Single screen KVM with dual screen setup

So here's the deal. I have dual 20" cinema displays hooked up to my Quad. I took one of the displays and hooked it up to my IOGear DVI KVM (http://www.iogear.com/main.php?loc=product&Item=GCS1764) so that that display could be shared with my Powerbook G4 and my Core Duo MacMini. However, when I change ports on the KVM, the secondary display "disappears" from the PowerMac and it starts freaking out. Sometimes it will just try to detect the screen (constant signal flickering) for a minute and then give up and operate as a single screen system but most of the time it tries to detect the screen for 2+ minutes until it just crashes the whole computer and then I have to reboot the PowerMac.
Any ideas?

Removing pin 16 on the DVI cable to the PoweMac might help. See the last item in: <http://www.gefen.com/kvm/support/faq/>

Full screen mode with dual screen

I have a Macbook Pro and use a second screen. I do like the new full screen feature but the app (safari, chrome, opera, firefox etc...) will only full screen with the primary screen (macbook screen). Really defeats the point of having two screens and having the full screen feature combined.
Any resolutions or is there a new update coming?
In Summary:
Full screen mode will only work on your primary monitor and not a separate screen. Please help.

Known issue.
Hopefully, it'll be fixed in a future update.

Is it possible to connect my mid 2010 Macbook Pro with my 21.5" iMac 11,2 so that I can work with dual screens?

Xmonad with dual screen strange bug or feature !

Hi,
I am running xmonad with dual screen. The strange thing (bug or feature) I noticed that when I move a window to another screen and then try to change the workspace, the window moves along to the same workspace but lands on the other screen.
Is there any way to switch off this feature. I googled a bit and replaced the greedyView parameter with view but it didn't help.
regards,
Hardik

How do I play a video in full-screen mode on one screen of a dual-screen Windows 7 system without blanking out the other screen?

How do I play a video in full-screen mode on one screen of a dual-screen Windows 7 system without blanking out the other screen? Not losing the other screen would be useful as I would like to, for example, monitor my emails whilst watching a video or to work on a project whilst watching an instructional video.
Note : Resizing a window to fill the screen is not acceptable as it still leaves unsightly borders.

Problems with dual screens

I am running an iMac 3.06 GHz, 4 GB RAM, 512 VRAM. I also use an external monitor connected via HDMI. When I run Color using dual screens the picture shows almost only black, and what isn't black is so saturated I can barely discern what the picture is. Does anyone know why this is happening and/or how I can fix it?

I'm not sure Color works properly with monitors connected in that manner. Color isn't accurate without proper monitoring, and you can't get proper monitoring with an iMac. By proper monitoring I mean an HDTV or broadcast monitor being fed a VIDEO signal via a hardware capture card (AJA, Decklink, Matrox). You can't get capture cards to work on iMacs, therefore you cannot properly monitor a video signal.
The display in the Color interface is not accurate at all. It is just a reference to see what frame you are on. It isn't designed to be used to judge the quality of the image. It has a much higher gamma (midrange) than is seen on the external monitor.
I'm assuming the monitor you are using is being fed a converted HDMI signal...converted from the DVI or Mini Display port on the computer. Well, that is a computer signal...not a video one. There's a difference. So this setup will not work...not with Color.
Sorry,
Shane

Any one help me with dual screen?

I am trying to get my LCD monitor work, which is plugged in VGA.
However, when i using "xrandr --output VGA --auto" to set it up, i get this failure "xrandr: cannot find crtc for output VGA"
i am using intel graphic card, and the result of "xrandr -q --verbose" is as follows,

how many monitors do you want to plugin? three? like damjan said, not sure if that works at all.
or are the hdmi outputs idle and you're just trying to plug in a second screen?
whats the exact problem? no output on that screen at all? or mirroring the internal one? in that case, try
xrandr --output VGA --right-of LVDS
(or left-of...)
can you plug that monitor in with hdmi? (adapter/etc) you might try that as well, maybe just the vga fails.
wow.. thank you konni... and thank damjan
i turned off HDMI-1, then I could get VGA work!
now i have dual screens, pretty cool.

