Ubuntu 20.04 suspend not working with nvidia-driver-450-server

I switched to nvidia-driver-450-server because my second monitor stopped working after switching to nvidia-driver-460. However, this switch broke suspend on my ThinkPad running Ubuntu 20.04. The laptop doesn't properly suspend anymore, and when trying to get it out of suspend it gets stuck on a black screen.
