Did anyone get a solution to this? I've a piece of software that only works on CentOS 8 (doesn't work on CentOS 7) and I can't get this installed due to the "Black Screen of Death" (sorry.... I had to name it).

I'm having the same issue that @m076162 had. I've tried upping the RAM to 16GB but I don't get to the login screen. Just stays on the Logo 8 black background screen. @m076162 How did you run the "yum groupinstall "Workstation" command? Cent OS 7 out of the box doesn't have a network configured within the installation. Hence you can't SSH into the box using PuTTy to configure the network and run the Yum command. Did you configure the network as part of the installation process for CentOS 8?

Edit: Just to say that I've just tried a new install of CentOS 8 and configuring the Network during the installation procedure, then I could successfully SSH into the box using PuTTy to run the suggested command. Even still, I'm still getting the black screen of death.
