I've got a desktop machine and a laptop, both running Ubuntu 10.04.
I want to be able to use the laptop screen as a secondary monitor for the desktop, like MaxiVista allows you to do with Windows (their home page has a nice animation showing what I'd like to accomplish).
Searching the web turned up that this is possible on Linux using software called xdmx.
I installed the xdmx and xdmx-tools packages from the repositories, but have been unsuccessful in getting it to work.
I've read somewhere that I should have both X servers listening on TCP, but I don't know how I'd do that. I've looked through the man pages for xdmx but that didn't really get me very far.
Does anyone have experience with getting xdmx up and running?
