T420 Linux Multiple Monitors

Running RHEL6.4 T420 4180-F66 I have the Dock series 3.
I'm looking to have 2 23" LCD monitors with the laptop screen working at the same time. I can't get it to work i've tried 100 different ways and can't seem to find anything online except for third party software that is no longer supported for RHEL 6.4 I'm currently running Nvidia driver 319.17 please help.
Thanks

Quick note - you may want to look up the specific dock you have. As I reviewed them, at least one specified that two external displays can be used but that the Thinkpad display would be disabled. The specific one I saw was this : http://support.lenovo.com/en_US/product-and-parts/detail.page?&LegacyDocID=MIGR-72873.

T420 with Multiple Monitors

I have a T420, with a Dock series 3 (model 4338). I would like to set it up to have 2 external monitors and to also use the laptops display. The KB references the Optimus drivers, which I do not have. My display adapter is recognized as an Intel (R) HD Graphics Family. Is there a way to also use the laptop display or do I have to have the Optimus to enable it?
Thanks in advance

Solved!
Go to Solution.

with your laptop this method is not possible, you would need the Nvidia equipped GPU to do this.
However, you can run the laptop with an additional external screen by getting a usb2dvi converter or an eGPU solution.

How to use different wallpapers on multiple monitors with Linux

Umm...ok. I use XFCE4 as my DM. It allows me to have a different wallpaper on each desktop.
Though I'm not interested in other DMs, what DMs would require that I use this third party tool?

If you have multiple monitors and run Linux, you may want to display different images as your wallpaper on each monitor. There's a utility for that – Nitrogen. The blackMORE Ops blog has a nice how-to on getting Nitrogen and configuring it, with step-by-step instructions and plenty of screenshots.

VMware Fusion on multiple monitors with Linux Guest

I am running VMware Fusion 7.1.1 on a MBP with a retina display and two external monitors. The guest OS is Ubuntu 14.04 with the i3 window manager. When switching to "Use all Displays in Full Screen" the view is mirrored on all three screens but xrandr is only reporting one display attached.

Can you have multiple users working off the same Mac pro at the same time with multiple monitors but doing different things?

I'm buying desktops for a start up company and was wondering if I could purchase a single Mac Pro and run multiple monitors to allow multiple users to work on the computer at the same time. These users would be doing different tasks but I would hope to accomplish that on a single desktop. I know that screen sharing is possible but with only one user controlling both of the screens. Thanks in advance, sorry for my apple ignorance!

A lot of companies are buying or leasing laptops to be used at the office by day, and carried home at night.
Some companies are doing "Bring your own device". Bring a device to receive email -- computer/smartphone/tablet you already have, or have an allowance to buy one for your use.
If Capital is short (and when is it not) leasing computers, to be turned in a few years, can be a huge savings because the cost is expensed as incurred. The alternative is laying out cash today, but not being able to expense the cost this year. Instead, the computer expense must be recovered over their useful life (often five years) through depreciation.

You cannot shadow a session with multiple monitors enabled in Windows Server 2008 R2

Searching through the forums (and according to KB2484290) it appears that there is no solution to this problem. We are rolling out thin clients that are using dual monitors exclusively and we were very surprised to find out that we couldn't shadow
sessions with dual monitors (which to us means that we can't shadow ANY sessions). This now completely changes our approach to managing these devices.
We are running Windows Server 2008 R2 SP1 with Remote Desktop Services installed. The thin clients are running Windows Embedded Standard 7 with the latest updates / RDP client. All steps have been followed to ensure that the apropriate settings and
permissions have been set up to allow access into the session.
We tested by unchecking the RDP setting “use all my monitors for the remote session”, with that setting disabled shadowing worked
Questions:
1. KB2484290 is from Dec 2010 - It's now April 2012, is there a workaround / hotfix for this issue that will allow us to shadow sessions using the native Microsoft tools?
2. Are there any recommended alternatives (software)? Free/Paid - doesn't matter we just need something that will work. I'm sure there are a few options out there but I am looking for suggestions for what people have used in the past that worked
best for them to help us narrow down the choices.

Hi,
In my experience, so far, the workaround is Remote Assistance, Remote Assistance supports multiple monitors, and is the presently recommended solution if you need this functionality. Remote Assistance is a Windows Server Feature that must be explicitly installed
on Windows Server 2008 R2; it is already installed with the client versions of the operating system.

http://technet.microsoft.com/en-us/library/cc770456(v=ws.10).aspx
As far as I know, there are some third-party tools can be used as the solution, such as Teamviewer, ISL Online, etc.

