For the very first time, I did not do a clean install: I used the dnf system-upgrade method successfully. I notice, after a few hours of use, that:
- Plasma on Wayland results in a black screen. First, the desktop background appeared, then it went to black as a Korganizer to-do appeared that I dismissed and then the screen went black again. After a long wait, nothing happened. The mouse pointer worked, but no plasma desktop.
- Plasma on Xorg works as in Fedora 29, when doing a fresh boot. However, when resuming from suspend, a black screen results, requiring a reboot. I have only tried this one time so far, so I do not know if it is repeatable.
