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.

After upgrading to VBox 5, it seems that VBox perceives monitor1 as monitor 2 and monitor2 as monitor1. Upon guest startup, 1 window opens at first and XP starts booting. After a while, when switching to graphical environment (during the XP boot process, just before the login screen appears) a 2nd window appears and the XP boot progress is shown in that window (the 2nd instead of the 1st). After that, the guest OS seems to treat the 2nd VBox window as the 1st screen and vice-versa. I enabled the mini-toolbar and set the 1st virtual screen to use host screen 1 but instead it used host screen 2. If VS1 is set to HS2, it works as intended but then if the guest is shut down, the external monitor is plugged-out and the guest is restarted, nothing is shown because in the laptop's monitor, the 2nd VS is supposed to be shown.

The ""Display"" of the guest shows as monitor #1 the laptop monitor and as #2 the external (i can tell from the different resolutions), however the contents of monitor 1 are shown in #2 and vice-versa.

=== MY SETUP ===
A laptop (15"" 1600x900) with a large monitor (24"" 1920x1200) as secondary monitor. I would run a Win guest on the large, secondary screen in seamless mode, so my Cinnamon taskbars & menus are on my laptop screen, my Win7 bar is on the bottom of my 2nd monitor.

=== THE PROBLEM ===
As of 4.3.18 the seamless mode mimics the height of the primary monitor (900px) though taking the whole width. Fullscreen mode still works as expected and takes up the whole secondary screen. 

More oddly, in seamless mode the 900px frame is positioned somewhere in the middle of the screen giving my a flying taskbar and VBox Toolbar.

I always faced a problem that the VBox Toolbar menues appears with a vertical offset to the actual toolbar hover (something like 300px below). But I think this is rather a Gtk issue which I can tackle.

Guest: Windows XP SP3

Host system is dual-head (two 1680x1050 LCD panels), Compiz disabled (by selecting ""None"" for Visual Effects in the Appearance Preferences panel).

VBox is configured for 2 virtual monitors. Windows reports 2 monitors as it should, and is configured to extend desktop onto the second monitor.

I normally run this VM in seamless mode. Works well most of the time. Sometimes when I move or minimize a guest window, there is a rectangular area left behind (same size as the moved/minimized guest window) showing the guest's desktop background. This area will cover up host windows if the guest window was on top of them.

This does not happen all the time. Seems to happen more often on second monitor, but does happen on first monitor sometimes.

In order to recover, I usually have to switch out of seamless mode and back in. Sometimes moving around other guest windows or clicking in another guest window will fix it.

5816	Reserve the guest OS taskbar space on the host OS desktop in seamless mode		enhancement	2009-12-21T08:23:27Z	2010-02-23T13:58:13Z	2010-02-23T13:58:13Z	"I think this will be useful for those who want the guest to work seamless with the host OS.

In the seamless mode, When a host application is maximized, it will cover the guest OS taskbar. If I want to use guest application, I have to minimize the host application to make the guest taskbar show up. So there will be a lot of unnecessary mouse clicks and movement, if I have to do much copy/paste work between guest and host.

Now, I walk around this problem using the HSI(Hawkeye ShellInit), a small tool that can create any number of margins on the screen that maximized windows won't cover.

I think this can be easily implimented in the Virtualbox. The guest additions gets the guest's taskbar position and width, then sends this imformation to the vboxmanager. The vboxmanager performs the same function in seamless mode like what the HSI will do. "	kidault

I cannot even move a desktop icon around unless I first ""minimize"" the guest or switch it out of seamless mode.

I have observed this with all releases since at least 2.0.  I am not trying to drag items between guest & host--this is regarding only the host's desktop, icons, and files."	bqbauer

When switching on seamless mode, vbox hides and I see black screen, (no any output), but I can press Home+L - and return to previous mode."	Maksim Melnikau
2570	Seamless mode with Vista host doesn't work correctly with Sidebar turned on	VirtualBox 2.0.4	defect	2008-11-05T20:24:35Z	2009-05-04T16:34:53Z	2009-05-04T16:34:53Z	"Using a Vista host with the Sidebar enabled, a Windows XP guest in seamless mode isn't cropped properly.  All window cropping is shifted to the left 2 pixels, such that a windows shows 2 pixels of the background on the left and is missing 2 pixels of the border on the right.

The problem disappears when the Sidebar is closed."	Chris Thompson
