Am in the process of testing 4 Linux Distros – Kubuntu 18.04.3 ‘Live’ USB with persistence … KDE neon ‘Live’ USB … Kubuntu 19.10 ‘Live’ USB … Ubuntu 20.04 daily build ‘Live’ USB.
Using a Sabrent 4-Port USB 3.0 Hub with Individual LED Power Switches – Can turn on a Distro to be tested by pushing individual push button switches. Can also unplug the USB hub from one test computer and plug it into another test computer. I have several 3.0 versions of this hub and a couple 2.0 versions. If too many LED lights bother you, all four of these can be turned off. I use the 2.0 versions mainly for plugging in Wi-Fi USB adapters, keyboard/mouse wireless USB, printers and USB speakers. The 3.0 version also comes in handy if you’re using a laptop very often – small and easily stored in a laptop case.
Wanted to take another look at the KDE Plasma Desktop, and do some testing before Kubuntu’s 20.04 LTS stable comes out (may also test their daily build).
