snip.
X11, and X-windows in general, seem not to understand the concept of negative screen coordinates. Apple takes the (0,0) point to be the upper left corner of the main - with menus - monitor. Things above or to the left of that are negative.
X11, or something nearby, changes the coordinate zero to the upper left of the rectangle which encloses all monitors. In my case, with a monitor to the left, another to the right, and a third above my main monitor I get into a structure in which X11 wants to throw windows above the left monitor and to the left of the upper monitor. Since there is no phosphor present it is doomed to failure.
A lot of care with the --geometry options in window managers and cooperating applications helps. A - geometry option in line opening the first window manager in .xinitrc is a requirement .
In the case of a monitor being removed while running it could make a whole lot of difference if it's to the right or above the main monitor which remains.
