Multiple virtual displays like linux - possible?

Hi, I'm a Linux user and I use/rely on multiple virtual displays to do my work; can't imagine living without this capabiltiy. Just curious if OSX's window manager allows this or not? I've looked around on the imac my daughter uses and in the Mountain Lion manual but can't find any info on it.
Thanks!

Gottcha! I finally found it in the book. That's what I'm talkin' 'bout. Thanks a bunch...I figured since OSX is Unix it should have it somewheres...LOL.

PS: Just clicked up 3 or 4 in Mission Control. That should do it. (I can't get used to the Apple Lingo and frankly silly names. Just say virtual display (what "spaces" really is) and i'm good with that. Sigh...)
If anyone in development cares, frankly this is a bit clutsy. You have to go to "mission control" to get to your other displays?

Does MAC support Virtual Desktop like Linux?

I was a Windows user, it's very easy to address a Window in XP on the taslbar. With MAC, I have difficulty. F9 is cool, but still not as easy as hover mouse over taksbar.
I wonder if MAC will do Virtual Desktop thing like Linux, so at least I can send different windows to different desktop for easy use.

There are a number of apps available on http://www.versiontracker.com that allow you to create and manage virtual desktops. I haven't used any, but a quick search brought up about 4 or 5.

Additional "Virtual" display.

Since I do a good deal of my color correction within Lightroom, I would like to request an additional "virtual" display like the second monitor preview window, floating wherever I want it, sizeable and the ability to easily lock a refrence image to it. I work with a reference image for color correction and ideally for color accuracy sake it should be on the same display and close to the image being corrected. At the same time, I use my second display window on another monitor while I work so it is unavailable to double as my floating reference window. I think adding a pop-up virtual display would be an invaluable tool for people like me that like to make quick color comparisons while adjusting but don't want to spare any more image space than I have to on my main display.

The second display window can be dragged onto the main display. Since it's normally in Full Screen mode you will need to switch this off (i.e. Cmd/Ctrl+Shift+F11)

I have 2 displays 1920 and 3840, use 1920 for every day work, some pages I would like to open in 3840 display, is this possible?

I have 2 displays 1920x1080 and 3840x2160,
I use 1920x1080 for every day work, some pages I would like to open in or redirect to the 3840x2160 display, is this possible?

No, but there is a developer tool that you can add a custom size to. It is called Responsive Design View.

Oracle Portal Virtual Host Enhacement for Multiple Virtual Hosts

I open the TAR Number: 4326752.996
The TAR is related to " REQUEST ASSISTANCE FOR MULTIPLE VIRTUAL HOSTS AND MULTIPLE PAGE GROUPS CONFIG. "
This is the Scenario: We Have Oracle Portal installed in a single Box. yes I know I know... but Not everybody is Yahoo or Google for Clusters and all the good stuff, we just want our website managed by Oracle Portal since all our ERP is running Oracle Database. Anyway. 1 Box running Oracle Portal Infrastructure and MidTier.
It turns out that our previous configuration we have the LAMP Solution with PHP, Apache with Virtual Servers configuration very trivial for a regular web server however we have about 6 Virtual domains.
For example:
www.abc.com
www.def.com
www.ghi.com
www.jkl.com
www.mno.com
www.pqr.com
We also like to post all our Intranet Information in this great Portal:
http://intranet.com
Where intranet.com is the same server but setup in our Internal DNS without be a Real Internet Register Domain.
So bottom line we start doing great with Install our single box install, later [GRRRRRR does not come by default in port 80 GRRRRRR, ok need to move and setup the virtual host to resolve our main External website www.abc.com ]
For starters ok it worked we have our main website running Oracle Portal.
Now is time to go to the step number 2.
Setup another Page Group in Portal to be the Page_Group_INTERNAL.
I figure if Apache can setup Virtual Hosts pointing to Independent parts of the File System without be shared. I was expecting some kind of custom configuration where I can setup httpd.conf to point to some specific PageGroups to make sure
www.abc.com => Page_Group_External
never share information with:
intranet.com => Page_Gorup_Internal
My TAR was very quick closed with the Argument that is not what It supposed to do.
Since a virtual host is a common thing to do on Linux and Apache, I wonder if You guys could list this as one of the default features to have multiple virtual domains assosiated with Page Groups that they never talk or share Resources I think that would be really great.
In the mean time I guess we have no option but to put a password for every internal page or take the risk of share our Information to the Internet. Perhaps designate another box with Oracle Portal but In that case Is not really cost/bennefit to use a killer technology for our external site since we just have no more than 30 pages.
Anyway just figure drop you guys a note any advise will be really appreciated.
Best Regards Dino.

