Today my Tumbleweed distro upgraded to the 5.8.0.1-default kernel and on reboot video is working and I'm typing this post via the 5.8 kernel . . . . So either the ubuntu apt pre-release version of the kernel is higher up than this one, OR, there was some other package that caused the problems in the two ubuntu distros that I have installed.
Both have been rolled back to "un-pre-release" and the grub listings have worked themselves out so that the 5.4 kernels are now default . . . .
