Attached is installed packages list that ought to account for all basics: zypper se -si | grep -v lib | egrep 'mate|gnome|gtk' I've never tried mate before. I installed 42.3 fresh yesterday minimal X, then added Plasma, which works well. A mate session appears to start complete, but nothing I try opening has any window decorations. I opened Firefox, but mouse clicks in its UI do nothing, and I can't even close it using Ctrl-Q. The show desktop button said there was no window manager running, so I installed TWM, but it didn't help. I've found no mate bugs open on boo that include strings decorations and mate in comments and/or summary. Is a new bug filing indicated here for a missing WM requirement? Which WM(s) can mate use? How could requirement for a WM be missing for such basic functionality to be absent? -- "The wise are known for their understanding, and pleasant words are persuasive."
