Installed CentOS-STREAM 8 ON A QEMU/KVM virtual machine. Initially the
reboot went only to a blank display. Editing the grub menu to give a
terminal boot was successful.
Succeeded to get a graphical screen with xinit and a terminal to
explore the options. Was able to install xfce for a graphical desktop
but gnome fails. The display managers gdm and sddm both fail with a
blank screen with the mouse cursor. The others lxdm and lighdm don't
show as being available.
How do I get the session to start properly?
