System is Leap 16.0 KDE. About every fourth or fifth time the system wakes from sleep, there are no graphics. The screen is black and the monitor power light blinks to show no signal. The system responds to keyboard and mouse. As a workaround, I do ALT+F2 enough times to close all the running programs, then CTRL+ALT+DEL to get the shutdown window, right arrow to select Log Out, Enter. All this is with no graphics. After a few seconds, graphics start at the log in window, and I get everything going again.
I did sudo journalctl -b, but could not find the problem. I really do not know what to look for.

How can I find what the problem is and how to fix it?
Thanks,
