For whatever reason (old config, or nvidia unreasonable default) the new
driver got installed with `PreserveVideoMemoryAllocations=1`, which
without additional nvidia services doesn't work, and so suspend breaks.
To fix:
```shell
echo 'options nvidia NVreg_PreserveVideoMemoryAllocations=0' | sudo
Installed nvidia drivers
`sudo apt install nvidia-driver-470 --install-recommends`
suspend broke. Did `sudo prime-select on-demand`, but no luck.

Reverted to the mainline kernel and hwe:
`sudo apt install linux-generic-hwe-20.04 --install-recommends`
suspend still works

Sorta solved it.
So, after all the above shenanigans `sudo pm-suspend` finally started

Decided to get rid of nvidia just in case. Didn't help.

sudo apt remove --purge '.*nvidia.*'
sudo apt reinstall --install-recommends linux-generic-hwe-20.04

While `apt dist-upgrade` to

`sudo apt install nvidia-driver-` (check in GUI "Additional Drivers",
mine is `430`)
everything works. Even the screen layout wasn't broken.
Thx to Dmitrii!

Dell Precision 5520 freeze cuz of Nvidia confirmed.
`sudo apt purge 'nvidia*'` solved it. Let's see what happens after I install it
again.
