The puzzle for me is that I can see no mention of it in my notes : my user is in the video group in my previous machine, but I'm quite sure I didn't add it there, so it must have been the default. Somehow, it wasn't added when I set up my present machine Oct 2015 (or something overwrote it, but what ? ). My memory is that Xscreensaver showed the 3D modules at that time, but that they disappeared in early Dec 2015 , around which time I remerged Xscreensaver & also updated Xorg-server + friends. >> If the latter, how are users supposed to know re such matters ? > I was wondering for quite some time why sddm only showed a black screen, > until I realized that the sddm user needs to be in video group too. > tl;dr - happened to me too and a solution or at least > some big error / warning would be nice. Thinking about it. Whyever would the default be to add 'root' to 'video', but not 'user' ? -- one would expect it to be the other way round. In fact, why would root ever need to use 3D for anything ? -- root sb able to do all its stuff in a raw terminal without X. Thanks again for solving both my problems so elegantly (smile). It confirms by general belief that in Gentoo, problems are skin-deep : find out where they are -- the difficult bit sometimes -- & then it's very easy to fix them. PS what does 'tl;dr' mean ? -- I've seen it in other msgs. -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
