Just starting to use Unity with 11.10, and obviously there are a lot of changes to get used to. One of the most annoying is the habit it has of trying to maximize a window when I drag it up against the top bar to position it.

How do I disable this behaviour? I assume there's a toggle in CCSM somewhere, but I can't find it.

this works for 11.04 classic desktop as well and has nothing to do with unity. – Alvar Nov 18 '11 at 21:08
Great, I have been looking for how to disable this annoyance for so long, just didn't know what it was called! Even posted the same question which went unresolved. – Marcos Apr 19 '12 at 20:48

If you simply want to turn off this feature then run the following in a terminal:

gconftool-2 --set /apps/compiz-1/plugins/grid/screen0/options/top_edge_action --type int 0

Alternatively - with a GUI, use gconf-editor:

Compiz configuration options

Great, this is exactly what I was looking for, thanks. I like the grid keypad actions, so just setting the thresholds to 0 gives me the behaviour I want. – unit3 Oct 26 '11 at 20:01
While it's nice to have a non-compiz answer, I personally prefer BinaryLife's answer -- the GUI version. It exposes more related settings and you're not poking at numeric values. – Jeff Ward Apr 5 at 15:33

You can disable it from ccsm : Click to install

Go to Windows management--> Grid --> Edges --> Re-size Actions

Top Edge: change it to none.

Anytime,Glad to help! – Binarylife Jun 4 '11 at 18:03
Very good. I switched off all edges to get rid of that when I pull the window to another desktop. – Bevor May 15 '13 at 15:42
