Help with dual monitors

I installed Arch on an old Asus MB, and have spent a couple days trying to get dual monitors working. The board is a P4S8X-X with no onboard video, an AGP slot, and six PCI slots.
First, I tried using an AGP card together with a PCI card with no luck. I tried using two ATI pci video cards, again no good.
So, I downloaded a MB manual and discovered that the PCI slots and the AGP slot are all shared. Quote the manual: "When using PCI cards on shared slots, ensure that the drivers support 'Share IRQ" or that the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI groups, making the system unstable and the card inoperable."
I'm wondering if dual monitors are possible with this board. I have another Asus board with an AGP and three PCI slots apparently not shared.
Couple years ago, I installed dual monitors on my FreeBsd computer, using two cards on an MSI board, with no trouble. What I'm looking for is two independent monitors, each able to run an application. I use the JWM window manager. I haven't posted an xorg.conf file as there have been too many to display.
Any help is appreciated.

Problem solved. I switched motherboards and dual monitors are running.

[SOLVED] Help with dual monitors (second monitor won't wake up)

Hi. I'm trying to set up dual monitors, but I can't seem to get it to work.
I've got an ASUS P8H67-M EVO motherboard, and I'm using the xf86-video-intel driver. I'm using one VGA and one HDMI.

So it looks to me like both displays are being detected. The geometry looks such that one display is on top of the other, but I can change that using an xorg.conf.d config file (e.g. https://wiki.archlinux.org/index.php/Mu … xorg.conf). I also tried using arandr.
The real problem is that the display on HDMI3 just isn't "waking up". The power is on, but it just sits there in sleep mode.
Any help would be great. I might just be missing something simple. Thanks.
Edit: I just saw a short list of window managers near the bottom of the Arch Multihead page (https://wiki.archlinux.org/index.php/Mu … _xorg.conf). I don't see openbox on that list. Does that mean I'm SOL if I want to use openbox with multiple monitors? This page seems to imply that it should work fine with openbox http://magnatecha.com/dual-monitors-wit … nd-xrandr/.

I use XFCE, and when I boot my computer I just run:
xrandr --output DVI-I-1 --auto --output DVI-I-2 --auto --left-of DVI-I-1
I'm assuming if you modify the names appropriately that it'll work too. I have had issues before trying to run dual monitors without taking both outputs off of a single video card (which is what I'm doing now). For example, I had a graphics card with one (VGA) output and a VGA output on my motherboard. But, connecting the graphics card disabled the on-board VGA. So it is possible (I'm not an expert here) that two displays coming off the motherboard may not work for hardware reasons.

Using this xorg.conf file, only my NEC LCD analog monitor could display KDE while the Samsung digital can't.
Any suggestions?

Thanks for your help guys, I'm halfway there.
The second monitor shows the KDE desktop, but it isn't exactly what I expected. Right now, both monitors display at 1024x768 (each) or 2048x768 (total). The larger monitor stretches and distorts the display of 1024x768 to its natural resolution at 1440x900 and it isn't what I wanted. Other than that, the dual desktop setup behaves what I expected to.

Interfacing with dual-monitor machine

Hello all--
I've got a G5 at home with dual monitors on which I run 3D animation software with lots of panels. I'd like to be able to control the G5 from work using a laptop (possibly also connected to an external monitor). Is it possible to display both screens of the desktop using ARDv3 on the laptop? Some users have mentioned they can do this but the size of the remote screens is unsatisfactory. So, again, can you visualize both screens well via the remote computer?
Thanks for any help you can offer.

you can view both screens at once but it will be scaled to fit on the screen you have... so what you see is dependent on the resolution of both client monitors and your admin computer's monitor.
you can also select to view a single monitor of the client computer.
i've never run ARD admin on a computer with 2 monitors so i'm not sure how it handles it but i'm guessing that you can view both monitors on both admin monitors.... it'll probably scale down or up dependent on resolution.

Run screensaver independently with dual monitors

Nope. Can't do it.

Gnome Crashes on Login after messing with dual monitor settings

Gnome displays the sad monitor and has the error message "..something has gone wrong..~" and will force me to log out. I've only started to experience this after messing with dual monitor settings in nvidia. The dual setup(twinview) worked but once I rebooted, I couldn't get it going for awhile.

Extra Notes: I have another desktop session with awesome installed(uninstalled now) and could log into that no problem. Awesome was giving me troubles so I uninstalled it. I have 2 gnome desktop sessions, my regular gnome session(the one that crashes), and the other with no window manager(never crashed on startup).
I installed awesome around the same time as configuring the dual monitor setup.
Thanks.

