Long time readers of FCM will know that my first brush with Linux was with Kubuntu and KDE (3.5) many moons ago. I gave up on it when KDE4.0 arrived on the scene (unusable), briefly returned when it stabilised at 4.5, but left again when Plasma 5 came along as it didn't have a GUI for my graphics tablet. Well, a couple of weeks ago I decided to give the latest Kubuntu Live DVD a try. Just for old time sakes. And, wouldn't you know it, they've added the missing graphics tablet GUI! I'm not sure when it was added, but I duly installed Kubuntu 20.04.1 and it feels good to be back. I'm still not sure why they quickly abandoned KDE 4 for Plasma 5. I just hope they don't Find Full Circle on: suddenly abandon Plasma 5 now that I've installed it. facebook.com/ fullcirclemagazine One issue that I had, on installing Kubuntu 20.04.1, was that I had no sound. I tried all sorts of possible solutions. I could see (in Pavucontrol) that the sound was being produced as the little bar twitter.com/#!/fullcirclemag jumped up and down to the inaudible sound. Only after several days of head scratching did I find http://issuu.com/ my solution. It turns out my PC has two output jacks and Kubuntu had decided to switch jacks. I fullcirclemagazine only found the second jack after much crawling on my knees with a torch under my desk.
