Step #5: Multiple monitors, full screen, drivers and resolutionĪnother possible reasons for blank images of your machine might be: Multi-monitor Setup Change it to default in case it was changed:.In this case you need to disable Hyper-V: Icon for green turtle will be shown in the notification area of VirtualBox as shown below. For example if Hyper-V is enabled but not able to use the load of the Virtual Machine will be slow. Since VirtualBox 6 there are other changes which might cause blank screen and new notifications. So if you are running VirtualBox 6 and you have VBoxSVGA as display controller than you can try by increasing the video memory(step 1). Many complaints are reported for problems related to Graphic Controller which can be changed by: About VirtualBox - then you will see something like: 5.2.34 or 6.0.14.You can check the version of the VirtualBox by: This option works only for VirtualBox 6 (the option is not present in VirtualBox 5 and before). Step #3: VirtualBox Change the Graphics Controller Start VM and the problem should be resolved.Increase the Video Memory to 128 MB (or something higher than initial 16 MB in my case).Create virtual machine with VMware player 15 Linux Mint/Windows.If you plan to play games especially you can check these links: If you need more memory for your Virtual Machine you better go with VMware Player because it has limit of 2 GB of Graphics memory while VirtualBox is 128 MB. So after quick research I found that virtual memory will cause display issues. This can be done by:Īfter reset to the initial folder the problem was still present. The only change I did for VirtualBox was to change default folder where the machines are stored(between the creation of the working and not working machines). Step #2: VirtualBox Guest Low Video Memory 00:00:42.162769 GUI: UIMultiScreenLayout::update: GUI/AutomountGuestScreens is disabled.It highly depends on the VirtualBox version and the hardware - so I recommend for you to test next steps in order to solve blank screen. Which indicates possible problem with BIOS. Or messages like: 00:00:01.613729 HM: HMR3Init: Falling back to raw-mode: VT-x is disabled in the BIOS for all CPU modesĠ0:00:02.046662 Full Name: "Intel(R) Pentium(R) CPU G4560 3.50GHz" If I escape the full screen the VM starts working again. In this case I can see only the last screen shown from the VM before the full screen. The logs above are taken when the guest VM Linux Mint has low Video Memory and full screen is activated for resolution: 2560x1440. The logs will help you to find what is causing the problem no matter of the VMs - Ubuntu, Linux Mint or Windows.įor example: 00:01:36.555713 GUI: UIMultiScreenLayout::update: GUI/AutomountGuestScreens is disabledĠ0:01:36.565931 GUI: UIFrameBufferPrivate::Notif圜hange: Screen=0, Origin=0x0, Size=2560x1367, Sending to async-handlerĠ0:01:36.567618 OpenGL: Set 3D content scale factor to (10000, 10000), multiplier 10000 (rc=VINF_SUCCESS)Ġ0:01:36.567663 OpenGL: Set OpenGL scale policy on HiDPI displays (fUnscaledHiDPI=0)Ġ0:01:36.569086 GUI: UIMachineViewFullscreen::adjustGuestScreenSize: Adjust guest-screen size if necessary.Ġ0:01:36.569101 GUI: UIMachineView::sltPerformGuestResize: Sending guest size-hint to screen 0 as 2560x1440 if necessary The first thing you need to start when you have problems with your programs and VirtualBox in this case are the logs. Ubuntu Linux add VirtualBox Guest Additions Step #1: Check logs of VirtualBox for errors

If not you can follow how to install them in this article: It's good idea to ensure that guest additions are installed for this Virtual Machine.
Some of them are related to dual monitor setup, others to incorrect graphic settings. So after short investigation of the problem I found several possible problems and solution which I decided to wrap up in article. But again - successful install followed by black screen after boot of the machine. I decided to install the older working version and see if the problem is solved. No matter of changing or resizing the window. I created new VM for the latest Linux Mint 19.3 which was installed successfully but after reboot the screen was black.

I have VirtualBox with two working virtual machines(VM): Windows and Linux Mint.
