Virtual Display Driver for Mac

skumar2011 · #1 December 26th, 2006, 05:17 AM

Hi Guys,

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?

Please give me any idea how to proceed.
Any helpful link is very much helpful for me.

Thankx.

Sunil

I don't exactly understand. You want _one_ display split in half and both the left and right (or top and bottom) half show exactly the same thing?

Hi fryke,
First of all thanks to showing your interest in solving my problems.

I don't want to split one display in half.

I want to create a virtual image of the whole desktop on the same local machine. Where we can see two same desktop at a time in single monitor one will be the original desktop and second will be the virtually created. It is something like mirroring the monitor of a local machine. An action on any desktop will also be reflected on other desktop.

waiting for reply.

So you have _two_ displays connected, then. This already exists. Just select "video mirroring" in the Displays preference pane.

OR, you could use something that already exists - VirtueDesktops

Thanks for reply.

The link which u have mentioned there is one application named "VirtueDesktops". This application maintain the different desktop session.
As I have mentioned in my post I want to develop a driver or an application which will create the Virtual Desktop on the same monitor. Its functionality like VNC which works on network or internet where VNCViewer can see the VNCServer Desktop. I don't want to create two application like VNCServer and VNCViewer ,I want to create single driver or application which will show my own desktop in the same monitor where my original desktop is i.e. we can see two desktop at a time on a single monitor,one will be the original and second will be the virtually created. If we pass any event like launching the an application or opening a folder etc. in either of the desktop same thing mirrored in the second desktop on the same monitor.

Call me stupid, but what you're saying doesn't make any sense to me.

You want to have a duplicate desktop on top of the original?

Or are you doing this for network use?

Please explain in more detail

As for a VNC Viewer, it doesn't see another desktop, it sees the original/normal desktop when you connect.

yes I want to have a duplicate desktop on top or beside of the original desktop.
I want to create a duplicate copy of whole desktop on the local machine not on the network and we can see both the desktop (original and duplicate) in a single monitor.
