Kubuntu 26.04 Resolute Raccoon review - Surprisingly nice

Good news until 2036! Here's my detailed review of the Kubuntu 26.04 Resolute Raccoon LTS release, tested in a dual-boot configuration on a laptop with AMD Ryzen 5 processor and integrated graphics, including live session, installation, post-install use, Wayland and X11 sessions, major differences between the two with still favorable functionality and performance in the X11 desktop, package management changes, various improvements in the Plasma environment and KDE software, hardware compatibility, power management, resource utilization, day-to-day use, customization, some problems and bugs, and more. Enjoy.
