Even if the PC has multiple outputs - they are mapped to monitors in Xorg. Dual-head cards - can be using 2 screens or two cards in PC etc, however I never had to use one. Your statement is partially true regarding positioning. It is true only if the coordinates are falling outside of the active monitor. I still think you or we are mixing up the terminology here. I now checked few documents again and find out that my understanding was also partial https://wiki.archlinux.org/index.php/multihead Note: The terms used in this article are very specific to avoid confusion: Monitor refers to a physical display device, such as an LCD panel. Screen refers to an X-Window screen (that is: a monitor attached to a display). Display refers to a collection of screens that are in use at the same time showing parts of a single desktop (you can drag windows among all screens in a single display). I also do not understand your problem completely. For example I have a monitor attached to two pcs. if I switch to the other pc and switch back - programs are still where they were. If I unplug or disable the monitor via xrandr. Programs are moved to the active monitor and resized/squeezed whatever. I have no problem with this as I understand that the software is trying its best to match the new available size of the monitor (resolution) etc. This is also interesting: https://nouveau.freedesktop.org/wiki/MultiMonitorDesktop/ There were a lot of interesting things around wayland. regards
