Gnome 3: Howto Turn off HotCorner / Auto Mouse-Over Feature

If you are like me you will find that accidentally hovering over the Activities button in the top left corner will bring up the dash board, and it gets really annoying especially when browsing with Google Chrome and you move the mouse a bit too far to minimize or click back, and it pops out.. Just annoying to me. Thought others might find this useful:

open a terminal:

1. su

2. mousepad /usr/share/gnome-shell/js/ui/panel.js
(or subsitute mousepad for your preferred editor e.g. vim, gedit, nano, etc)

3. Scroll down to these lines:

this.actor = new Clutter.Group({ width: 3,
height: 3,
reactive: true });

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

4. Change the line that says reactive on both from true to false so that it looks like:

this.actor = new Clutter.Group({ width: 3,
height: 3,
reactive: false });

this._corner = new Clutter.Rectangle({ width: 1,
height: 1,
opacity: 0,
reactive: false });

5. Save the file and then Logout of Gnome.

6. Log back in and enjoy the disabled hotcorner!

Had to sign up with this forum just to be able to post a BIG THANK YOU for this post. This has been the most irritating feature with Gnome 3, and the possibility not be able to disable it have been very frustrating.

So thanks once again! Now I just hope we are given the ability to have more horizontal desktops. Then I think I'll get along with G3 pretty well. =)

I use cairo dock for my horizontal dock and I also removed the ugly extension from the gnome shell for that vertical dock as well.. Makes the desktop look and feel about like OSX. But I am glad you found this post helpful!

Nowadays the file to edit to accomplish the above seems to be (Fedora):

/usr/share/gnome-shell/js/ui/layout.js

Cheers!

Big thanks to both kataklysm & ronin94!

Just switched to Ubuntu from Windows 7 and currently using Gnome 3 which is fine, but this was really driving me loopy. Much better with click functionality.

Cheers!

There's an extension to accomplish this, called "No Topleft Hot Corner." Go to https://extensions.gnome.org/extensi...ft-hot-corner/. To install it, you just click "on" at the top of the page next to the name of the extension, and magic happens. You can turn it off again using gnome-tweak-tool (or, I assume, back on that web page).

At the time of this thread being created, there was no extension for it. However the method I have mentioned still works. Thanks for the update on the extension. It's still good to know how to go in and turn it off by hand instead of relying on someone else's javascript to accomplish the same thing blindly
