I am running Ubuntu Gnome 14.04 LTS, Gnome Classic and I want to turn off the auto-maximizing of windows that occurs when I drag a window to the top of the screen. I admit to being confused about the functionality and meaning of compiz, metacity, gconf-editor, etc., but I have tried to follow the instructions that worked for other people with this same problem, and none of them has worked.

I tried using Compiz Configuration Settings Manager (CCSM) to change the Top Edge behaviour from "maximize" to "None" as described in Turning off auto-maximizing of windows in 14.04. I also used gconf-editor to set top_edge_action to 0, as described in How to turn off Compiz's "drag to maximize" behaviour? . I also used CCSM to uncheck "Maximize Vertically if Screen edge hit" as described in How to disable the auto resizing of Windows when you touch the top or bottom. I set the Grid Snapback Threshold to 0 for the top edge in CCSM and top_edge_threshold to 0 in gconf-editor (this was my idea; I don't know if it makes sense or not). Finally I used CCSM to disable the "Grid" feature entirely. At each step there was no change in behaviour and now I find myself stuck with this annoying feature. What else can I try?

  • Personally, I consider this a feature.

I use 16.04 Gnome Classic, metacity.

Managed to disable the irritating 'auto resize' problem:

  1. Open 'dconf Editor' ;

  2. Search for edge-tiling

  3. Uncheck the corresponding box.


I think the hotcorners tool in Unity Tweak Tool may work for you:


Disclaimer: I have never used this app, so I am not entirely sure what its features are.

  • That looks like exactly what I want, but unfortunately, that's for Unity; I'm using the Gnome Classic desktop.

I am running a similar config, with Gnome Classic, and hit the same problem.

Guesswork led to this gconf-editor solution. Change

/apps/compiz-1/plugins/snap/screen0/options/avoid_snap [0]


/apps/compiz-1/plugins/snap/screen0/options/avoid_snap [1]

Use the keyboard shortcuts for window positioning instead of the mouse.

CTRL-ALT-(Numpad)8 for window to top, CTRL-ALT-(Numpad)2 for window to bottom, etc.
