Software :: Virtual Display Driver For Mac?
Dec 26, 2006
I want to develop a "Virtual Display Driver" on Mac OS X which will create a (virtual)mirror image of original desktop on the same local machine i.e. at a time we can see two desktop on a single machine. When we will open the an application in original desktop same application is also mirrored in virtual desktop vice a versa. We can see two desktop in single monitor on a local machine.
I also want to know that is it require driver implementation or we can implement it just like an application?

I'd like a Terminal or AppleScript command to determine if a logged in user is using a virtual display.Â
The scenario is: user1 is in front of the local computer using user1 account (owns /dev/console); user2 is using using a virtual display for the local computer via ScreenSharing on a remote computer.Â
I know `stat -f%Su /dev/console` will give me who is in front of the local computer, but I need another command to determine if user2 is using a virtual display on the same local computer.Â

Got myself a 27" iMac i7 which was delivered today.
Been playing with it all day in OSX and initially installed Win7 but I the display driver keep crashing and I was getting artifacts on screen then the message saying that it had recovered successfully.
Having read that Win7 was not fully supported I assumed that this was the problem so installed Vista, but got the same problem.
Screen stalled, then goes blank for a second and then the error message in the task bar.
I have just ran all the MS updates and also installed the latest GFX driver from ATI to see if that makes a difference.
I have also just ran 3dmark06 and that ran OK but I was expecting the fans to kick in at some point

I installed bootbcamp today and windows 7 and after a period of time the following message would pop up after the screen froze and various artifacts would appear or the screen would be divided in half horizontally with artifacts in the middle.
"Display driver stopped responding and has successfully recovered"
I don't think this is a bootcamp driver issue. This is an issue between ATI and Microsoft and has been going on at least since 2007. Not much to say about it at this point, but I was wondering if anyone else has experienced this issue with the new iMac's and windows?

I am on my new 27" iMac last night when all of a sudden the display froze and pix-elated for a second and then went black and a few seconds turned back on with an error message at the bottom right screen saying my display adapter had stopped . . . . .
I was in Windows 7 64bit Professional at the time. I also noticed that Apple is wanting download a newer version of Boot Camp which I will download tonight!
I went to the ATI website and found a new driver dated 4-2010 and downloaded it. All seems well but was wondering if anyone has had the same issue?

The setup: MacPro 2.8GHz (Early 2008 model with 8 cores, 10 GB RAM, nVidia GeForce 8800GT, four internal hard drives of a total of 5.25 TB).
The symptoms: On Friday night I was booted into Windows Vista (64-bit) via Bootcamp as I had to do a bit of gaming not possible under OS X. Specifically I played All Points Bulletin (brand new MMO only for Windows). I found it to be an interesting idea to open another game at the same time (Warhammer Online). So I had both games running at once. After a couple of hours I received an error message ("Display driver has stopped responding and successfully recovered"). I had seen this message on a few occasions under Windows some months ago too. This time however the error message went away only to give me a slightly garbled image on screen. Psychedelic colours, quite funny looking in fact. I restarted Windows, and all looked normal again.
Then I opened browsers, word documents and so on, all normal. But as soon as I opened a game, the display was full of distortion and funny looking colours, dots and stripes, patterns vertically and horizontally. I also received the dreaded blue screen (which I had never had in Windows on my Mac since I installed it two years ago). I booted into OS X. All looked normal. Then I opened a game. Same symptoms as in Windows. I restarted. Opened only a simple YouTube video. Even then the display was making everything on screen impossible to see (and read). I did all the normal procedures (resetting PRAM, checking on logs for hints at what could be wrong and so on). I also ran the Apple hardware test, the extended version, which lasted two hours. It found nothing wrong.
I checked all connections and cables, I double checked the interiors of the Mac, no dust, all looked normal. I restarted the Mac into OS X once again, and this time I could only see the Apple logo during booting. After that it was mostly a black screen with some strange colour patterns. I'm writing this from another computer away from home as the Mac is all I have there at the moment, and I do not have access to any of its contents from here now (no logs to show you, no photos or videos). To me this looks definitely like the 8800GT has died completely, and I will bring it into an Apple retailer tomorrow for some testing, but I thought I'd just mention this here in case you guys should have any ideas. I would like to point out that I run iStat on my Mac and that I regularly check on the components temperatures and fan speeds.
Everything always look normal there (low temps in general, and fan speeds are mostly at their idle default settings, spinning up a little bit when doing graphically intensive tasks for example when video editing or playing a game). I did notice on Friday night that the power supply fan under OS X remained at its low idle setting all the time even when I tried to speed it up by using SMC Fan Control. The program managed to speed up all the other fans, but not the PSU fan. I do not know if that is any indication of something else going on. Sadly SMC Fan Control cannot control the GPU card's fan under OS X, but under Windows I do regularly control the GPU fan and temperature, and the card there has always been running between 60 and 84 degrees C.

