a week or so ago i upgraded to ubuntu 18.04 from 16.04. i do not think the protonmail bridge problems have anything to do with this, but in any event it brought a lot of plasma, etc., stuff that i do not want. i see that i have an application -- looks like kcontrol, superficially -- to configure sddm. i am using tdm.
is there a decent recipe for the removal of kde/plasma stuff? i suppose it's worthwhile to keep gnome (or something) around in case for some reason i can't get into tde, and of course there are gnome/gtk apps i use under tde. but it seems as if the upgrade brought me a load of stuff that i don't want, and i'm not sure that it plays nicely. i can do a search on "trinity" of course, to find tde packages, but i don't know of any search term that limits the results to non-trinity kde applications and libraries.
You may be able to use something along the following lines:
$ aptitude search '?narrow(~i~n(kde|qt|plasma),!~V4:14.0.5-0)'
"From all the available versions of all packages, narrow the selection down to installed ones (the ~i term) with names containing kde or qt or plasma (the ~nregex term), and from those filter those whose version does not match the current Trinity release version."
The results marked with A in the second column were automatically installed so focus on any that don't have this marker. "aptitude why <package>" may help here.
Hope this helps, aptitude search terms can be tricky but are also pretty powerful.
