Thanks Alex.

This time after I moved the raven_dcmu.bin file, I ran the following to update
the initramfs image as root:

dracut --kver 5.0.6-200.fc29.x86_64 --force

This time:
1. The black screen with the horizontal line of pixels appeared, but for a
split second, and then things started working like normal.
2. I was able to log into KDE Plasma like normal.

I did a quick suspend/resume and that worked also (although there was a split
second of scrambled pixels).

Does this mean that there's something wrong with the raven_dcmu.bin file?
