I am currently using FVWM with Xinerama and I am very happy of the overall experience. The only problem I found is related to my multi-monitor setup. I have a 3 monitor configuration using Xinerama, which I enabled in the WM through the option
Xinerama On XineramaPrimaryScreen 0
What I have noticed with this setup is that using the default placement style for the windows i.e.
CascadePlacement, the windows tend to be placed in the current monitor I am using (unless this is overrided by the application itself). The only problem I have is with the style
PositionPlacement Center, which instead of placing the windows at the center of the current screen, it places them at the center of the 3 monitors. Is there a way to place a window relatively to the current screen rather than relatively to the geometry of the 3 screens?
