A bit more testing shows completely random results each time the second configuration is applied. For example this picture shows the problems now occurring on the Sony screen rather than the Dell screen.
The biggest effect seen on the Sony screen in this instance included mouse position offset where the mouse is registering in a different place from where the pointer is. As soon as I was able to restore the original configuration everything works fine. Attachment showing the messed up display. The computer had just been restarted and there were no programs running, so the stuff displayed in the top section of the screen was not from any running applications. ** Attachment added: "IMG_20170716_170942.jpg" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1704616/+attachment/4915453/+files/IMG_20170716_170942.jpg -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1704616 Title: Display settings mess up when screens rearranged in xfce-display- settings Status in xorg package in Ubuntu: New Bug description: I have a Dell 1280x1024 19" screen and Sony 1366x768 32" screen. Due to the ports they are connected to on the video card they appear by default in xfce-display-settings in the reverse to their physical layout. On previous versions of Xubuntu there has not been any problem with rearranging the display order. On artful I can only get things to work properly if I leave the display order to the default. If I try to rearrange the display order on artful all sorts of weird things happen. The 19" screen only uses two thirds of its vertical height to display the picture, the rest is drawn as white. The taskbar disappears completely. The mouse has to be on the opposite screen to the one where you are working in order to be able to click on anything.