Hi Martin,
1. To change the target URL of KM resources you can to the following:
Access the URL Generation Service Configuration by navigating to:
System Administration -> System Configuration -> Knowledge Management -> Configuration
Content Management -> Global Services -> URL Generator Service
Change the Host property to "portal.company.com".
2. You change the Port by opening the Visual Administrator and going to : Dispatcher -> Services -> HTTP Provider
Change there the "Ports" entry from (Port:50000,Type:http)to (Port:80,Type:http). Then go on "Save".
3. To remove the "/irj" from the portal URL you can create a index.jsp with the following content, and save it in the J2EE Documentation folder:
<Drive>:\usr\sap\<SAPSID>\JC<J2EE_instance_number>\j2ee\cluster\server0\apps\sap.com\com.sap.engine.docs.examples\servlet_jsp\_default\root
<%
//Send the redirect using server redirection (not client script)
//This will also send the HTTP GET parameters
String queryString = request.getQueryString() ;
if (queryString==null ) {
response.sendRedirect
("irj/servlet/prt/portal/prtroot/com.sap.portal.navigation.portallauncher.default") ;
} else {//redirect with HTTP GET parameters
response.sendRedirect
("irj/servlet/prt/portal/prtroot/com.sap.portal.navigation.portallauncher.default?" + queryString) ;
%>
Hope this helps,
Robert

Virtual Display when nobody is logged in

I manage a lot of Lion computers, and was wondering if this is possible: Is there a way to initiate a virtual display session via VNC when nobody is logged into a Lion computer? I'd really prefer if I could do this rather than take over the computer. I'd like it to just sit at the login screen while I do everything in the background.

I just tried selecting "virtual display" but the machine still mirrors what I do in VNC despite it saying it's on the virtual display. Any ideas?

Xfce4 virtual desktop configuration and possible alternatives

I’ve been a satisfied xfce4 user for some time now, but my needs have recently changed. In the past, I have used just a single Workspace/Desktop to meet my needs. Now, however, I find myself needing several virtual Desktops to better organize my workflow. For instance, I would like to have separate Desktops for different functions, such as: personal apps, business apps, utilities, remote desktop sessions, various VM’s, etc.
I know xfce4 supports multiple “Workspaces”, but I am currently unable to get them setup the way that I would like. For example:
Xfce4 session manager only seems to offer to save the session information from the first “Workspace”, meaning that I’ll have to start several apps in all the additional Workspaces manually after every restart of X.
The xfce4 Panel doesn’t appear to be customizable for each individual Workspace. I would like to have a different set of Launchers, Tray, and/or panel Widgets for different Workspaces if possible.
It would be convenient to have some Workspaces default to “tiled” and others to “floating” window presentation if possible, although this is of a lower priority to me.
Is something like this possible with xfce4? Maybe I can replace some xfce4 components with something else to obtain more functionality? Maybe something else altogether? Or, is this all just wishful thinking?
I hate to abandon xfce4 (custom themes, configurations, comfort level, etc),. But, I will if I can find a sufficient reason. Any thoughts or recommendations appreciated!

Hi ,
Personally , there is no problem with your server , it is just a mechanism like Identity Columns of SQL .
"Reuse of values – For a given identity property with specific seed/increment, the identity values are not reused by the engine. If a particular insert statement fails or if the insert statement is rolled back then the consumed
identity values are lost and will not be generated again. This can result in gaps when the subsequent identity values are generated."

Connection from ONE VM to multiple X-displays?

Hallo,
is it possible to display AWT/Swing components on multiple X11 displays (not screens)
from ONE virtual machine? Each display has its own name/ip-address.
Thanx

From the command line you can only "export DISPLAY" to one machine.
But, have a look at java.awt.GraphicsDevice and java.awt.GraphicsEnvironment.
They look promising, returning an array of screens.