Update.
The crashes are to be expected now. I'm circumventing the whole thing by logging into my other Gnome session without a window manager, logging out and then logging back into my regular Gnome with Metacity.
I've noticed the tty1 sessions(not sure what's it's called) is strange. Apparently my session runs on tty8 but when I try logging in, it'll crash me and tty7 gives me a blank screen with a blinking underscore. The other tty1s work regularly. Not sure if this has anything to do with it.
Is there a way to just reset the Gnome settings?

Need to launch Organizer Twice to work with Dual Monitors

If I open a project or either Photoshop Elements 10 or PRE10 and then click on Organizer it loads, but sits in the taskbar below. If I hover over it the AERO Windows (Win 7) pops up showing it's loaded. But It will not maximize. This is when I had last used it on a second monitor so I can easily compare before and afters. However, if I right click on it and close it, then reopen it, it launches perfectly in the 2nd monitor. Does this every time. I ussually leave it open all the time now to avoid this but I don't know how sesitive the catalogs are if the system is rebooted for some reason.
I did no specific configuration for dual monitors, Just dragged it over there when I wanted to use it.
Thanks,
Joe..

Hi Joe,
This is a known issue with dual monitors and got to know that Organizer people are tracking it as a bug for now.
Hope this will be fixed soon.
Thanks

[SOLVED] openbox margins with dual monitors

Hi community,
I have stumbled to a nasty problem on my first incursion to dual monitors in openbox.
I'm using xrandr with this command (which works just fine BTW):
xrandr --output LVDS --mode 1280x800 --primary --output VGA-0 --mode 1280x1024_60.00 --gamma 1.0:1.4:0.85 --right-of LVDS
and have set a Virtual screen in xorg.conf of 2560 x 1024 pixels.
But, my laptop monitor only handles 1280x800, while my external LCD monitor has 1280x1024, so there is a virtual area under my laptop screen which i'm not using, but i dont really care about that.
The problem is that when I'm setting screen margins, so that maximized windows will respect the panels in the bottom (tint2), in rc.xml (or by obconf) the margins are applied to the virtual screen and only are practical on the external monitor wich has more pixel height.
I'm really missing some kind of per monitor margin settings in openbox, maybe there is and i haven't found it? It makes me wonder because openbox can maximize windows to a single monitor, even if the whole layout it's treated like a virtual screen, so it has some way of distinguishing between them.
I would appreciate any suggestions, thanks.

TL;DR - I'm not aware of any acceptable solution at the moment.
Basically, what you're having problems with, is the "dead area." It can really be quite a pain in the butt if window managers or other screen aware applications don't anticipate it properly. To my knowledge, Openbox doesn't support margins on a monitor-by-monitor basis. In reality, you shouldn't need to be setting margins anyway. Tint2 should be reporting itself as a taskbar, and Openbox should be respecting that.
I have dead area too, with multiple monitors, and Openbox respects both of the KDE taskbars I have running (one on each monitor). (I use KDE and simply replaced Kwin with Openbox.) This tells me that tint2 should be able to cooperate with Openbox. I remember trying tint2 a while ago, and didn't fine it adequate in a dual monitor environment (it was probably a year ago or so). tint2 would need to be setting the _NET_WM_STRUT_PARTIAL hint, and I'm not sure if it is (or if it's doing it properly). See http://standards.freedesktop.org/wm-spe … #id2507618
Also, I do know that the developer for Openbox recently got a dual monitor setup, and she's been adding additional support for dual monitors a little at a time. Hopefully with 3.5, there will be a lot more support. (Margin support for multiple monitors would be great, because it could be a good utility knife for applications that don't care about multi-monitors setups and don't set the proper hints.)
If you're capable of modifying tint2, my course of action would be to try something that works (like the KDE taskbars) and record the hints being set there. Then compare them with tint2 and try to mirror KDE's setup. (If you're a programming lacking experience with X and related nonsense, I'd be more than willing to offer what guidance I have.)
Also, I developed a panel myself (and got pretty far along) using the PyGTK toolkit... But I can't remember if I solved this problem or not. I'll try to check it out and get back to you. (I got as far as implementing a widget system that includes a task list, system tray, clock, menus... It just isn't polished very well. My original intention was for it to be a more robust PyPanel with dual monitor support.)

