Fresh install in my case is the Manjaro GNOME .ISO in VirtualBox. Works well so far with my experimentation/testing. I didn’t install an office suite or a few other things I won’t need for VB testing.
The only issue I’ve had is I found it locks up after a while in (U)EFI mode but that seemingly isn’t a Manjaro issue rather a VirtualBox problem (same thing happens with EndeavourOS and Manjaro KDE).
Also my issue of being a Gnome “Virgin” and as yet have no idea how to find my way around it! Totally alien to me. (Installed it to see if might be useful for “helping” on here).
