First, you might try booting an older kernel to see if that runs for you. Your bootloader such as grub might help you pick an old one.
The older kernels are actually combinations of kernel + initial ramdisk that contains the version of your graphics drivers that were being used at that time. It could be a way to test the hypothesis.
Hmm, interesting. That tells us that it’s not actually a problem with your graphics driver or kernel version, and given that it was working on this version before, I would think some aspect of Xorg configuration, your graphics hardware has an issue, or your installation in general has been corrupted when it tried to upgrade.
You might try to detect corruption by using a tool like debsums to check for any obviously corrupted files.
What’s the state of your debian packages I wonder… does something like apt-getupdate or apt-getcheck highlight any problems with the state of installed packages that could point to a failed upgrade?

Same error on older kernel
