With a Debian 11 box with two GTX 680 I am unable to get them working. The problem occurred with upgrading from debian 10 to 11 and, from namd 11 to 12 (/NAMD_Git-2021-11-27_Linux-x86_64-multicore-CUDA)
nvidia-driver 460.91.03-1
linux-image-amd64 5.10.84-1
linux kernel 5.10.0-10-amd64
Error when trying a minimization:

I have also reconfigured the xserver, at no avail.
I have noticed issues about namd12/nvidia on the web, apparently unresolved.
Thanks for advice
