Hi David, could you try nvidia-tesla-450-driver 450.102.04-1 from sid? It is installable along the regular driver and you can switch between the different drivers with update-glx (and then reboot to load the other kernel module and libraries).
This is just to check whether the 450 series got "broken" too with the latest version (which includes a CVE fix). Thanks Andreas PS: If it is still working fine, we might keep the tesla-450 driver in bullseye along tesla-460.
