Re: [gentoo-user] KDE4.6 with two monitors does not respect boundaries/edges between them

This might help narrow the source of the problem down.

This doesn't affect my nVidia card [GeForce 8600M GT] on any version between 
4.3 and latest 4.6 in the tree, so I suspect your drivers.

Snap to the edge between two monitors works here.
An unmaximized window always maximizes to fill the monitor it is on.
An unmaximized window that is partly on one monitor and partly on the other 
does a neat trick when maximized - it fills the monitor that held the bigger 
fraction of the window.

All this neat goodness works on both nVidia driver and nouveau, straight out 
the box, no fiddling required
