virtualbox.org

Hi,

I'm using OS 10.14.4 with a Win 10x64 1809 VM, using VirtualBox 6.0.8 r130520.
The problem is that when the guest OS goes to sleep mode and I try to wake it up I can only see black screen and the only thing I can do is to force a shutdown.
I think it's something related to video settings as it happens only when I use as graphic card "VBoxVGA" with 3D and 2D video acceleration both checked.
If I unchek 3D acceleration it doesn't happen but guest OS becomes really slow and almost unusable.
Is there something I could change or I'm forced to use it without 3D acceleration?
I've attached VBox log at the moment when I try to wake up my VM.

Thank you

Kari

I have the same problem. This already started in version 6.0.6 and is also in 6.0.8. I can only revert back to 6.0.4 where it does not happen.

I am running a host with Win 10x64 with guest Win10x64.
It runs until I leave the vm unattended until it goes to idle black screen after some minutes. When I return the screen does not come back.

I use a keyboard combination to shut down the computer by keyboard: (Keys to shut down: WinKey+X, Arrow up, arrow up, arrow right, arrow up, arrow up, enter -> shutdown happens)
Then the VM shuts down correctly. So to me it looks like a graphics issue and the Windows is still running correctly.

As it seems that there's no solution for now, the only way I found to bypass this issue is to completely disable sleep mode in Windows settings.

I have the same issue at VirtualBox 6.0.14.

Hope this will be fixed soon.

same here, possibly OS X 6.0.14

If I boot to this:

http://releases.ubuntu.com/19.10/ubuntu ... -amd64.iso

(OS X host) and wait a couple minutes till sleep disables screen, it can never come back to life...even when I mouse over it, etc.

However on a box I have with ubuntu and guest additions installed, sleep seems to work fine there...

Update: turns out my issue was not enough RAM: https://answers.launchpad.net/ubuntu/+question/686227