Virtual Display Manager?

everybody is wanting me to get a dual monitor setup. personally, they make me feel like a chameleon with eyes going 2 directions, and the scientific research I'v looked at doesn't show a great benefit for dual monitors as much for maximum screen real estate.
I'd like to instead get an apple LED 27" or 30", if i need multiple displays, i figure i can use some sort of Virtual Display Manager or multiple-monitor simulator program to simulate multiple monitors. I haven't been able to track down such a software besides windows: http://www.ishadow.com/?tabid=115
does there exist a way to emulate multiple monitors withen a single monitor for mac snow leopard?

Yes, all installed, the Virtual PC version is Microsoft Virtual PC 6.0.156.0
Update - Resolved
Corrupt user profile in Virtual PC configurarion.

How to handle Multiple Conditional Display

I have a page (call it page 2) that one can navigate to using a column link from another page, or using a link from a list. On page 2 I have a region that I would like to conditionally display; display the region if they navigate using the list link, do not display if they navigate using the column link or if the page is in printer friendly mode. I can probably handle a multiple conditional display for a region using something like a PL/SQL Function Body returning boolean, is it possible to know which link was clicked?
Other suggestions would be greatly appreciated.
Regards
Mark

Sudheshna-
In my List, I set REQUEST to P2_PARAM. On page 2, in the region where I want to control the display, for Conditional Type I chose PL/SQL Function Body returning boolean. In Expresion 1 I have this code;
BEGIN
IF V('REQUEST') = 'P2_PARAM' THEN
RETURN TRUE;
ELSE
RETURN FALSE;
END IF;
END;
The ELSE, handles the times I do not want to display the region, in my case if I linked to the page from a column on a page other than page 2, or if I want the page in printer friendly mode.
Regards
Mark

Can multiple Virtual Devices use the same IVI Driver Sessions?

I am using Switch Executive 2.0 and I'm having problems creating multiple Virtual Devices.
I have created a virtual device on a development computer that has no hardware connected to it. This virtual device uses specific drivers to simulate the devices. The problem I'm having is that when I create a second virtual device and try to add the same IVI Switches as the first Virtual device, I'm getting the following error:
An error has occurred while attempting to access the device deviceA_ivi.
Error -223116 occurred:
Internal Software error occurred in Switches software. Please contact National Instruments Support.
File name: .\source\mxsWrappers\tMXSObject.cpp
Line Number 192:
Status Code: -223116
Can someone please explain why?

Can you please elaborate on how did you create those simulated devices? Namely, what does your IVI configuration look like? What does the driver session for the logical name look like? What's the software module? What's the hardware module? What is the driver setup string, and what is the simulation mode for the device in question?