I'm trying to connect my Mac (OSX 5) to a flat screen TV. To do so I just bought a USB 2.0 to HDMI ® Display Adapter w/ Audio (1920 x 1080). The mini CD containing the DisplayLink software drivers that came with the unit won't fit in my Mac CD drive. I then tried to download the correct driver from the DisplayLink website, "DisplayLink USB Graphics Macintosh Driver" which appears to be appropriate for OSX 5 (at [URL]).
This proceeds through the installation steps, then bombs out with the error message that "The following install step failed: run preinstall script for DisplayLink software. Contact the software manufacturer for assistance." In the hopes of finding a compatible driver, I looked for an earlier version of the driver on the DisplayLink site, but couldn't find one.

Whenever I try to use Screen Sharing to control this one particular Mac Mini, and someone else is using the mini, and I pick "Connect to Virtual Display", I get dropped to a grey linen screen. Like the login screen, but without a list of usernames or anything. There it sits. Here is what I see in the console of the mac mini when I try and use a virtual display from the other machine:Â

I had a Dell 1100 laser printer working on my iMac (G4 ball type) using a GIMP printer. I had to reset the queue and lost the driver. I can't remember which GIMP driver I used. Also, although I have loaded the latest GIMP s/w, I can't seem to get to them in Tiger 10.4.6.

We are trying to install/update to the NVIDIA 270.00.00f06 driver for the PNY Quadro FX4800 for Mac on our MacPro 3,1 with OSX 10.7.4. The system tells us "No Driver Update Needed for this System", and will not allow driver to be installed. Can anyone advise if the current driver is automatically installed or provided by Apple Updates. If not can you provide proper instructions on how to properly update the driver. Also how can we confirm what driver version is currently installed.

I thought I read awhile back someone posted on how to move the virtual memory to another hard drive. Now, I could be wrong, so I did a search and couldn't find the thread. So my question is on my Mac Pro, I have three HDs. 350GB that has OS. 500GB that is free. 1TB that has data. Is there a way to move the paging file (VM) so that it is being used on the 500GB hd?

like a mounth ago I bought a new Nahelm Mac Pro, 2,26 GHz, i'm very happy with it, here is the configuration:
16 gb ram ( 8 x2 gb ram)
640 gb + 2 x 1 TB Harddisk
two GT120 video card
Two Samsung T240 HD screens
and the other stuff are standart
The other day I didnt have anything to do so i was just having fun a little with some drawings on painter and photoshop while doing my everyday stuff (watching some streaming videos, or listening to music..etc) since it is my only computer, i do it for my work but also for my fun when I have nothing to do. When I watch a streaming video, let's say from youtube, i have it in full screen in one screen and on the other screen, I do my other stuff, like msn and doodling on photoshop and painter with my tablet..etc and my computer starts to lag, starts to respond very slowly, in a way that i cant do anything at all, and the streaming starts to play slow as well, then i reduce the size of the video instead of full screen and it looks a lil better for some time but then again it slows down my computer. Then when I check Activity Monitor I notice that I still have 10-12 GB free ram since I have only my everyday stuff open. but it shows 54 GB virtual memory and I dont understand what uses this much memory? I mean ok I make multi tab browsing..Etc but not more than I used to do on my old pc laptop with 4 gb ram, why does it use virtual memory when I still have 10 GB free ram? what should i do to avoid such situation other than not opening those applications at the same time? I wish that I was clear enough to explain my problem, I'm attaching a screenshot of my Activity Monitor,

