Restore the Ctrl + Alt + Num Pad 4 and 6 window positioning commands?

Solution 1:

Install compizconfig-settings-manager . Search for "compiz" in the Unity Dash, or start with ccsm from the commandline.

Warning

CompizConfig Settings Manager (ccsm) is an advanced tool, and not all of its options are completely compatible with Unity. As such, CCSM has been known to sometimes break users' desktops. Please use caution and know that you are taking a risk by following this answer or any other answer that recommends the use of CCSM. In the event that following this advice does break Unity, please see this question for instructions on how to reset it.

Find the Grid plugin:

Click on the key binding you want to change, click on Grab key combination, and press the keys you'd like to use.

Solution 2:

The shortcuts have been replaced with Ctrl+Super+Left and Ctrl+Super+Right. At the moment, Compiz (Unity's backend) does not support multiple shortcut keys for one action. This may change in the future.

Hold down Super to see them all:

Solution 3:

I too had this problem.

You'll need to install compizconfig-settings-manager (CCSM).

In CompizConfig Settings Manager go to "Grid" (near the bottom under Window Management):

Set the bindings (which was not set for me either) to Put Left as Ctrl+Alt+4, and Put Right as Ctrl+Alt+6:

I too would like to see this as a standard put into a patch for put window using number pad.
