[Solved] VM in full screen mode always appears in host's main screen

Postby boh » 22. Jul 2019, 10:13

Hi everybody,

I have a windows host with a three-monitor setup (all of them are identical and 4K).

I run on my host a Windows Guest.

No matter what host screen I choose from the VM menu, in full screen mode the VM will always move to main host screen... which is very annoying.

I am running Virtual Box 6.0.10 r132072.

I attach the log file.

Anyone can help me with this bug?

Thanks a lot.

Why are you in such a hurry to call it "a bug"? Have you tried going in the MenuBar, or pressing HostKey+Home » View » Virtual Screen 1 » Use Host Screen 1/2/3/.../n?

Hi Socratis,

yes, I did try what you suggest.
I am sorry for my english, but that is what I meant by "No matter what host screen I choose from the VM menu, in full screen mode the VM will always move to main host screen".

No matter which host screen I select, the VM will always remain on host main screen.

I can move the vm to other host screens (I have 3 screens in total) if I do not use the full screen mode.

OK, let's try and see if we can reset some settings then. I would like to see the "recipe" of the VM, the ".vbox" file:
  1. Right-click on the VM in the VirtualBox Manager. Select "Show in Explorer".
  2. ZIP the selected ".vbox" file and attach it to your response.

Hi Socratis,

thank you for your help.

I attach what you requested (you will find a vbox file and also a vbox-prev file; they both have the same date (today)).

Thanks again
Best regards,
Domenico

Hi Socratis,

I have gone through the log file of the VM (I attach it in case you want to see it).

I think I might found the issue: while loading, the VM sees only one host monitor.

I paste in the following the relevant lines:
00:00:01.732561 [/Devices/vga/0/Config/] (level 4)
00:00:01.732562 3DEnabled <integer> = 0x0000000000000000 (0)

00:00:01.732563 FadeOut <integer> = 0x0000000000000001 (1)
00:00:01.732564 HeightReduction <integer> = 0x0000000000000000 (0)
00:00:01.732564 LogoFile <string> = "" (cb=1)
00:00:01.732565 LogoTime <integer> = 0x0000000000000000 (0)

No, that's not it, that's showing how many virtual monitors your VM has.

Please follow the following steps, exactly as I'm describing them...

Exit from full-screen, move the VM window to monitor 2, take it to full-screen again. Does it work?

If not, exit full-screen, close the VM, and enter the following command:

    cd "C:\Program Files\Oracle\VirtualBox"
    VBoxManage setextradata "Clone di PC di Casa" "GUI/VirtualScreenToHostScreen0" 1
Start the VM, take it to full-screen. Does it work?

For future reference, you should completely shut down the VM before grabbing the VBox.log.

Hi Socratis,

I followed your guidelines.

Here are the results:

1) "Exit from full-screen, move the VM window to monitor 2, take it to full-screen again. Does it work?"
When I exit from full-screen mode, the VM moves by itself to monitor 2 (no need to move it, hence).
When I take it to full-screen again, the VM moves back by itself to the main host monitor

2) "If not, exit full-screen, close the VM, and enter the following command:"...

This worked!

Thank you so much, Socratis.

Very kind of you.

Domenico
