#f40
I can finally say I've upgraded successfully to #Fedora40. It was not without hassle this time and it started with what seemed to be a system that did not even give me a prompt after #rebooting, although the update process had seemed to go smoothly and quickly. Luckily, the virtual screens were working and so I could #login to a #shell. Although #sddm didn't seem to be working, #kdm was and so I was able to open a desktop session, but only in #Gnome. There were still problems running #kde #programs such as #konsole and #korganizer as some #qt #libraries were missing. Installing those allowed the programs to run. Also, no #audio devices were being detected and so I couldn't play any clips, etc.
Today I found that #kwin was also lacking a library (#qtsensors) and so after that was installed and I rebooted the machine, I found that sddm was working again and so I could log in to the #kde session that I usually do. Also, the #sound issue was solved by removing the directory #wireplumber from ~/.local/state.
