HELP: Can't pickup dual displays!

[niic]

Hi all,

I know this has been a topic heavily covered in the past however I've not been able to work out why I'm not able to pickup both monitors from those thread conversations/documentation. When I try to vnc in I always only get the primary.

I was on 1.0.6.5_x64 but I had difficulty trying to get dual displays working on this. 1.0.8.2_x64 apparently had this natively working!

** v1.0.8.2 Release
server
*added multiple monitors for non driver mode

I simply installed the download as server only so not full app. Still not able to see both monitors spanning my window.

Any help would be greatly appreciated. I'm running Windows7 64bit

Thanks,
Nick.

What happens with you click the switch display button on the viewer toolbar?

as well you can delete ultravnc.ini before start winvnc
if not exist, winvnc auto make new one and set new password on winvnc admin properties.

Hi... I don't get a viewer toolbar?

The config setup is Xvnc Free Edition 4.1.2 on a linux workstation and UltraVNC 1.0.8 SERVER installed on Windows7.

I need to vnc from Linux to Windows only. I can connect no problem however I can only view the primary desktop not both. Is there something I need to enable on the Windows side to allow both desktops?

Any help would be really appreciated.

Thanks,
Nick.

I don't know that multiple monitors are supported across different VNCs. (They may be; I just don't know.)

Perhaps you could try running the UltraVNC viewer in a Windows VM inside Linux, or else just use the browser based Javaviewer to connect to the Windows/UltraVNC target.

Browser based javaviewer? How do I go about testing that

Thanks for the reply!

Cheers

On the target server PC, right-click the system tray icon for UltraVNC, select Admin Properties, and checkmark "Enable JavaViewer". The default port is 5800.

Then, from any machine that can reach that PC (including remotely via port forwarding at the router) just run any web browser and navigate to http://TargetComputerPublicIPAddressOrDNSName:5800

If you have Java available on the remote client, you'll be running a rather nifty web-based version of the VNC viewer application.

Personally I'd change the default port, though, to modestly mitigate script kiddie attacks. And be sure to have a decent password set in VNC.


WHOOPS. Sorry, I just tested this. I thought the Java viewer included multiple monitor support, but I guess I was wrong.

That would have been useful info in the first post.

The switch monitors button is only available on the UltraVNC Windows viewer AFAIK.

I've never done it but you should be able to run the UltraVNC viewer with WINE.

So it's WINE, or a VM.

Would this, from the x11vnc documentation, help at all?

Q-102: Can I use x11vnc on a multi-headed display that is not Xinerama (i.e. separate screens :0.0, :0.1, ... for each monitor)?

You can, but it is a little bit awkward: you must start separate x11vnc processes for each screen, and on the viewing end start up separate VNC viewer processes connecting to them. e.g. on the remote end:

x11vnc -display :0.0 -bg -q -rfbport 5900
x11vnc -display :0.1 -bg -q -rfbport 5901

(this could be automated in the display manager Xsetup for example) and then on the local machine where you are sitting:

vncviewer somehost:0 &
vncviewer somehost:1 &

Note: if you are running on Solaris 8 or earlier you can easily hit up against the maximum of 6 shm segments per process (for Xsun in this case) from running multiple x11vnc processes. You should modify /etc/system as mentioned in another FAQ to increase the limit. It is probably also a good idea to run with the -onetile option in this case (to limit each x11vnc to 3 shm segments), or even -noshm to use no shm segments.

I wonder if the 0.1, 0.2 display syntax works with UltraVNC.
