OpenGL freezes computer with dual monitors and fglrx

I am trying to use the fglrx driver, and with a single monitor I seem to have gotten everything working.
However I am running into issues with two monitors. Basically, when I have two monitors any opengl program doesn't run properly.
There are two cases. If I use the xorg.conf generated by "aticonfig --initial", it still seems to detect the other monitor (although there is a black region on my gnome desktop). If an opengl program is run, the screen goes crazy where random pixels are changing different colors. I can end the program, and everything goes back to normal.
Using the program "amdcccle" I generated xorg.conf for dual monitors (I pasted it below). When I use this configuration, any opengl program completely freezes the computer instantly.
I have been looking for a while, but have not found any information that might lead to a solution. Does anyone here have any advice?

Hello.
I put my second monitor of a dual monitor set-up to the left of the main monitor - the one with the FC application, keyboard and mouse, etc. Trouble is the mouse kept hitting the left hand wall of my main monitor when I tried to send it to the second monitor. After a while I realized the mouse/computer thinks the second monitor is to its right, so I have to exit the right hand side of the main monitor to get to the one on the left.
Is there any way to instruct FC and the mouse that the second monitor is on the left? Can the mouse be instructed to "pass" through the left hand wall of the main monitor rather than the right? Or must the second monitor always go the right of the main monitor?
Thanks.
John

T61 worked with Dual Monitors and now it does not

I'm having trouble getting two monitors to work. They used to work fine. There have been no changes to hardware. Now the DVI monitor is blank. The DVI monitor does work with other computers (I'm working through a KVM switch).
T61 running XP Pro
Docking station
Worked well in the past
Took laptop to a meeting and used VGA and Laptop displaying the same information (needed to fool around with a few things to get that to work (FN-F7, Presentation Director, not really sure what worked)
Came back to docking station and my second monitor does not work anymore.
Control Panel
Shows two monitors (1 Bright, 2 Grayed)
Can select and choose extend on the second monitor (1 Bright, 2 Bright)
Apply reverts to (1 Bright and 2 Grayed)
NVIDIA Control Panel\
Set up multiple displays show choice is Only use one display (Single)
Second monitor choice is grayed
Presentation Director
No option is shown for two monitors
Laptop and monitor choices exist
BIOS Display
Tried Internal and PCI options (no joy with either)
Display is set to VGA & DVI
Any suggestions??

The docking station is a type 2504. I have both the VGA and the DVI port hooked up to identical flat screen monitors. I have no intention of messing with that because the setup is working successfully via a KVM switch. Both ports and both monitors are working. However, there is a problem with swithching modes with the Lenovo laptop. The problem does not exist with any other computer working through the KVM switch.
Please note that:
this Laptop on this docking station, at my home, with all wiring and monitors unchanged, has worked for a long time.
I took the laptop off the docking station, went to a meeting, hooked up to a projector, and successfully configured the laptop such that the laptop screen and the projector were displaying the same screen at the meeting.
Then, I brought the laptop back to the same old docking station at my home and tried to regain use of my dual monitors unsuccessfully.
Using Control Panel display, and all sorts of combinations of NVIDIA Control Panel, the 2nd monitor would not be consistently detected by NVIDIA Control Panel. During these attempts, on a few occasions, I had an option to Set Up Multiple Displays in NVIDIA Control Panel; but there was no success in choosing this option. Returning to NVIDIA Control Panel / Displays would not present Set Up Multiple Displays as a valid option (not present or greyed - can't remember). I even went through permutations with the laptop screen open and closed, warm boots, cold boots, searchign for new hardware, etc. Nothing was successful.
Although changing the display within Windows Control Panel / Display was an option, any attempt to extend or replicate the dispay on the second monitor would fail and Windows Control Panel / Display would go back to the single monitor configuration was not successful and effectively ignored by both Windows Control Panel / Display and NVIDIA Control Panel.
You may note the use of past tense. I simply gave up and went to doing productive work on one monitor. After a few weeks, I went back to NVIDIA Control Panel and the second monitor was detected. I was able to Display / Set-up Multiple Displays via NVIDIA Control Panel. Subseaquently, I was able to use Windows Control Panel Display to enable and configure the second monitor and both monitors started working again (without having made any changes to wiring etc).
I don't believe there is any difference in how I used NVIDIA Control Panel on this successful attempt than in any of the earlier failed attempts. There seems to be some sort of a problem with getting the Lenovo to recognize that the second monitor is really there. Please addess this part of the problem as I expect to repeat the process in an upcoming meeting with this laptop.
Thank you for your attention.

