I am trying to run the ISO of Manjaro-kde-20.1-rc6-200908-linux58, in Virtualbox, on a Kubuntu 20.04 host.
I see text on the screen at the beginning of the boot process, but then it goes blank, and eventually shows this error: “Could not sync environment to dbus.” The error message shows in a white balloon in the upper left corner of the screen, and there is a button where I can click “okay”. If I click it, it stays at a blank black screen.
I created the VM with default settings. Then I tried enabling 3D acceleration, but it didn’t help. The graphics controller is VMSVGA.
