    DMX did something like that, too (unified several X screens on different machines to one big screen).

      I currently have dual-display configuration and I want to extended it by several more displays, however the nvidia crap in my T510 won't allow having more than two displays so I thought about having the other displays connected to other computer interconnected by Ethernet.

      I see how this idea is difficult to implement. Maybe the way could be sending window's data to both xservers having them both render the window (with 3D acceleration) (always, or just when the window is going through screen edge). Or maybe if there is a way to force graphic card to rendr image to created framebuffer that covers display area of both xservers, we can send just pixel data through network.. perhaps 10Gb/s ethernet or thunderbolt or just use 1Gb/s interface (which would cause slow refresh rate on one X).

        An old rule kicks in, hehe. Don't ask how to do something you believe is the solution. Present the problem instead!
        All I can do for you now is ask one more control question. Then I am out of my knowledge jurisdiction. Do you want to have the desktop plane extended on all displays? Good luck with that. I sign off.

          Oh yeah I want the desktop plane extended on all displays.

          I'll try to reformulate the problem. Is it possible to add virtual display to Xorg? From this http://www.thinkwiki.org/wiki/Xorg_RandR_1.2#Summing_up I understand that there is already a virtual screen. I just really need to add there a virtual display so I can sample it by xwd.

            I've just found xserver-xorg-video-dummy driver. I guess by description that it's what I've been looking for. I'll make a multimonitor network setup with x11vnc and I may post some results here.
