The way I'm Disco testing. I'm a penguin, you know what I mean, and I test my lil' distro on the Tuxwalk. I've written a long, thorough, enthusiastic review of Kubuntu 19.04 Disco Dingo, tested in a multi-boot configuration on a laptop with UEFI, GPT and 16 partitions, covering live session, installation and post-install usage, including look & feel, network connectivity - Wireless, Bluetooth, Samba sharing, printing, multimedia support - HD video and MP3 playback, smartphone support - several Android devices and Windows Phone, KDE Connect, partitioning, slideshow, package management and updates, applications, resource usage, performance and responsiveness, hardware compatibility, suspend & resume, battery life, customization, many improvements like visual polish, browser integration and Vault privacy, small problems, other observations, and more. Enjoy.