If I use the xf86-video-intel driver from extra, the xrandr command to do dual-outputs fails and I get both monitors showing the same desktop (mirrored mode). I switched to use AUR's xf86-video-intel-git (reading the forums it said this would fix the dual-monitor issue until extra moves to 2.12.0-2) and I do get the dual monitors working propery with the xrandr command, but I'm experiencing wierd effects. For every unminimized window on the desktop, if I put another window in front, the shadow of the window below stays on top of the window containing the focus. Hard to explain, so I'll use a photo:
That's what it looks like with xf89-video-intel-git, libdrm-git, dri-git, and anything else git and intel graphics related I can find. Any ideas what's wrong, or what I would even call this problem so I can look around and see if anyone else is having the same issues?

Ok, I went into the XFCE4 setting manager and opened the "Window Manager Tweaks" module, Under "Compositor" if I disable display compositing the shadowing effect is gone, making the display much more usable (thanks!). But now compositing does not work. Guess I'll go report this to XFCE, or is the XFCE compositing manager handled by someone else?

Stray Blob with Dual Monitors and a Stand Alone exe

Hi,
When I run any stand alone exe that I make on a dual monitor system (XP Media Center) I get a blob (see attachment) that is stuck in the middle of the primary monitor. I tried a very simple app and a complicated one. Clicking on this blob will make my app run in the foreground and if my app is in the foreground then the blob will show up in front of everything else except for my app.
I'm using LabVIEW 8.01.
Thanks,
Albert

I have a problem with itune in full screen blacking out my second monitor. How do I fix this problem?

Put something, anything on the second screen.
Does this only happen when iTunes is maximized?

Thinkpad W520 with Minidock+ Series 3 - Dual monitors and USB fail sporadically

Hello there,
I wonder if anyone has experienced problems ThinkPad W520 and Mini Dock Plus Series 3 (Part number: 433830U)? I run into problems with dual monitor and USB devices.
For dual monitor setup, sometimes only a single monitor is detected, sometimes no monitors are available in the NVidia control panel. Rigorous display detection doesn't help. Disabling Optimus in BIOS doesn't seem to affect it. After I dock and undock couple of times, reboot, unplug the power cord, it seems to resolve and both monitors work fine.
Also, I run into troubles with USB devices (keyboard/mouse). Sometimes they are not detected at all, but if I plug them into different USB ports on the mini dock, they are detected and work fine.
For me this problem happens about 50% of the time when I dock... Any ideas, insights or suggestions are greatly appreciated. Could it be a faulty Thinkpad, docking station or may be both? I really to upgrade next time to W530, but I've been through so many problems with W520, so I don't know if it's a good idea...
Thanks so much.
Solved!
Go to Solution.

If system update isn't finding anything, and the system works just fine on its own, it could potentially be a faulty Dock.
It could be overloaded. Could you try testing the dock using just one monitor, and no keyboard or mouse, to see if you run into the same issue. It would still be a faulty dock, but it may be a potential workaround for the time being.

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

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

There really isn't any workaround to the cost. You can't get the parts needed to fix it yourself. Only Apple has those parts and they do not sell them to end users.
Sure you could take it apart and clean everything and the screen might start working again but then it might not. Depending on what cause it to stop working in the first place. Like something got shorted out.

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

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.

