Re: [xmonad] Issue 363 in xmonad: non-positive argument error on NVidia Xinerama set

Comment #8 on issue 363 by dominique.devriese@gmail.com: non-positive argument error on NVidia Xinerama set http://code.google.com/p/xmonad/issues/detail?id=363 I want to add a comment that this error message can also be caused by a wrong xmonad config (I spent some time looking for this). Briefly, if you have strictly more xinerama screens than initial workspaces in your xmonad config (I use DynamicWorkspaces), then you will see this crash, and it will go away if you add more initial workspaces in your xmonad config or if you change the screens config using xrandr so that there appear to be fewer screens on startup.