Problem with dual screen (24" imac 2006 ver)

hi
i've got a 24" intel imac (2006 ver) and i've connected it using apple's mini-dvi => vga adapter to my 2nd 22" lcd monitor, a samsung 2232GW, which is set to 1680 x 1050.
however, the samsung lcd displays (when i'm using as dual screen) is quite blur and double imaged. quality is readable but very irritating. i'm also using the same monitor for my ps3 (uses the DVI side) and have no problem with any visual aspect. I've tried playing around with the settings like resolution and calibration and tuning but didn't help at all.
anyone might have any ideas and enlighten me on this issue?
thanks

Did you get any resolution to your question? I have the Samsung monitor almost like yours, and I posted two seconds ago. I think I have a similar problem. I had been using my Samsung with my PC, and just switched to Mac. I loved my Samsung, but now ,for the first time using as a second. Hooked up to mini dvi to dvi, and reported a glow, or tinge coming around any window that I may place on the Samsung.Also, when Ilook at the background around the window I can see that the resolution is not perfect and is breaking up a little. Did you try VGA? and did it help? Curious to know

[AwesomeWM] Applications locked to one screen in a dual monitor setup

Perhaps the title should be "Multiple Screens with multiple video cards." I imagine my confusion here is the reason I am unable to move clients from one screen to the other in awesome. Though the cursor moves fluidly between Screen1 and 2, MOD4+drag traps the cursor and the client on the current screen. MOD4+o brings the cursor to the upper left corner of the current screen. Openbox and fluxbox are similarly limited.
With my Xorg.conf I have $DISPLAY as :0.0 or :0.1 depending on which screen the terminal is open.
The closest I've come to a solution is xpra from the parti-all aur package. But, I haven't found a way to make it useful. I'm hoping there is an alternative configuration. Maybe something like xinerama or Zaphod?
I'd like to use xrandr but it seems thats a no go for multiple boards as of the the previous version. I cannot find documentation for 1.3.
http://wiki.debian.org/XStrikeForce/HowToRandR12 wrote:VI.5. Multi-board support broken - RandR 1.2 does not support multiple boards yet (it's planned for RandR 1.3). It means that any RandR 1.2 aware driver will crash the server if you have 2 boards. Even one board with a RandR 1.2 driver and another board with a classic driver does not work. It just crashes the X server.
Any ideas?

Err. My confusion is indeed the culprit. For anyone who might find themselves in a similar situation the nomenclature is as follows.
"Zaphod mode" on wikipedia is listed as a multi-seat configuration, however, I think it more often describes the set up in my posted xorg.conf. That is, the server has two independent screens associated with their respective device. Titling window managers seem to present multiple screens a la Zaphod. At least in awesome, each screen has its own set of tags. Xinerama is a soon to be deprecated extension merging multiple physical displays into a singular virtual one. It will be replaced with RandR. But, as of the current version of RandR, multi-board setups are not supported.
ATI and nVidia have proprietary implementations for multi-head configurations (Big Desktop and Twinview respectively). I assumed both cards would have to be same brand and either ATI or nv. So, I didn't look into this.
By the nature of Zaphod mode, applications exist only on one screen. They cannot easily be moved. Because the Xinerama extension implements one large virtual display, X clients can be displayed anywhere. This is apparently at the cost of direct rendering on both screens. Xinerama is also limited in that all screens have to have the same depth.
Having the Zaphod mode xorg config, enabling Xinerama just requires one line in the ServerLayout section:
Section "ServerLayout"
Option "Xinerama" "on"
However, if the resolution differs on the screens, screens with lower resolutions will have "dead space" where the rectangle of the virtual resolution is not displayed by the physical resolution of a screen. Moving the cursor into this area will pan the screen to show the previously hidden area and hiding what was previously visible. This means an application fullscreened on the screen with the lower resolution will never be completely visible.
To enforce physical resolutions in the virtual screen also only requires one line. In the display subsection of the lower resolution screen section, setting the virtual display to the same as the mode will remove the dead area.
Section "Screen"
Identifier "Screen1"
SubSection "Display"
Modes "1280x1024"

Please reply if I've gotten anything wrong!

How to darken only one screen in a dual screen setup ??