How to set up multiple monitors

I got a 27" 3.1 gz Imac for Christmas. I need to run multiple monitors on it.
#1 How many monitors will it support?
#2 How do I hook them up to the Imac?
#3 What hardware do I need in order to do this?
Phillip

This link is talking about using the Imac as a display for another computer. So basically, this article is telling me how I can use my Imac as a display monitor. That is not what I am trying to do.
I want to use multiple monitors on this Imac.

Wanting to use multiple monitors on HP hpe210Y w-DVI-I and HDMI. Audio: 5.1 Surround

I have a HP Elite hpe210y with only two outputs of which are: 1) DVI-I and 2) HDMI. My situation is that I have 2 new HP Monitors with VGA Cables. I have an adapter for DVI-I to VGA and also VGA to Dual VGA. I do NOT want the monitors to work as Duplicates however. I want the second monitor to be an extension. I am also interested in getting even 2 more monitors in teh near future for a total of 4.
Is there some way I can get two monitors to work off one DVI-I ?
Will I be able to upgrade to up to 4 monitors?
Is there a part I need?
Wanted to mention that my OS is Win7 Home Premium 64 bit. I use IE9, Chrome and Firefox
I would of never bought this from Best Buy if I had known in advance that there was just the one regular output. I see they have one called a Phoenix which I may look into.
Thank you in advance for your time and consideration.

>Is there some way I can get two monitors to work off one DVI-I ?
I've not yet seen a solution for that.
You can use a hdmi2vga adapter for the second port.
>Will I be able to upgrade to up to 4 monitors?
>Is there a part I need?
you can try one of these:
http://www.evga.com/products/pdf/100-U2-UV19-TR.pdf
http://www.amazon.com/Kensington-Universal-Multi-Display-Adapter-Black/dp/B002F9NSMQ/ref=pd_cp_e_1
http://aluratek.com/usb-2-0-high-resolution-vga-adapter
They will use your current graphics device.
If you are looking for a new solution - I've read about DisplayPort version 1.2 that can do 'daisy-chain connection' with multiple monitors. But this you have to 'google' yourself.

Can i have multiple monitor with my mac mini ?

Can i have multiple monitor with my mac mini like i do with my PC ? 2 differents screens.. not mirror.

There's lots of Mac Mini models since 2006 or so. What do you have?
Most support two monitors but how you do it is different depending on model.
Put this phrase into Google
dual monitors, mac mini
and you'll come up with the solution needed based on which MM you have.

VMware Fusion question - Multiple Monitors

I apologize if this is in the wrong area, but I am desperate for some help. I have also posted this same question in the VMware communities but I have not had any luck with anyone responding yet.
It seems that I am having an issue with my virtual machine (windows XP) viewing in full screen or unity across my multiple monitor setup on my Mac Pro. Every time I go to view in full screen or unity I get a VMware popup warning/error that reads:
The virtual machine "Windows XP Professional" is configured for a smaller display size than the one your Mac is currently using. VMware Fusion needs to shut down your virtual machine to enable support for your Mac's display size in Full Screen. Do you want to shut down this virtual machine now?
I have two options, one to shut down, or one to go into full screen. If I go into full screen, full screen works with the correct resolution and everything looks great except its only in the one monitor (not the multiple monitor). If I shut down and restart the virtual machine and try to go to full screen I get the same error.
The VMware tools have been installed and I did go to the view, use all displays in full screen opiton.
My current setup is a mac pro with 3 monitors using 2 NVIDIA GeForce 8800 GT Video Cards.
Any help would be greatly appreciated!
Thanks

I found a link to a VMWare Knowledge Base entry about specifying video ram in Fusion 1. Maybe it is still true.

How do I operate multiple monitors on my HP Pavilion Slimline Pavilion s3600t?

