Replace fallback distro, OpenSuse with Manjaro [Arch based] XFCE. First logon will fail unless you specify a default XFCE session. Unable to erase files or change permissions on a USB flash drive. I shows me as the owner anyway. Google seems to suggest “ghost files” from a windows virus. There were various solutions, however my own solution to use the gnome-disk-utility 3.10.0 to format then create a filesystem [i think] seemed to be the easiest. Perhaps I got a virus while accessing my Windows hard drive which mysteriously failed to boot a few days ago.