Hi All,
I have a dual screen set-up probably like many of you and sometimes I prefer to use LR only on 1 screen. That allows me to work on Photoshop or read my emails or whatever else I'd prefer to do on the other screen. My dilemma is when in Lightroom & I press the letter L to darken the screen around my image, for better viewing, it also darkens the other screen that I'm working with. Is there a way to prevent both screens from darkening?? Thanks Ron
PS: Apologies if this has been addressed previously as I could not locate it

Thank you digitaldog, I didn't think so either

TooltipText used with dual screen problem

Hi,
In my application I use a dual screen, so JComponent may be either on one screen or the other.
My problem is when the mouse rolls over a JComponent on the right screen, the Tooltiptext associated is displayed onto the left screen.
Any idea if I could display it automatically on the good screen or if I have to implement myself the display ?
Thx for advance

Screen sharing with dual monitors

I have a user on the network with a 13" MBP w/ 10.6.8 with an external display (23" Dell LED) set up to its right. The user typically leaves Mail open on the 13" display and runs her other apps on the external display. I'm running a 17" MBP w/ 10.8.1 with a 27" LED Cinema Display set up to its right.
When I try to share her screen, things go strange. It used to show the two displays correctly in a large window on my LED, but at some point when I was running Lion, and for no apparent reason (I didn't notice it immediately after an update, for example), the whole thing seemed to shift to the right by one screen width. Honestly, I can't think of a way to describe it, but I can simultaneously give you a screen shot and show off my amazing 'Shop skrillz. Behold:
Please forgive the atrocity that is this pixel homocide. If you tell me what's wrong with the screen sharing and how to fix it, I promise never to destroy harmless pixels again. Anytime soon, anyway.

Hi,
They could of course set the screen/Monitor to Mirror for a while as well
Also in the arrangement part of the Displays they could set it to have on on top of the other which might display slightly better if your Screen is 4 X 4 ratio

How to keep slideshow on one screen in a dual monitor setup

The slideshow shows on my laptop screen which is fine, but iPhoto '09 commandeers my external monitor as well, making it black/blank and unusable during the slide show. How can I continue to work and use my external monitor while playing a slideshow on my laptop screen?

iPhoto doesn't support dual screens. Send a feature request to http://www.apple.com/feedback/iphoto.html.

IChat screen sharing with dual monitors on client

Hello,
I'm trying to help a buddy out via screen sharing. The problem is he has two monitors. When I connect, they both appear as one display on my monitor resulting in a very small & hard to view image.
Is there a way to only show one monitor at a time? I know this works with regular screen sharing when Macs are on the same LAN, but I can't figure out how to do it via iChat.
thanks,
Shaun

Frozen system when booting with dual-head setup (updates)

Hi guys,
I made a fresh install a couple of weeks ago and I configured my system for a dual-head setup following the wiki. I activated KMS and added radeon to the kernel parameters.
My xorg.conf looks like this:
Section "Monitor"
Identifier "DVI-0"
Option "PreferredMode" "1920x1080"
Option "Position" "0 0"
EndSection
Section "Monitor"
Identifier "HDMI-0"
Option "PreferredMode" "1920x1080"
Option "Position" "1920 0"
EndSection
I was having random freezes for a couple of days, but I didn't pay too much attention to it. I hard rebooted my computer when it froze and it could boot normally that second time.
But after yesterday, last update to the open source drivers xf86-video-ati (1:7.5.0-2) and lib32-mesa-libgl (10.5.2-1), my system doesn't boot unless I disconnect one of the screens. When only one screen it's connected everything is fine. If I plug the second screen, it pops up the KDE service to configurate the second screen but as soon I press 'apply the chages' my system freezes and I had to hard reboot.
I've tried all possible combinations usingt different outputs from the screens, getting the same results. Two of them connected --> freezes after grub loading. One connected --> boot Ok, but as soon as I plug the second one and I apply changes, freezes.
I found one configuration that doesn't freeze my system. When I plug the second screen, as I said, KDE service automatically pops up. Before I was changing the positions of the screen, one beside the other one, and my system freezes when I apply the changes. If I just left the default configuration (one screen in top of the other), it doesn't freeze my system. After that, I can rearrange the screens, as I need them, and it doesn't freeze.
