#VIRTUAL MACHINE BLACK SCREEN HOW TO#

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.

#VIRTUAL MACHINE BLACK SCREEN DRIVER#

Gundarev said that the best option right now is to 'install an updated display driver from the hardware manufacturer.' And if a new version isn't available, 'you can workaround this by disabling the problematic driver in the device manager.I have VirtualBox with two working virtual machines(VM): Windows and Linux Mint. It looks like the fix is taking some time, but there are simple workarounds to address the problem. 'Our team has identified the issue and we are currently verifying the fix that will dynamically switch to the software renderer if the problematic driver is detected,' he had assured on June 12. Starting with WindRDP uses this data to initialize the session. Because of that, some of the old versions of the legacy display driver may report invalid data and it would be ignored. In previous Windows versions this reported data wasnвЂ™t used or verified.

#VIRTUAL MACHINE BLACK SCREEN DRIVERS#

ThereвЂ™s a known issue with some of the old display drivers.Дisplay drivers report some of their capabilities upon load. Microsoft has acknowledged this problem with the company'sВ Remote Desktop Protocol and WVD Program Manager, Denis Gundarev, saying (via MSPU): I could keep using GoToAssist but RDP over my local LAN is much faster. Finally I reverted it back to 1809 and Remote Desktop once again works. Fortunately I also have GoToAssist installed so I was able to log into the secondary machine that way and checked for updates, still no help.

I then upgraded my primary machine to 1903 hoping that would help, but no. When I access it now using Remote Desktop all I get is a black screen in the RDP windows. I upgraded my secondary machine from 1809 to 1903.
