I've recently bought one large monitor to replace my two smaller ones. I use i3 and as it turns out I miss the screen switching mechanism in a big way.

Is it possible to configure X11 to split my one physical screen into two virtual ones?


02:00.0 VGA compatible controller: NVIDIA Corporation GM204 [GeForce GTX 970] (rev a1)

I'm using the latest proprietary Nvidia drivers. I don't mind losing the ability to play games at this point if need be.


You want to check fakexrandr. Also XNest may occur to be helpful.


You could try a tiling window manager such as Ratpoison. It's not exactly what you asked, but it achieves what you want.

  • Thanks, I already use i3 though. Would rather not swap WMs and get back to my old habits by splitting the physical screen. – Phil Jackson May 22 '15 at 11:16
