coming back to a linux laptop i haven't used in a year or so. i look up at the indicator applet tray in my MATE desktop. there is a prohibited symbol. i click on it. an empty box appears. i right click on it. i get the helpful about box that this is an indicator applet panel. i do not know what the prohibited sign means. i cannot get rid of it without getting rid of all the other applets. this is the reality of using a linux desktop
the only reason this laptop runs linux is that it's a centrino duo from 2008. linux is lightweight, but that's at the expense of not really being very good
