Public bug reported: My system has been upgraded through several Ubuntu versions, and I'm now (15 Feb 2020) on a pre-release version of Ubuntu 20.04 (Focal Fossa). I've been using Unity on this system since Ubuntu's installation years ago, and it's worked fine, including when I first installed the pre- release Ubuntu 20.04 a week or two ago. I updated packages on 13 Feb or 14 Feb, however. Now, when I log in, I get nothing but a blank screen -- no window manager or desktop environment appears to be running. I'm able to open a Terminal by right-clicking on the (black) desktop and selecting "run from Terminal" from the list of options, and I can then start icewm -- but I need to use the "--replace" option because icewm thinks a window manager IS running, even though the windows have no widgets or other ways to control them. (I've been using X since pre- Linux days, so I know what X without a window manager looks like, and to all appearances, this is it.)
