On my Dell Latitude 5590 laptop fedora freezes as soon as the screen is locked and blank (turned off).
This happens almost deterministically, about 95% of the time. This issue also keeps me from putting my computer to sleep, as I can not get it to work again. The only thing that helps in this situation is to press the power button for several seconds to turn the computer off completely and then start again.
So, this problem is quite annoying and I would like to debug it, but I do not know how.
I looked at journalctl -b -1 to see the last messages before locking the screen, but I do not see anything useful there. Where else could I look?
