The release notes explicitly state

CUDA 11.1 Update 1 is a minor update that is binary compatible with
CUDA 11.1. This release will work with all versions of the R450
NVIDIA driver.

and therefore I downgraded the driver dependency ...

Great job NVIDIA if that doesn't work as documented.

@bluca, @ginggs: Can you verify that 11.1.1 does not work with 450.xx ?

Bug#976605: nvidia-cuda-dev 11.1 in 'testing' works with nvidia-driver 455.45 ; 'testing' has driver v 450.x

Package: nvidia-cuda-dev
Version: 11.1.1-2
Severity: important

Dear Maintainer,

You likely laready know this, but the version of nvidia-cuda-dev in testing
needs nvidia driver > 455.xx ; I've installed 455.45 from experimental, and
verified that cuda is working properly.

If the 450.xx driver from testing is installed, cuda applications fail with
cudaError_t 999 'cudaErrorUnknown' (which is confusing)

Thanks for all you hardwork here.  First time poster, longtime fan etc.
