Hello NMGLUG, I've got a two-day old install of Debian 10 with KDE Plasma desktop on a brand-new 1TB SSD in a two or three year old 15" HP-Notebook with an AMD CPU. This installed via Calamares running from a live, non-free firmware iso, checksum and signature file verified. Mostly so far everything seems robust and beautiful, but there's been considerable pathology with setting up the panels the way I like. Right-clicking on an application in either of the main application menus (I have a cascading menu in the upper panel, and the default menu in the lower panel) *should* show and permit the option of installing a one-click launch icon on the associated panel--but sometimes it does, and other times it doesn't. Also, I had a dictionary widget in the upper panel that was apparently missing one of the supporting files for some reason. In association with a desktop crash, hard powerdown* and/or my eventual removal of the widget, the error message somehow became permanent. See attached screenshot. Any suggestions for how I might best attempt to repair this? Thanks, Tom *'ctrl-alt-esc' will kill Plasma (but leave application windows running, presumably because they run in different threads) but I don't yet know how to restart Plasma from the terminal, and for some reason there is no 'shutdown', 'reboot' or 'halt' command installed.