Dual Monitors and Lr4

I am looking at switching from using Aperture and Photoshop, to Lightroom and Photoshop for my photography workflow. However during my free Lightroom trial, I have ran into a deal breaker with dual monitor support.
I use a Macbook pro w/ an external monitor for editing. In Photoshop and A3, I keep all my pallets, sliders, and thumbnails on the laptop screen, and display the full size image on the external display. I would like to do the same in Lightroom 4, however, there is one small problem.
When trying to achieve the same set up in Lightroom, I can view the image nicely on the external monitor, but I can't actually work on the external monitor. Example: If I decide a blemish needs touched up I can't use the spot removal tool on the large external display, but instead have to use it on the small laptop screen image. The same is true of the crop overlay and adjustment brushes. Also the fantastic option commands for mask overlay and sharpening, are not visible on the external display.
Please tell me there is someway to change this?
I strongly prefer LR4's sharpening and noise reduction, and feel I could reduce my reliance on CS6 for many images.
Thanks in advance,
Troy

My first encounter with Lightroom was similar to yours: Why the heck can't I move the panels where I want them? This is ridiculous...but after a while it grew on me.
There's no reason you can't have the main action on the large external monitor (as ssprengel says). But you have to get used to the idea right away that Lightroom is a single-screen application, and the second screen is just an extension used for an alternative view (grid/loupe/1:1). Don't fight it, it's just how it is.

That's absolutely right, that's what happened to me.

Lync 2013, text does not display in chat box. Windows 7 pc with dual monitors.

Has anyone experienced an issue with Lync 2013 where when someone sends a chat the text doesn't display in the chat box. Or on occasion when initiating a chat, the text typed in doesn't display? The person experiencing this
behavior has dual monitors and often times when she is working on a document - then goes to Lync and initiates a chat and types, the words do not display in the chat box. Her graphics drivers are current, (8.15.10.2869). At one point she was able to drag the
chat box over to the monitor on the left and then the text displayed. Since then she has received a brand new laptop, windows 7 and the Lync behavior continues but now her dragging the chat box to other monitor no longer resolve text display issue. Ideas?

Hi,
Did the issue happen if only use single monitor?
Please update to the latest version for Lync client 2013 and then test again.
Best Regards,

Using the GT70 with external monitor and lid closed

I wasn't sure where to post this question.
I have several laptops and use external monitors. I close the lid on the laptops and the display continues to work.
On the GT70, the system shuts down. It won't allow me to use the external keyboard and mouse or display the session.
Any suggestions if there is a configuration option to allow the GT70 to continue to function with external monitor and lid closed.

Yup. This is a windows setting. You need to go into your control panel -> power options -> "Choose when the computer sleeps" and "Choose what closing the lid does"
That should solve the problem. I currently have my GT70 hooked up to a 42" TV and I can close the lid and it stays on and the TV continues displaying as well. No problems. =]

MacBook Pro with external monitor and keyboard.

Hello, everyone.
I've tried to find the answer for this question but haven't found a clear answer with my Google search.
My older Powerbook G4 will not allow me to work with an external monitor and keyboard with the screen in a closed position. I am about to purchase a new MacBook Pro and would like to be able to use it at home with a larger monitor and keyboard but with the lid closed and its built-in screen turned off. Can this be done ?
How can a MacBook Pro be used (turned-on) with external monitor and keyboard while the lid is closed and the its screen is off ?
Thank you in advance for your answers.
Joseph

Hi Niel,
I have the same problem with my MacBook and I followed the instructions you posted. My issue is that when the computer wakes up after clicking the buttons on the keyboard it then quickly goes back to sleep. I can't seem to keep it awake when the lid is closed. I've been searching for an answer without any luck. Any idea how to solve this problem?
Thanks!
P.S. After I finished posting this message I figured out my problem. While fiddling with my computer and monitor, I inadvertently disconnected the power. After reconnecting the power, I was able to wake my computer and keep it awake. A note to other people having this issue: the computer must be connected to a power outlet to run in closed mode.
