The Subject pretty much sums it up. I'm trying to figure out how to enable Dark Mode on VirtualBox 7.0 on a Ubuntu 22.04 host. On a Windows host, if you go into Preferences, there is an Interface selection in the left-hand column, and you go there to enable Dark Mode, but in Linux host, the Interface item is not in the Preferences menu.
Is there some other way to enable Dark Mode?