Hello HP Forum,
I am looking to operate 2 monitors on my HP Pavilion Slimline Pavilion s3600t that currently has GeForce 7100/NVIDIA nForce 630i. I am not a computer technician and only semi-tech saavy (less than more). I was told I needed a video card; however, I don't know what I need nor how to install it. Can anyone tell me what I type of video card I need to purchase (and why) and then point me to a video or instructions on install?
Further, what would it take for a computer to operate 3 monitors? Would this computer capable of operating 3 monitors? And what would that entail/how does it compare to installing options for 2 monitors?
Thanks for your help guys!
Cheers

Multiple monitors on laptop: iTunes crashes upon display lock

I have a laptop running XP Pro with an external monitor attached as an extended desktop. When I use iTunes (6.0.5.20) and lock my screen for any reason (close lid, screen saver activates, etc.), iTunes freezes and throws up an "Unsupported Display" window - or at least tries to: it appears in the taskbar but can't be viewed, opened, or closed. Only upon killing it (along with iTunes) can I continue to use my computer.
Anyone have a fix? I'm not the first to run into this; see for example:
http://forums.ilounge.com/showthread.php?postid=743115
Thanks.

I have a desktop with multiple monitors, and I have had the same sorts of problems. For me, iTunes 6 would display a dialog box that says "Unsupported Display" when I unlock the screens, though I was able to see it and dismiss it and life was good. Now, with iTunes 7, I can see that it tried to display an "Unsupported Display" dialog, but it crashed as well...
Here is the stack trace of the crash, in case an Apple Engineer sees this post: (QuickTime.qts 7.1.3.100 and iTunes.exe 7.0.0.70)

Imac multiple monitors

Hi
I have a weird startup problem on my iMac 27". It boots past the apple logo and blue screen but then I getaway white screen with random grey checkers all over the place!
I had issues with my snow leopard install which we're fixed after a fcsk command.
For some annoying reason I can't boot to a different USB or flash drive as I don't get past the mac logo!
Any help would be appreciated

Sorry nothing to do with multiple monitors!! My 1st post, don't know where that came from!

Feature Request - Better Multiple Monitor Support

Lightroom's support for a second display has definitely helped my workflow. I hope the team will consider adding more flexible multiple monitor support in version 4. Here's why.
I've recently experimented with running one of my three screens in portrait mode. When this screen hosts Lightroom's secondary display window in Loupe view, my verticals finally get equal real estate for editing. While I've not done hard statistics on my library, I know more than 50% of my imagery is in portrait orientation.
I'd like to see LR V4 support three or more screens so I could set up as follow:
Screen 1 - main lightroom interface, would not need to be calibrated, for controls and navigation
Screen 2 - Portrait orientation, loupe view - this would be a calibrated display, all develop changes to verticals would be judged on this screen
Screen 3 - Landscape orientation, loupe view - another calibrated display, all develop changes to horizontals would be judged on this screen
If Adobe could make the app intelligent enough to route the image to the correct screen based on orientation (recognizing and respecting cropping that could change orientation) my edit sessions would certainly speed up and I could maximize the productivity of multiple screens.
I'd be happy with this, but I'm also stymied by the need to switch back to Library mode to tag images when my primary workflow has me in develop. Ultimately everything depends on the quality of the image. Before I invest in image-specific meta data, I have to process or at least "test-process" an image. IMO the Quick Develop panel is useless, once you become accustomed to the granular control of the develop sliders, it just doesn't cut it.
In the three monitor setup I described above I'd love to be able to configure screen 1, with a combination of panels from Library and Develop, so I could stay "develop centric" with immediate access to keywording and meta. The two additional screens would intelligently handle image display.
I think this might speed my workflow by 33% and having just returned from a Tour de France project that generated 23,000 images I need all the productivity help I can get.

VeloDramatic wrote:
Thanks for all those votes Rob. Now we just need to get the other 999,999 on board.
Actually, this topic has come up a lot on this forum. At this point, I think we just need to get Adobe on board.
VeloDramatic wrote:
There may be another thread for this one additional thought. If Adobe does improve multiple monitor support, we should be able to optimize our previews for those screens. Even after prerendering 1:1 previews there are issues with DEVELOP doing its own thing (I believe) each time a new image is loaded. I make extensive use of the PREVIOUS button moving through my shoots and there's always a lag of one or two seconds while the develop preview loads before the button is active. In a desktop environment where multiple screens allow landscape and portrait images to be displayed full screen I'd argue that 100% of the host screen resolution would be the ideal preview. Hope that made sense.
Yes, faster switching would be nice. I'm not sure what that would take. As it stands, there's like "9" previews generated when you do 1:1s - 100% down to tiny thumbnails. Still, one at exact monitor size that does not need to be resized at all does seem like it would be the fastest - I'm a bit on a limb though at this point.
