Ok I know this one is daft but I'm a relative newbie to linux so go softly on me!
I have attached an external monitor to my acer aspire one running mint gloria, and after a bit of tinkering got the desired screen res on the external monitor and switched off the internal monitor
So that's fine, except that I have a green box which says "Acer 17" in the top left hand corner of every screen, which is big enough to neatly hide the left hand menu header on every program I want to use. I can't seem to find any way to get rid of it (except removing the external monitor). On the netbook, when I re-enable the internal screen, I have a pink box doing the same thing except it says "Aspire One" (or something similar, I don't have it here)
I can't drag the box away. It doesn't respond to being left or right clicked, nor to closing the display application, so I'm stumped
all help gratefully received - I'm coming to this from a background of 20 years using everything from Dos 3.3 to windows XP, but more recently OSX, so I hope I can understand any answer!
