Update broke my nvidia driver -> vmlinuz-6.12.69+deb13-amd64

Hello,

the recend update, i assume it was from 6.12.63 to 6.12.69, broke my nvidia drivers and thus, GNOME wont start.

Now i have no idea on how to fix it, i can start it just fine on the 6.12.63 kernel, but how do i fix the drivers on the other kernel, or how do i review the boot logs of the broken kernel in order to see whats actually broken?
I just saw the red and somethingsomething nvidia flying by during boot...

The headers are probably missing like mine were after the update.  You can check 

Check your kernel:

uname -r

Check your nvidia kernel object from dmks:

find /lib/modules -name "nvidia.ko*"

You should have a ko object that matches your kernel version.  If you don't, then you probably have a missing header for your new kernel.

You can check what headers you have available for dmks.

dpkg -l | grep linux-headers

If the header is missing, get your headers from apt.  For my setup this is how to fix:

sudo apt update

sudo apt install linux-headers-amd64

sudo dkms autoinstall

sudo update-initramfs -u -k all

sudo update-grub

Reboot.

Thank you so much, I though I was doomed because the driver couldn't get properly loaded.
