Dumping a bit more debug log before I forget:

I disabled NVIDIA from the software & updates. If I try to suspend:

- it immediately wakes up into lock screen
- I can't login anymore: after password, goes into black kernel log screen as in boot

That was in Wayland, the new default. So I blacklist wayland, reboot to X11, and now when trying to suspend:

- it immediately wakes up into lock screen
- but I can login

- https://askubuntu.com/questions/1133919/ubuntu-18-04-2-immediately-wakes-up-from-suspend

Notably https://askubuntu.com/a/1363662/52975 says CUDA might still be a problem! So I now purged Everything from NVIDIA, I noticed that I had nvidia-opencl-dev:amd64 installed ii, and the graphics stuff installed rc, and immediately after purge suspend works again on X11!
