15499	seamless mode works only on laptop screen	dovholuk		"I have found that using seamless mode in Fedora and Ubuntu will result in the screen going seamless on the laptop's display only. I have three screens - the laptop screen and two external monitors (via a docking station) in that order:
    laptop screen <--> lcd panel 1 <--> lcd panel 2

I have set my ""middle"" monitor (lcd panel 1) to be the main window however no matter what I do I've not found a way to go seamless and have the seamless display on the monitor of my choosing.

An interesting note is that the desktop manager ""cinnamon"" - DOES work properly. I can move the non-seamless window to whichever screen I choose, use HOST+l to go seamless and it'll be seamless on the monitor that the non-maximized guest OS was on. (this does have some interesting quirks too but it works > 90% of the time pefectly)

It's been a bug for as long as I've used virtualbox (a long time) and I've seen the bug all through the later 4.x and now in the 5.x product.
