I nearly always have multiple applications open in multiple windows across both monitors and all virtual desktops. When I lock the screen and then unlock, my application windows will move from their original position. Sometimes they are in completely random positions; Other times they seem to get the monitors confused, and rather than being in the top half of the portrait monitor they are on the top half of the landscape monitor; Sometimes it is only a new desktop, but the monitor position is the same; Sometimes it is the same desktop, but on the other monitor. Description: Ubuntu 13.10 Release: 13.10 What I expect to happen: When I unlock my computer, all the windows are in the same position on the same monitor and desktop as I left them. What actually happens: When I unlock my computer, some or all of the windows have been changed to a random position on a random monitor and/or desktop.
