Something like that. But, my fault, because I did not say I was speaking about the physical console (I do not know the name; while on the GUI, press Cntl-Alt-F1; then, you'll be in what I'll call "the physical console") this has to do exclusively with the hardware. I mean, the video controller makes the CRT electron beam to increase its intensity. As a result, characters sent the CRT are seen brighter.
Perhaps the word CRT is introducing confusion here. Shall I say computer monitor? Or perhaps that part of the console which is not the keyboard.
Another way of making myself a little clearer is, may be, this: press Cntl-Alt-Fn, 1 <= n <= 6 (X may have been started from some of these, so you won't be able to use it), login if necessary, type 'vim reina_isabel_la_catolica'. OK. If your settings for vim are the same as in my case, then pressing the 'I' key and afterwords typing some text, you'll see what I meant in post #1.