Unwanted keyboard shortcut with dual monitors

Problem:
I have a computer setup with dual monitors (desktop extended). When I have a window open, e.g., Microsoft Word 2007, after I type "1" on the keyboard, the Word Window and mouse relocate to the second monitor. When I type "2" the Word window and mouse relocate
to the main monitor. In the word document, 1 and 2 are typed in the document, but pushing the keys still move the window and mouse to the opposing monitor.
I checked the keyboard settings within Windows and found that sticky keys and such are not enabled. The keyboard has no such features to enable. I also checked the display setup in display properties and found nothing that would indicate such a setup. Google
searches return nothing related to my problem.
What I do know:
-The rest of the numbers on the keyboard work fine. Pressing 1 and 2 on the number pad at the far right of the keyboard do not transfer the active window to the second monitor. Those keys work fine.
-The type of window does not matter. Using notepad, word, excel, internet explorer, sticky notes; all of those windows would transfer to the opposing monitor when I push 1 and 2.
Setup:
Windows XP
Dual-Monitor
Wireless Keyboard and mouse

This pertains to StarTech DVI to USB adapters.
There's an icon in your system tray near the clock, either super utility or usb display device. Right click, and select multi display control panel.

There's a button to disable as long as you have the newer driver from their website. The old drivers had a bug that caused this button to not work

Visualise Spots with dual monitors

I'm finding some eratic behaviour when using Visualise Spots with dual monitors.
I have Development open on one window and the Loupe view open on the other. When I click on the Visualise Spots both windows show the visualisation. When I click the button off - both windows switch to normal view - most of the time.
Occasionally it will switch off in the Development view but stay on the Loupe view on the second monitor. It only goes away when I switch to another image.
Is anyone else seeing this behaviour?
Roy

I have found that's it's linked to zoom level.
I can't quite make out what's going on but the behaviour is very strange.

Quick help with dual booting

I have hopped around on different distros and I found that Archlinux would be the best solution for me. However, I need help with dual booting Archlinux and Vista as I will need Vista around for one program and a game that do not work with any Linux distro that I have tried. I have not done a text based install before, I have only used newbie distros but I want to move on to Archlinux.
I will only need one partition for Vista and one for Arch. I believe I can achieve the goal of dual booting them by shrinking the vista partition, and then installing Arch in the remaining space and use GRUB to boot the necessary partitions when my laptop is powered on. This works with Ubuntu, so I assume it shall be the same basic concept with Arch. I can follow the instructions on installing, and the installation is easier than I had expected it to be. I have one question, how would I go about using the above technique that I mentioned during the install? I would like to know how to do it correctly, I cannot risk messing up Vista. I'm fifteen and my dad would be very frustrated if I did mess up Vista. I would appreciate some specific instructions, because I really like Arch from what I have read. I also look forward to being an active member in the community as well if all goes well.

Welcome!
Another young one I see! I'm currently 17, however I started using linux when I was 13 (8th grade year).
You can resize the vista partition by using gparted. You can download the gparted livecd from there website (http://gparted.sourceforge.net/download.php). I do not know specific directions, but it is pretty obvious how to resize, and if you need help you can probably google something like "resize partition gparted". I WARN YOU that you do risk data loss resizing the partition. I don't believe the risk is high, but it still there, so backup any important data that you may have in case something goes wrong!!
Do you have your own computer that you can experiment on? That might be a safe option than using your dads. I am been fortunate to have hand-me-down systems, but when I was young I made my dad angry quite a few times "experimenting!"
If your dad's system has enough juice, you may want to consider install arch in a virtual machine to get idea of however thing works. Following the Beginners Guide on the wiki will be you best bet for a successful and well configured machine (http://wiki.archlinux.org/index.php/Beginners_Guide). If you really want to play it safe you can even go as far as install windows in a virtual machine, resizing the partition, and installing arch in the same virtual machine.
I hate to say this, but if you absolutely can not mess up vista, I would advice against installing any other OS and messing with the partition scheme. As whenever you mess with the partitions you run a risk of messing up Vista (or any other os for that matter). If you don't already have your own computer which you can tinker with, it might not be a bad idea to look at getting one. They are becoming cheap, you can build one for about $300-$400USD, or buy one for probably around $400.
Hope this helps a bit...

