It is common to have two equally separated windows by either dragging each window to one side of the screen or Ctrl+Super+/, but I want to divide my screen into four quarters.

I have encounterd many situations in which I had to switch windows between three or four. It would be sometimes easier to debug any code if I could have a screen with four equally divided windows so that I could see the entire system with one look.

    Ubuntu has many different window managers available; maybe you would be interested in trying out a tiling window manager. I like awesome. – Nate Eldredge Nov 24 '15 at 16:51
  • No, it's not possible to have four equally sized windows. As soon as their size is within one pixel, your computer will immediately shut down. /s – user253751 Nov 25 '15 at 8:23

It is possible, as you can see from this example with four gnome-terminal windows:

example

I did not manually resize and position the windows, which I could have done, but just dragged them into the corners of the screen to format them automatically. It's the same procedure as you described with placing a window into the left or right half by dragging it to the respective border of the screen. There are also custom keyboard short-cuts to achieve this.

You can set up whichever method you prefer or both.

However, the corners are by default configured the same way as the side borders and the short-cuts are probably disabled, so we have to change these settings.

Therefore we need the CompizConfig Settings Manager Install compizconfig-settings-manager.
You can also install it from the terminal with the command below:

sudo apt-get install compizconfig-settings-manager

After that, launch ccsm.

Navigate to the category Window Management and select the Grid plug-in. Go to the Corners / Edges tab and you should see the following settings:

ccsm > Grid > Corners/Edges

Set all corner options according to my example above, so that when you drag a window e.g. into the upper left corner, it will get resized and placed into the top left quarter of the screen.

You can also set up keyboard short-cuts to place windows into the grid. Switch to the Bindings tab and select the short-cut key combinations you prefer. I opted for Ctrl+Alt+NumPad 1-9 to put the windows into the respective screen halves or corners. See my example below:

ccsm > Grid > Bindings

All your changes take effect immediately, so just close the ccsm window.

Now you can start dragging windows into the corners:

    Beautiful examples of commands run in the terminals – Viktor Mellgren Nov 25 '15 at 9:57
  • this answer works when using compiz with xubuntu too. – Tim Richardson Dec 29 '17 at 5:13

You can do this as well with the Unity Tweak Tool.

Install it with the terminal command below or by clicking here: unity-tweak-tool Install unity-tweak-tool

sudo apt-get install unity-tweak-tool -y

Once you installed this tool, open it and go to Window Snapping and then you can configure the window snapping on Ubuntu.

Unity tweak tool

  • Why do you use the version from a PPA? unity-tweak-tool is also available from the universe repository. That version is probably more stable. – Byte Commander Nov 25 '15 at 15:03
  • Yes, you're right. you can use that version too. – Carlos Gómez Nov 26 '15 at 17:55

    @RahulRaj I do not know if there is a link that explains how to configure the windows snapping configuration, but I think it is a matter of choice for the setting it. for example , I like that when I drag a window to the top left corner , the window becomes 1/4 of the screen, and the same for the corners ( upper right , lower right , lower left ) , you can try play with the settings, it is not rocket science. You will learn faster if you try . Sorry for my english it's not my main language – Carlos Gómez Nov 26 '15 at 19:17

There is a little application called x-tile that can organize windows in several different ways, including the way you want (tile all quad). Make sure to manually install python-appindicator (missing depency -- filed a bug for it).

Use ShellTile to get equally sized windows on Ubuntu 18.04.1 LTS (Bionic Beaver).

The generic keyboard settings dialogue allows shortcuts to be set for view split on left or right.

Additional shortcuts can be added with the + button, although I do not know what the commands would be.