I have files to burn into a cd, but all of my cd ran out. I was thinking about using a virtual clonedrive. Is there any way to make from a .iso file to a real cd file? (Has the cd icon, and not the white dvd player icon) It has to fool the mac to think that I inserted the cd, when it's just a virtual cd. Please don't put useless comments, such as 'Why don't you buy a cd'. The reason I want to use a virtual clonedrive is that I just need one cd, but they all sell in bundles of 30,50,etc.

I have an 40 GB SSD installed on my 2010 iMac 27" with a 2TB HDD hosting the users folder. I was running Transmission and encoding a DVD when I was told that I am out of Virtual Memory and must restart.
My question is: will using the SSD for Virtual Memory affect its performance down the line (as they should not be written to too much.) If so, how can I change my virtual memory storage location? *Xupport didn't work.

I am interested to see if any MR users out there use their Mac Pro for running multiple virtual machines concurrently? Plenty of folks run one or two even on a MBP with little problems at all. I am considering running 4 at the same time. Is this going to work? I plan on running Vmware Fusion 3 with 4 virtual machines with Windows 2003 Server Enterprise. This will hopefully work as my all-in-one virtual lab for my security research and development.
I was thinking of an 8 core 2.66 (2009) MP with 24GB of RAM to start with.

I have a mac powerbook g3 laptop and have successfully installed Virtual PC on. My problem is that when I open Virtual PC it just comes up with a black Virtual PC programme window. Once its done that I am unable to do any thing with Virtual PC because its frozen and in order to get out of the programme I have to force quit it. What do I do to get it to run windows 98? (I have both the Virtual PC disk and the windows 98 disk).

I installed TuneCloner to import audio-cds as mp3 (before figuring out that also iTune can do that). TuneClone has installed a virtual cd burner on my system, this is what System Profiler reports:
Hardware->Disc Burning -> Burning Devices: CDWriter TuneClone
Firmware Revision: 1.0
Interconnect: Virtual Interface
Profile Path: None
How can I remove it?? It makes Disk Utility crash and makes a cd icon appear on my desktop. I've read some post on this site about something like this, but I still couldn't get rid of my virtual drive... On TuneClone web site I was told how to hide the icon, but I don't want to just hide it... I'd like to get entirely rid of it!

My router has a firewall on it.
I use gmail and follow the usual precautions against opening strange documents, etc. (I also have a supplemental fan sitting under it)
I have no virus or malware or spyware protection on either the mac or the PC, although I do run occasional checks for them and have never found anything suspicious.

Has any one experienced how the MBA Rev A (1.6, 80 GB HD model) handles virtual machines? I need Windows sometimes due to my work (damn you Windows networks) and would love to be able to use my MBA.
I was thinking of using VMWare or VirtualBox from Sun.

Camino is my favorite browser, but its one big problem is that is uses up way too much of my memory. Is there any way to make it use more virtual memory and less physical - i.e., a memory quota? What would be the repercussions of doing this be?

I would like some input on the current Rev. B/SSD owners.
How does virtual machines run, specifically Windows XP Professional SP3?
My cousin is thinking about purchasing the Rev B SSD model but he requires Windows XP for work purposes. He won't be running much, just some basic software. I run a Vista virtual machine on my current 17" and it tends to studder a little sometimes.
