[Solved] choosing Monitor for seamless mode

[karlsinn]

Hi,

Two monitors
OpenSuSE 43
VirtualBox 5.2.8

until yesterday I managed to choose the monitor for the seamless mode by simply moving the main window of the client to the one I wanted the main window to be and then activate seamless mode. Since yesterday, both virtual screens open on the same monitor. Nothing I do changes this even using the VirtualBox menu that appears in seamless mode.

I tried to update VirtualBox => no change
I turned off the 2nd virtual screen => main virtual screen always opens on the same host monitor

What can I do?
thx,
Karl

Right-click on the VM in the VirtualBox Manager. Select "Show in Finder/Explorer/Whatever". ZIP the selected ".vbox" file and attach it to your response.

Since yesterday, both virtual screens open on the same monitor.

Not according to the recipe... It's clear the screen 0 goes to monitor 0, and screen 1 goes to monitor 1:

<ExtraDataItem name="GUI/VirtualScreenToHostScreen0" value="0"/>
<ExtraDataItem name="GUI/VirtualScreenToHostScreen1" value="1"/>

Anything else that may have changed in your setup? You can also try it with full-screen, and secondly you can change which screen goes to which monitor from the menu or the mini-toolbar.

Interesting, the information about the second virtual monitor is still in the file as I had deleted the 2nd virtual monitor.

I have tried in fullscreen (HOST+F) and indeed in fullscreen I can change the monitor on which the box is displayed by selecting the monitor I want in the menu of the mini-toolbar.
Still, in seamless mode it's not working. I can click on both monitors in the list but nothing changes.

I have moved the whole computer yesterday from one corner to the other. In the new location I tried to connect one of the monitors with a HDMI cable which didn't work at all, so I switched back to the old cable. And because of my new seating position I have moved the XFCE4 menu to the other screen. Can't think of any other change and these changes shouldn't create my problem.

Any ideas what I can do?

FYI: I tried to create a new box connecting the same vdi. Doesn't change the behavior

Hi,

by chance I figured that I have to move the window of the VirtualBoxManager , the first Screen of the VirtualBox and the mouse to the monitor where I want the main virtual monitor to appear. Then things work out as usual.

thx for the help,
Karl

Hmm... interesting. I never made the "connection" with such a behavior, I've always used my primary monitor as my primary screen I guess...

Glad you got it going. And thank you for marking the topic as [Solved]...