Please help with strange monitor/Lightroom 4 interaction problem

I bought a Dell Ultrasharp U3011 yesterday, and I'm now facing a very strange problem. It's sort of related to the common discussed issue of Lightroom's color management, but there is a twist here. I'll explain.
The monitor I had been using (and still have) was a Samsung SyncMaster 244T. I had no problems at all with it.
With the U3011, I've run into this problem:
-When I view files in Lightroom 4, the colors are muted and contrast low. The same files seen in Xnview, ACDSee Pro (with the color management turned off), Digital Photo Professional (colorspace set to sRGB), are much more vivid. In Photoshop, if I use the default color setting, it looks muted like Lightroom (I'm guessing because Adobe products have default color profile set to ProPhoto RGB), but if I set the color profile to the monitor's profile, it becomes vivid and matches the other software I mentioned. If I use any other profile such as sRGB IEC81966-2.1, ProPhoto RGB, Adobe RGB, etc, it doesn't match the other software I mentioned. This is strange because the other ones match each other because they are set to sRGB, but in Photoshop, even if I set the color profile to sRGB, it still doesn't match.
-In Lightroom 4, even if I use Soft Proofing, nothing changes. It's as if Soft Proofing is broken--it doesn't do anything, no matter what color profile I choose.
-Now, here's the twist. I didn't have any of these problems when I use the 244T. This leads me to assume that the problem is how the U3011 is interacting with Lightroom. I did a quick comparison of opening up the same image on both monitors in ACDSee Pro, and they looked identical. (At this point, I had the U3011's preset set to sRGB. This is the only preset that makes the U3011 look identical to the 244T).
Next, I did an experiment, and I was very surprised by what happened. This is what I did:
With both monitors as a dual display setup, I turned on Before/After comparison in Lightroom (made sure both version had the same setting and look identical by copying the After's setting to Before). I then moved Lightroom's window so that one photo is seen on the U3011, and the other shows up on the 244T. And OMIGOD, they looked different! Why is this happening? I've already established that the same image looks identical on both monitors when viewed with ACDSee Pro, but in Lightroom, they looked different on each monitor.
And then things got even more weird. When I dragged the Lightroom window fully to one monitor or the other, Lightroom actually started changing the colors right before my eyes as it responded to which monitor was displaying which photo! Lightroom was somehow interacting with the monitor in real-time. So if the Before looked muted on U3011 and the After looked vivid on the 244T, when I drag the whole window into 244T, the muted Before will stay muted for about a second or so, and then it'll suddenly change and become identical to After. And when I did the reverse (drag the window into U3011), the reverse also happened--the vivid After will stay vivid on U3011 for about a second or so, and then it would suddenly change and become muted. Lightroom was identifying each monitor's color profile setting and changing the images according to which monitor was doing the displaying, and when the images were split between the two monitors, Lightroom was slitting them into two different settings to match whichever monitor is displaying which side.
So what the hell does that all mean, and what can I do to get Lightroom to display the photos so that they look the same as on all the other software I mentioned (so I don't have to play the guessing game of editing the images, export them out to other software to check how they turned out). Also, remember that I didn't have this problem with the 244T--Lightroom displayed the photos the same way as the other software I mentioned. The problem right now is that the U3011 is somehow causing Lightroom to display the photos differently, and no color profile presets in the OSD control can make them match.
I need to solve this problem, or else my last resort would be to return the U3011 and try another brand/model and see if that helps.
Any ideas?

Yes, that's basically sensible advice you got there (but I was more succinct ).
An important point that was mentioned over there is that you must not confuse document/source profile with monitor profile. They are both links in the color management chain, but they serve different purposes. The document profile defines the colors in a standard color space. The monitor profile describes the monitor's own native color space - its response to the RGB numbers it's fed. So one is translated into the other, by the application on the fly, through a normal profile conversion, and that way the colors appear on-screen as intended.
If those two profiles/color spaces are roughly similar, as they would be in the case of an sRGB document displayed on a standard gamut display - then you can get by without color management. It won't look too far off. But a wide gamut monitor changes the rules, because its native color space is not similar to sRGB, it's much closer to Adobe RGB.
Anyway, this is what color management is about. Any profile can be translated into any other. So in this context it doesn't really matter what color space the document is in - as long as you have a good monitor profile it will display correctly (within practical limitations). Lightroom is a sort of special case because its internal working color space is not one of the standard ones, instead it's a modified ProPhoto space with linear gamma. But the basic principle is exactly the same: source profile > monitor profile.
Just to go a little more in-depth while I'm at it: When you calibrate a display you actually do two separate things. You first calibrate it to a more or less standardized response. But that's just a linear one-dimensional correction. It does nothing about how color is actually reproduced, how red is red for instance. The calibration is global and affects everything system-wide because it's read into the video card or monitor hardware.
Then, once calibrated, a monitor profile is made. This is a full, complete and accurate description of the monitor's behavior, in three-dimensional color space. The precision level is much higher. This profile is used, by color managed applications like Lightroom and Photoshop, to display the image.
Other applications that are not color managed will simply ignore this profile, and send the RGB numbers straight through to the display, unmodified. With a standard gamut monitor (and an sRGB document) the difference won't be too dramatic and you may not notice it unless you look closely. But a wide gamut monitor will make the difference jump out immediately.

