After I open my Ubuntu 18.04, some app and folder icons are colored gray. I do not imply greyed-out however coated with a darkish gray overlay. (I can see a little bit orange peeking out on the tops.) It isn’t simply the desktop icons, however a lot of what’s often orange (e.g. the software program updates progress bars). I lately tried unsuccessfully to put in or allow some apps within the terminal, not realizing what I used to be doing or what I’ve completed. (I often get assist with these items from folks rather more educated than me, however am currently alone.) Not realizing what I did, I do not know if it is a good suggestion to simply transfer to trash these apps on the desktop it appears I will not be utilizing (like ARChon Packager Supervisor and android-studio), however the ‘residence’ folder I placed on the desktop and have been utilizing has the identical look. Thus far, all the things appears to operate as common, however I am involved I am being advised one thing I ought to know that I do not perceive. Is there one thing flawed right here that needs to be attended to? (I hope I haven’t got to return within the terminal and use instructions to reverse my errors.) Or ought to I simply ignore it so long as there is not any obvious downside?
