Re: Is it possible to extended the display, not a mirror, from a single headed graphics card?

Hi,
Are you trying to display one large screen split over two
monitors each plugged into *different computers*? Theoretically
that should be OK, if the network is good enough, but I suggest
that you try the easier problem with two video cards plugged
into one computer first.


I have done with two video cards. It is working fine. Now i want to do
the same with single head , two display.

One display will be connected by VGA, another display will be
connected through network.

I would like to capture the extended display interms of memory, then i
will transfer it across network. So that we can see the extended
display in remote machine.

My problem is how can i fake the Xserver that i have two video
cards(Actually i have only one), then only it will span the display.

Any ideas......................?

Hi ,

I think this is what i want. still i am elborating the objective in
detail

In the past I have run two monitors with each plugged into a video
card, where each card had only one VGA port. Each monitor was
displaying part of the desktop.

u can see the spanned display by using xinerama in multi-headed
graphics card.

Primary display in one monitor and secondary display in second
monitor.

Part of display is showing in primary(First head) and anonther part is
in secondary(second head).

I have two pc's which is connected in network. Each is having single
head graphics card.

In my primary display, i want to appear like my graphics card is
having two head, like virtual head.

So that i can capture the secondary display and send it to another pc
over network like VNC.

Extending the primary display over the network as Xdmx does.

What I have done in the past is plug two video cards into one
computer and have one large screen split over two monitors
(with each monitor plugged into a separate video card).
