Dell desktop computer screen won't come back after power-save sleep. I have been running Fedora/KDE for years on this machine. This is the 2nd machine I have had this problem within 2 weeks.

I did an upgrade in place from Fedora 33/KDE to Fedora 34/KDE. The problem started immediately after that upgrade.

Here are some lines from the messages log that may be pertinent.
