Without any text? Weird.
OK, I guess that means it's a kernel problem and not an X driver problem or anything.
Just out of curiosity: I know that system updates (and not necessarily system upgrades) leave behind the old kernel, the last kernel that you used and was "known to work", for this exact kind of situation. If you press the Esc key while booting the system up (right after the BIOS/UEFI firmware finishes loading, there should be a message that says to press Esc to interrupt the boot process), this should open up a menu of operating system choices. The default option should be at the top of the list; the default is the kernel with the graphics driver flaw. If you use the down arrow key a few times to navigate to the newest kernel option that is not labelled "Recovery Mode" and is not at the very top of the list, do the graphics work then?
I have a sneaky feeling that the old kernels are purged during a system upgrade (it's been a long time since I did an upgrade myself), but let's just see if the search is fruitful. Sometimes you get unexpected pleasures.