W540 - Sound and Display in Linux

Hey dear supporter/user/reader!
After calming down due to the vast loss in quality of the new Lenovo ThinkPads (2.2k€ for such a plastic toy - rly?) I started installing a Debian sid with XFCE d/e. There were a couple of problems to solve, especially this rattly one-click-fits-all clickpad needed a lot of caring and compiling. And not to forget the first two days of my odyssey trying to boot up the machine with my OCZ Vertex 2 SSD installed with any format, partition table protocol or whatever firmware loaded - which was a sobering and vain experience. I ended up taking another SSD from my studio desktop which isn't only half the size but slower, too. 2.2k€ for a machine unable to boot a regular SSD - rly? Whatever, posting my whole snaggling-list would go far beyond the scope of this thread and we all know how capitalism and "consulting" works - so let's look forward.
There are lots of problems left but some of the major ones are:
Bad sound in Linux
Bad color reproduction from the 3k display in Linux
Sound:
In Windows the sound is quite nice. I know that it's a problem of alsa/pulseaudio drivers and that the community has to create appropriate drivers first. But there's no information around by now about the capabilities of the installed sound chip to create some usable workarounds:
Is there a subwoofer built in?
Or other channels/speakers I can route some signals to?
How is this full, brilliant and wide sound achieved in Windows?
Because just using the stereo speakers at the front edge of the notebook sounds really crappy. Routing the signal through an equalizer gets back some of the highs and the "bass" and eliminates some of the bugging mids around 1.5k but it is still far from the sound experience in Windows. And it brings in some problems because I have to setup a dirty workaround via DBus to select different presets in the e/q depending on the selected output device (speakers or headphone jack) which introduces more and more problems with muted channels after plugging a headphone aso.
Display:
The colors look quite okay in Windows, in Linux it's a yellowish-green mess. Since I read about the pretty poor quality of the built-in colorimeter before I ordered this device I didn't buy it in anticipation of the tutorials about using the Windows color profiles in Linux. Unfortunatley copying the profiles from the Windows HDD (C:\WINDOWS\System32\spool\drivers\color) and loading any of them via xicc, xcalib or any other tool handling color profiles does nothing to the color reproduction of the display. I found a profile made by a helpful person somewhere on the internet (notebookcheck? Unfortunately I don't remember) which makes this display kind of usable but it's far from being correct since it introduces a greenish inking at the lower end and a rose red one in the middle of the spectrum. Additionally the overall gamma curve doesn't fit that well. But at least it draws white as white and eliminates the overall lime style of the device.
Résumé:
Maybe I'm just an idiot, too dumb to correctly copy and apply color profiles or to use alsa/pulseaudio the correct way. If so I would be very happy about anyone who would lead me in the right direction. Perhaps someone stumbled over the same problems and has some fixes or at least ideas where to look at. Perhaps someone calibrated his 3k display with a professional colorimeter and is willing to share the results.
If someone is interested in e.g. my Xorg config, the amd64 DEB package for getting a usable clickpad, the slightly working color profile or other informations I'm able to share, please let me know.
Disclaimer:
I can understand if anyone is deterred by this rant in a way that she or he avoids to talk to such a poor goof, but perhaps someone understands my vast disappointment after spending a huge amount of money and a lot of time for a brand which is (was?) well known under (Linux-) enthusiasts for the outstanding build quality, the overwhelming compatibility and the ubergood hardware which was built into ThinkPad machines in the past. I owned, sold, recommended and installed lots of these notebooks before, my own last two machines were two t61p which I would call the peak in quality of this brand. But those times definetly seem to be over.
Thankful for every hint to make this thing more usable, best, Markus.
Your ads here!

Here's another profile I stumbled upon. It was made for the T540p shipped with the same display. It is a little more even, so less different colours in the overall grayscale and it has a better gamma curve. But it has an overall greenish touch just like the display without any profile but considerably less.
http://mein-neues-blog.de/files/t540p.icm
And to prevent users from searching I upped the profile from my last post to my blog, too:
http://mein-neues-blog.de/files/LEN40B5.icm
BTW I'm actually hacking a GTK application for manipulating the ramps of a LUT profile in realtime since those profiles are not that bad but need a little tweaking to fit my own display.

T530i multiple external displays without dock

Hello all,
I'm having an issue trying to set up a T530i with Intel HD Graphics 400 with multiple external displays. I have searched the forum and not found anything similar, it looks like most people are using docking stations with their configurations which I don't have. Here is what I'm trying to set up.
External + External + Laptop
Currently, I am running a VGA splitter to the External displays. This works as expected, replicating the display on both externals, as Windows only sees the connection as one external display.
My goal and endstate is to have the system recognize and operate as 3 seperate displays (extended desktop).
In my attempt to achieve this, I obtained a Mini Display Port to VGA converter, plugging one external display into each port (VGA and Mini Display port converted to VGA) the system now recognizes the a 3rd monitor, but it will not allow me to extend (or even activate it). I am only able to run 2 screens simultaneously. Whenever I try to activate the 3rd display ("extend desktop to this display") when I hit apply, I get an error message stating "unable to save display settings".
Is there a solution to this where I will be able to run all 3 displays? The only thing I have not tried is using a splitter on the Mini Display port as I do not currently have access to one.

Hi Bret,
This is a user-to-user discussion forum so your frustration needs to be directed at Apple. Unfortunately, there's no word from Apple directly as to why they do not offer multiple monitor support (on their website that I could find).
Regrettably, the next best thing is to reach out via the appropriate feedback section:
http://www.apple.com/feedback
I'm with you, though, the option would be nice.

Driving multiple exterrnal displays??

What would apple need to add to the MBPs to drive multiple external displays, perhaps two 30" displays like the G5s????

I probably should of posted this under MBP Displays sorry, if moderator could move it over that would be great.
