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.

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.

WIn 7 PRO to Win 7 PRO Remote Desktop with matching 1920x1080 Dual Monitors

I have done quite a bit of looking and still do not know if WIn 7 PRO can connect to a to Win 7 PRO with Remote Desktop with matching 1920x1080 Dual Monitors. It seems like it cannot use dual monitors by the HELP file. But
then why does it have "Use all of my monitors for the remote session" as a selection in the Connection settings ? Just what is the real answer ? Both systems are 64 bit. If the answer is YES. Please tell me how !

Hello i-wonder-why,
To use this Remote Desktop Multimon feature, you must:
1.Connect using the Remote Desktop Client 7.0 (mstsc.exe) available initially on Windows 7/Windows Server 2008 R2.
2.Enable Multimon using one of the three methods described below:
a. Click “Use all monitors for the remote session” in the client (mstsc.exe) window.
b. Use the “/multimon” switch on the mstsc.exe command line.
c. Add “Use Multimon:i:1” to the RDP file.

Dual monitor and hw accel mutually exclusive (using Awesome WM)

Hi I've been using Arch for some months now and I have laptop (Lenovo x220 with integrated intel graphics) with an occasional dual monitor setup. Things were smooth, but I was having issues with video tearing, so I went trough the intel graphics arch wiki page and I was able to turn on hw acceleration and get rid of the video tearing by putting this in my /etc/X11/xorg.conf.d
# /etc/X11/xorc.conf.d/20-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
EndSection
The problem is that I add that file I no longer have proper dual monitor with extended desktop, the second monitor kind of mirrors the main one.
kind of, because I can move the pointer between the two monitors and is not duplicated, but the desktop (widows and awesome menu) is duplicated on the second monitor, but I can only interact with the windows using the mouse from the main monitor.
I usually do `$ xrandr --mode 1920x1080 --output HDMI1 --right-of LVDS1` to output to the second monitor, and it was working allright.
I've been trough arch and gentoo wiki looking for dual monitor/xorg config stuff to no avail yet.

I found a fix in this thread: http://forums.gentoo.org/viewtopic-p-71 … c9ec76f8b8
Adding `i915.semaphores=1` to my boot params allows me to use the TearFree option in xorg config, without X crashing and with a dual monitor setup.

Need videocard that supports dual monitors and Rotation -for PowerMac G5

I'm looking for a videocard that supports dual monitors and Rotation for PowerMac G5. I've got two Dell 2407WFP monitors rotated to 90 -I've been running an ATI Radeon X1900 256 pcie16 but apparently it is over heating -not even exactly sure if that indeed is the case but all the symptoms I've looked up online point to this problem. Anyways -just looking for a card that will do the job -I don't run games -this is just for work machine doing photoshop and related programs. Thanks for any help anyone may have!

Hi-
A flashed card is a WinPC card that has been modified to accept a Mac ROM to provide for Mac compatibility.
Occasionally, soldering and other physical modifications are required.
Without this modification, a WinPC graphics card cannot be used in a MAc.
Without this modification, Mac users are limited to only a handful of used, OEM options.
The Geforce 7800 GS is the only 7800 card that may be used in a G5 (or G4).
The card must have been or be converted to Mac compatibility.
For dual monitors (DVI) the best performance choices are the Geforce 6800 Ultra (flashed or OEM), a rare, but occasionally available Geforce 6800 GT (flashed), an OEM Radeon X800XT (use ADC/DVI adapter on ADC port) a rare and expensive Radeon FireGL X800 (flashed).
These are the only performance oriented cards to offer dual digital display support.
For less demanding graphics work, an OEM Radeon 9650 offers dual digital output.
Other OEM graphics cards will have either DVI/DVI or ADC/DVI.
All OEM graphics cards are only available as used.
All cards are easiest to obtain on eBay.
Prices vary, but deals can be found.
Expect to pay $150-$325 for any of the cards listed.
Any card considered MUST be stated as Mac compatible, unless you are willing to research and learn how to perform the necessary modifications.

Thinkpad T420 with Dock 4338 Dual External Monitors won't work

Hey Everyone,
I recently purchased a T420 with Dock Model 4338 and am trying to connect two external monitors. I want to have my desktop visible on my primary monitor with laptop closed and that desktop extended onto my second external monitors. Both external monitors are Dell 19", one is being ran through the VGA port on the dock and the other is a VGA cord that I put a VGA to DVI-D adapter on to run off of one of the DVI Ports on the dock. I can get my desktop to display on the main external monitor, and everything detects the other monitor fine, but the extended monitor remains black. The screen is on, and recognized as the button light on the monitor is green not yellow and i can scroll my mouse over to that window and i lose the mouse so it's extending just not visible. I have made sure that both monitors work by checking each individually in the VGA port and they are operational, but the DVI-D port doesn't seem to work on my second monitor.
I have done some pretty extensive searching and can't seem to get this to work. At my job I have a T430 with the same dock and dual monitor setup that took no time and works great. Does the T420 just not support this?
All help is appreciated.
Thank you all,
NickG

DVI-D don't support passive dvi to VGA adapter. You are better off with a displayport to VGA adapter, as they are cheaper then a dvi-d to VGA converter.

