Simple problem with gnome-terminal

When I am in the console (gnome-terminal) and press the key backspace some times, the screen puts black and returns immediately to normality

(my video card does not have good support in linux but I do not believe that it is the problem. I use unchrome pro IGP, ubuntu 7.04)

This also happens to the key esc.

Something peculiar is that if I press repeated times all appears “Display 2020 possibilities? ”… (it must be a secret that I do not know). If now I press yes it appears a list of commandos

(use a translator. sorry if my English is not very good. greetings)

In mozilla firefox and other programs happens the same.
For example: in some Web. ctrl + f (find). I write average and when pressing the space, puts black the screen and returns immediately to normality. This returns to spend when pressing repeated times space

Hello Diego,

Are you maybe using Compiz, Beryl or Compiz Fusion?

Hello Saša. I Use only gnome (without beryl nor nothing of the sort

Hello Diego,

Could you try to rephrase some parts of your report? I'm having trouble understanding some of them:

"When I am in the console (gnome-terminal) and press the key backspace some times, the screen puts black and returns immediately to normality"

"In mozilla firefox and other programs happens the same.
For example: in some Web. ctrl + f (find). I write average and when pressing the space, puts black the screen and returns immediately to normality. This returns to spend when pressing repeated times space"

What does happen? The screen turns black? Does all the screen go black, or just the programs window?

The ESC key in Terminal is a feature. You can do the same by pressing the TAB key.
