My setup is two external screens connected to a docking station and the laptop screen all running (thanks, Lenovo!). I have four virtual desktops (Ubuntu 14.04, Unity). At any point I might have one to two dozens windows open, carefully organised across the virtual desktops and screens.
Now, every time I put my laptop to sleep and wake it up again (it remains connected to the docking station for the whole time), the windows are no longer where they were.
I could understand if Unity forgot the position on each desktop, maybe because it detects the additional screens after positioning the windows on the laptop screen alone. However, the windows are also scattered across the virtual desktops with no recognisable pattern: windows from any desktop may end up on any other, and on other screens as well.
What is happening here and how do I fix it?
Bonus question: do other window/desktop managers have the same problem?