Connecting MBP w/Retina and Work Laptop with Switch to dual monitors

I have the latest MBP w/retina display and NVidia GT750M video card. I also have my work laptop (Dell, Win 7, HDMI out). I want to connect these to a dual monitor setup with a switch. I currently only have one monitor that is 1920 x 1080 and supports hdmi and dvi. I would like to buy another cost effective monitor to take advantage of my MBP's higer resolution and have that as my main monitor.
Next I would like to connect the two laptops to the dual monitor setup via switch to go back and forth between systems.
What is the best switch to buy for my needs? Does OS matter when selecting switches? Monitor recommendations are appreciated also.

I am also seeing lots of posts about Mavericks not working well with switches. Has this issue been resolved?

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?

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?

+Sorry. I mean "right" in the last sentence.+
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.

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

Dual monitor, and other questions....

I'm sorry for these questions if they've already been discussed... with all the back lash, I'm having a hard time wading through all the comments.
I have a macbookpro.
I use an external 24" monitor along with my 15" laptop for editing. My 15" is used for my canvas.
1: Can I use this set up with the new FCP X?
I use PPro CS5 currently and I like the way it handles media and saving my projects.
2: How does FCP X handle media?
2.a: Does it handle media like iPhoto / Aperture?
2.b: Are projects saved like in iMovie?
I keep all my media on external hard drives.
3: Will this be a problem with FCP X?
Thank you in advance for your help.
Tony

On my dual monitor Mac pro, the main monitor has the timeline and canvas. The second monitor has the events I think, basically the bin. You'd probably want to make your 24 the main monitor
FCP X handles media and projects a lot like iMovie. iTunes and iPhoto are accessed just like iMovie. You can save media to whatever drive you want although you can't really drill down to a particular location
Hope this helps

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.

Not pleased with PreEl 11 dual monitor mode

finally got PreEl 11 working on my PC and do not like the dual monitor mode. in previous PreEl programs i could detact the monitor and out it in to another screen and still have all the tools on the other screen. now the monitor and most of the tools move with the monitor so i have a split work space. not very handy at all. i am HOPING that someone can figure out a way to move just the monitor and not everything else with it...

If you've got a feature request, you should contact Adobe on their web site. (They're likely developing the next version now, so it's a good time to do so!)
This is a user-to-user help forum. We can't do anything about the interface itself. (And, yes, breaking it into a timeline and everything else is really the only option for version 11.)

[SOLVED] Dual monitors and raid - linux newb

Hi
I'm raginaot and I'll probably be asking a lot of dumb questions here in the near future
I just decided to say goodbye to windows for a while. Been wasting too much time gaming and it was either - switch to linux or - sell my computer and move to the desert. I'm gonna try the former first and see how it goes.
I managed to install arch and get gnome up and running with the help of the most awesome linux install guide I have ever seen and I installed the xf86-video-ati driver package but I'm having trouble getting it to recognise my 2 monitors.
I'll list my hardware specs before I go any further:
CPU: i7 920
RAM: 12GB (3x4) Mushkin Silverline 1333MHz
Motherboard: Gigabyte EX58-UD3R (rev 1.6)
GPU: ATI HD5870 1GB
Souncard: Auzentech X-fi forte
Monitors: Samsung 2693HM and Samsung 226BW
now the monitors seem to be stuck in mirrored mode, both showing the same image at 1280*1024 resolution
when I try to set them both to on and their native resolutions (1920*1200 and 1680*1050) in the display settings I get a message that says:
"the selected configuration for displays could not be applied
required virtual size does not fit available size: requested=(3600, 1200), minimum=(320, 200), maximum=(1920, 1920"
But when I unplug the 22" display, I can set the 26" to native res just fine and vice versa.
Now to the second issue...
I have 2 1TB drives in raid0, but in fdisk -l they appear as 2 seperate 1TB drives instead of 1 big 2TB like they're supposed to (see output below).
I guess I have to mount them in some special way, but I have no idea how. The raid worked right away in linux mint.

Glad you were able to figure out the RAID part - I can't really help you with that. As far as the dual monitor setup, I would suspect that you will need to do some stuff with the xorg config to get it working. I would say that xorg.log would be the first thing to look at - to see what is limiting the modes available to X. Maybe post the xorg.log and your x configuration
My post in this thread might give a bit of background on how X comes up with what resolutions it lets you choose.
