I am running Ubuntu 18.04.03 as host and have a Windowss 10 guest(both 64 bit). Virtualbox version 6. I have guest additions installed and 3D acceleration works, but when I got to display and check the box for 2D acceleration and click okay, it doesn't save it.
As soon as I go back, it is unchecked again. Not sure what this bug is and would appreciate any help. I have been trying to fix this for quite a while.
Currently my best guess is that either...
- ... my virtualbox edition has an issue, or
- ... 2D acceleration isn't supported.
But if it isn't supported, I would have expected the CheckBox to be greyed out...
