Nah. In the beginning, there was X11. X11 defined what I will call "protocol screens". In this mode, only the mouse could move between screens. You can even run different window managers on the different screens. But people wanted to move windows between screens, so Xinerama is created. To 'old' clients, Xinerama looks like a single, big protocol screen. However, only parts of it are visible. You can ask the Xinerama extension for which parts exactly are visible. Then came RANDR. RANDR doesn't really matter to this issue at all. It just made dynamic configuration possible. With Xinerama, you had to configure the layout before starting the server. RANDR makes it possible to enable new screens at runtime. I don't really know what a good name for this kind of "screen" is. I think that the RANDR extension calls them outputs. >> TL;DR: I have no clue about XF86VidMode, but I guess it doesn't let you do >> what >> you want. > > Given that inversion is such a simple and basic operation, I wonder > if there's likewise a simple solution (I already tried to flip over > my monitor cable, but it won't fit ;). What exactly do you mean by "inversion" anyway? My only guess so far is that you want to inverse colors (black becomes white, white becomes black, gray stays gray), but I only guess this because of xcalib. If I understand this correctly, then I didn't even know that X11 can do so. I never heard about xcalib either (and I haven't ever built and run xcalib).
