Public bug reported:
After upgrading to 21.10 from 21.04 this problem started happening.
It does not happen every time I suspend, and it usually happens after
suspending for a longer time. After suspending for a longer time, it
tends to happen most of the time.
I can SSH into the computer, so it is just the display that is not
turning back on correctly.
Lenovo Thinkpad P51 with an NVIDIA quadro Quadro M1200
journalctl -o short-precise -k -b -1 contained the following messages of
interest, which I could not find in other reports:
```
