This tool enables controlling one X display with the mouse and keyboard of another X display.
One interesting thing to note about x2x is that it has a long history, dating back to a time when window managers were simpler, and displays were more basic in design. Despite its simplicity, however, x2x has gained a wealth of knowledge about X11 implementations over the years, and this knowledge is put to good use in the tool's current iteration.
But while x2x has served many users well over the years, there are a few assumptions that have persisted throughout its lifetime that now need to be reconsidered. To this end, the software's developers are looking for a talented and adventurous individual who can dive deep into x2x's inner workings and write a new version that's better adapted to the demands of modern life.
Among the specific challenges that such a developer would need to take on are allowing for dynamically attached and detached displays, as well as supporting more complex data transfers through the X selections and Xinerama. If you're up to the task, though, then x2x could be a great opportunity to make a mark on the world of software development.
