I want to make use of an old laptop by extending my the desktop from my main PC onto the monitor of this other, old laptop over a LAN connection.

I've looked into Xdmx/dmx, but the project seems to have been dead for a while.

Are there any other alternatives or will I have to cobble my own script together?

  • Have you tried remote desktop viewer ? – Srinivas Gowda May 14 '12 at 19:06
  • That doesn't allow me to extend the desktop, It's only a remote viewer. – jackweirdy May 14 '12 at 19:50
  • Synergy is much easier if you don't need to drag windows eg if you just want to run a browser on the extra display. – Alistair Buxton May 23 '12 at 9:51

You can download the source files from

http://dmx.cvs.sourceforge.net/viewvc/dmx/dmx/xc/

And just to keep you posted that the DMX software has been integrated into the X.org server software.

    You can browse/download the source code from dmx.cvs.sourceforge.net/viewvc/dmx/dmx/xc – Rupali May 25 '12 at 13:54
  • Thank you, I've managed to install it on Ubuntu 12 but on Ubuntu 13, there are a few dependency conflicts: libaudit1 vs libaudit0. I don't know whether it's possible to keep two version of a shared lib at the same time. Probably it does't matter, you just need one machine with Xdmx running but I wanted to extend the desktop of my other newer machine – ZiglioUK Sep 17 '13 at 2:08

Synergy is a nice program designed for something similar to what you want, it has intuitive GUI.

You won't be able to drag windows between displays though, since it does not use slave OS as another display device, but just sends keyboard/mouse input there.

http://www.virtualgl.org even allows openGL!