Mac and Windows with dual monitors Question

I use a Intel MacPro running Tiger with latest updates in my church. We use the Mac and Keynote 2.0.2 to present PowerPoint slides on the big screen (dual outputs). Everything was going well until the pastors upgraded to new computers running Vista and Office 2007. Now neither pastor's files will load into Keynote. It comes up with an error. The pastors have saved their files from PP as 2003 PPT files, and they still will not open. Error - unable to open file type. The one pastor went back to XP (dumped Vista) but still used the Office 2007 program and saved as PP2003, but the error still appears.
FYI - I noticed that Office 2007 saves with a file with the extension of .pptx instead of the .ppt. Checking the file they gave me shows that it is indead a .ppt file and not .pptx file. It makes no difference.
I believe it is an Office 2007 problem I'm dealing with. I have taken the .ppt file and loaded it onto the PC running PP 2003 and it loads fine, except for some format problems. I then resave it with a different name and tried to load that file (hoping it was converted) , with the same error showing. The problem is transfered with the file. Other files created with the PP 2003 program load fine into Keynote, so it has to be the Office2007 doing something.
So the questions are, is there an easy fix and still use the Keynote program, OR does Keynote 3 take care of this problem in the upgrade, OR should I install Win XP home or Pro and use parallels (which I have)? Would WinXP Home be enough to support the dual outputs and be fast enough? I am familiar with XP Pro not Home.
Any information you may have, could be a help. I need this resolved soon. I hate having to bring in the old Windows PC, after enjoying the quality of the Mac.

I have no issues streaming video on demand from all of the media sources which you have listed. My Mac mini is the Early '09, so my hardware is not as powerful as the newest Mac mini.

Thanks David - glad to here the Mini supports dual monitors, and you're not having any streaming issues. Did you have any special settings, like "no hardware acceleration"? Are you streaming HD content?
If it supports dual monitors, then I would think the iPad could be used as a second display and input device - the demos I've seen with Air Display (from Avatron Software") would accomplish what I'm looking for. Here is a demo at http://www.vimeo.com/16950420 showing the iPad working with a Windows machine, but I've seen them working with Macs as well.
Thanks again

ARD and controlling box with dual monitors!

My workstation at home has dual monitors,
when I connect to it with ARD both monitors are displayed, which means the window looks very wide, small and funny.
You can hardly see anything either.
(they are both highres)
I only need to see one monitor when I connect with ARD. Is there anyway I can get that working?

You can set ARD to view all screens at once or at real screen resolution. Click the 'Fit Screen in Window' icon (looks like an X with arrow points and a diamond in the middle).
I have had some issues with my Multi-screen machines colors displaying oddly while in 'Fit Screen in Window' mode, but turning it off fixes the issue and lets you auto scroll around like virtual Desktop.
Hope that helps.

Difficulties with Dual Monitors

Hi everyone,
I've been trying to edit my xorg.conf to get dual monitors going, but I can't get it going *exactly* the way I want it.
I have two monitors, both set up horizontally, side by side. I want the primary to be on the right monitor, and it to extend onto the monitor on the left side ie;
Left Monitor - Right Monitor (primary)
What usually happens is that the monitors are set up incorrectly, so if i want to drag something onto the left monitor, I need to drag the cursor to the right side of the right monitor ie, the setup ends being configured as
Right Monitor (primary) - Left Monitor
I hope that makes some sort of sense. At any rate, it's around the wrong way. I've fiddled around with the config file to no end but I just can't get it working.
The following is my xorg.conf file
Section "Device"
Identifier "Card0"
Driver "radeon"
Option "monitor-DVI-0" "Monitor0"
Option "monitor-DVI-1" "Monitor1"
EndSection
Section "Monitor"
Identifier "Monitor1"
Option "Primary" "True"
EndSection
Section "Monitor"
Identifier "Monitor0"
Option "LeftOf" "Monitor1"
Option "Primary" "False"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor1"
DefaultDepth 24
Subsection "Display"
Modes "1920x1200"
Virtual 3840 1200
EndSubSection
EndSection
If anyone can help me with this it would be much appreciated.
Thanks.

I was using xfce4, which sets the top and bottom panels in a separate setting. What monitor it chooses to associate the panels with is set there. I had it set to 'auto' and it was simply guessing the most appropriate monitor to place the panels. Setting it to show on the correct monitor, and setting it as the primary with xrandr solved the issue.
