Ubuntu 18.04 3D acceleration on VirtualBox
I installed Ubuntu 18.04 on VirtualBox and then set the 3D acceleration ON and when I try to start it, it shows and stays like this:
It worked fine with Ubuntu 16.04 and 17.10 but doesn't work with 18.04. I have Windows 10, Nvidia GPU, latest Virtualbox and drivers. I'm using GNOME with Xorg.
Solution 1:
Using the .iso provided in the Ubuntu repository (https://packages.ubuntu.com/bionic/all/virtualbox-guest-additions-iso/download) resolved this issue for me on Virtualbox 5.2.8. On Windows just download and extract the .iso using 7zip or similar.
