Hi, I was an enthusiastic user of xinerama mode, but for some time now kde crashes when xinerama is activated. That's why I'm looking for working alternatives.
Supposedly xrandr can take over this functionality, but I can't get it to work. I am attaching the output of xrandr so that you can see what my setup looks like. I found a setup in the Ubuntu wiki that seems reasonable, but when I use it, only the center monitor displays part of the desktop. Right and left remain black. What am I missing?
