This is a regression in Ubuntu 20.04. Anybody who has nvidia-driver-470 and updates to kernel version 5.11.0-34-generic will experience black screen. A temporary walkaround is to log in to a TTY (Ctrl+Alt+F2) and remove all nvidia-related packages: sudo apt purge nvidia-driver-470 nvidia-kernel-common-470 ... You can just type sudo apt purge nvidia and hit ↹...

I'm experiencing the same issue on my laptop. So far, I've found this link on the ubuntu forum (since elementary hera is based on Ubuntu 18.04): https://askubuntu.com/questions/1038723/slow-recovering-from-lock-screen-ubuntu-18-04 Also, found those two bugs registered at Ubuntu's Lauchpad: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1832812 ...

I get the same thing but mine had to do with adding a 5600 xt and the radeon drivers in 5.3 not working. Installing 5.4 fixed the issue. Too do this boot to 5.1 and install ukuu and use it too install 5.4 I haven't tried 5.5.
