Their recommended method of installing cuda includes a 64-bit version, but not a 32-bit version. Nvidia's cuda packages are marked as incompatible with debian's nvidia-driver-* packages, so installing it uninstalls the 32-bit version. As a result, I need to choose between steam (which uses the 32-bit graphics library) and an updated cuda version (since Ubuntu 20.04's repo is pinned at 10.2).

Install the cuda-toolkit- package instead of the cuda- package in that usecase.
