From the gnome shell cheat sheet

Switching to and from the overview

Hot corner - moving the mouse pointer to the top left corner of the screen will take you to the overview or back to the desktop.

---------------------------------------------------------------------------------------

Since applications particularly vim always start in the top left corner
I was constantly triggering the hot corner accidently. I looked around and found
this hack on a unbuntu forum.

---------------------------------------------------------------------------------------


For 11.10

edit file /usr/share/gnome-shell/js/ui/layout.js Find this code:

this._corner = new Clutter.Rectangle({ name: 'hot-corner',
width: 1,
height: 1,
opacity: 0,
reactive: true });

Change reactive: true to reactive: false and it will disable the hot corner but still allow to activate the overview screen by clicking the Activities button or by pressing the Super (Windows) key.

Here is a funny follow-up.

My F16 system crashed when it attempted to start Gnome today ("Oh no"). I was looking at logs, booting from LiveCDs, and everything checked out. I was downloading F17, figuring that a reinstall was required, when I looked at /var/log/gdm/:0-greeter.log and saw that it was reporting a syntax error in layout.js. Yep, I had deleted a comma when making the modification, and even forgotten that I had made a modification. Easy fix that left me feeling both dumb and smart.
