiz works by default) then gnome-system-monitor does not work properly. At least the graphics side of it; the window appears black with random lines running threw it. The same thing will happen to Gnome-do if Compiz is off.
The second problem is getting 3d support to work. I installed and tried to run blender and I got this from the terminal:
[Code]...
Then it ether does not open or the computer locks up completely and I have to force a shutdown. Which ever one it does I do not get my desired results. When trying to do chess in 3D it tells that I have 'No Python OpenGL support'. So I install the python-opengl package from the repositories; the program now just errors on start and I had to uninstall python-opengl to get Chess to work again. I have tried all this with Compiz on and off with the same results. Anyways thats about it, unless somebody knows how to setup the sound so a program won't lock it from other, then thats all I am having trouble with.

i'm trying since ubuntu karmic to set up a xorg.conf for a special purpose. I've a htpc connected to my tv. Intel GMA 4500, DVI->HDMI-cable connected, Lucid Lynx installed. When the machine boots with the TV powered on, everything is perfect. xrandr reports all valid modes on output "DP2". Without the TV powerd on, Lucid starts in the low graphics mode, with the funny zenity-message. So far, i managed to disable all useless outputs (VGA1, HDMI1, DP1, HDMI2), leaving DP2 enabled. I managed this by assigning outputs to monitors and adding Option "Ignore" "True" to the corresponding monitor-sections. My only remaining problem is, that the intel-driver reports no connected monitor on output DP2. The TV is connected, but shut off. Has anyone got a hint to tell the driver to ignore the presence of a monitor?
