Hi there, I'm trying to draw large scenes on multi monitor setups. I can get all screens and the resolutions of the screens via:
numberOfScreens = XScreenCount(dpy); /* Work out the sizes of the screens */ for (int j = 0; j<numberOfScreens; j++) { Screen *screen = XScreenOfDisplay(dpy, j); SIZE_X = DisplayWidth(dpy,j); SIZE_Y = DisplayHeight(dpy, j); printf("Width::%d\tHeight::%d\n", DisplayWidth(dpy,j), DisplayHeight(dpy,j)); } But how can I get where one screen is in relation to another? eg. If there are four(4) 2560x1600 monitors arranged in a column, the top screen has its first pixel at [0,0], the second monitor is [0, 1600], third is [0,3200], etc This is ok to dodgy hack, but when I move to a machine where the monitors are arranged horizontally eg [0,0], [2560,0], [5120, 0] and [7680,0] All breaks. I would prefer not to have a configuration file and would also prefer not to parse the xorg.conf file. PS. I have have temporarily confused the [0,0] pixel with opengl (bottom left - as opposed to top left for a screen. Hopefully you still get the idea). Any pointers? It appears as though xdotool appears to know this information when moving a mouse.
