    If you are using nvidia drivers, before booting from whatever entry
    you use in the grub menus, edit that entry and check if the
    "nouveau" driver is black listed in the kernel options and if so
    remove those blacklisting options, and then boot with those changes
    to see if that causes the desktop to load. This issue appears to be
    the same issues I get when the nvidia drivers are not signed, this
    is assuming secure boot is active.
    Also just to eliminate this as being a potential issue, when you
    edit the grub entry, check if after the kernel statement there is a
    statement to load the initramfs, as grubby (assuming this is still
    what is being used to build the grub menus on kernel updates) still
    has the tendency to not add the initramfs statement into the grub
    menus for the new kernel.
    
    regards,
