Black screen after installing CUDA, UBUNTU 20.04

Hi can anyone help me please?

UBUNTU 20.04, kernel 5.8.0-55-generic

20gb of RAM, 2gb Nvidia mx150, Intel Core i7-8550U.

I’m also getting this message when trying to run a model: "RuntimeError: CUDA out of memory. Tried to allocate 20.00 MiB (GPU 0; 1.96 GiB total capacity; 2.00 MiB already allocated; 9.50 MiB free; 4.00 MiB reserved in total by PyTorch) "
