In gnome-shell there is an extension that removes the window borders, close buttons, title bar, etc on maximized windows to save screen real estate.

How can this behavior be replicated in KDE?

Note: In recent versions of KDE Plasma (5.18+), Latte dock is interfering with the particular setting described in this answer (After every restart, the user has to run the command in this answer once again, because Latte overwrites the configuration file). The workaround is to let Latte dock manage the borderless window configuration. See this answer for more details.

To remove the borders of maximized windows in KDE Plasma 5, run the following commands:

kwriteconfig5 --file ~/.config/kwinrc --group Windows --key BorderlessMaximizedWindows true
qdbus org.kde.KWin /KWin reconfigure

This is equivalent to doing the following:

  1. Edit the file ~/.config/kwinrc to add the line:


    under the [Windows] section, so that it looks something like this:


    In older versions of KDE, the file may be located at:


  2. Restart KWin by running:

     kwin --replace

    If that does not work, try one of the following, depending on which display server you are using:

     kwin_x11 --replace
     kwin_wayland --replace

Go crazy and maximize every window in sight! Remember that you can unmaximize them from the window menu (Alt + F3) or from the task manager in your panel. If quick tiling is enabled (System Settings → Desktop → Screen Edges → Window Management), you can also use Alt + Left mouse button to unmaximize windows by dragging them.


  • So much easier to do in XFCE4…

  • Great answer! Thank you very much. I wonder how come this is not configurable on some UI. Feb 16, 2019 at 15:37
  • I used to use this KWin script but modified to apply to all windows store.kde.org/p/1199110 Nice that the same effect is now built in as a setting, I wonder why there's no GUI toggle for it in the system settings. Thanks for the tip!

  • Can I achieve "no borders" for certain windows too? I want to remove the borders of the terminal window

In Kubuntu 18.04, one can toggle borders (including the titlebar) and the maximized state of windows relatively simply.

In System Settings, choose Shortcuts > Global Shortcuts > KWin. In there, scroll to Hide Window Borders and set a shortcut. I chose Meta+D and clicked Apply.

Toggle borders Now I can toggle borders by just pressing Meta+D.

Still, while in System Settings > Shortcuts > Global Shortcuts > KWin (in Kubuntu 18.04.1 LTS, Kwin corresponds to System Settings Module), scroll further down to Maximize Window. Here, I chose Meta+X and clicked Apply.

Maximize Windows Now I can toggle between a non-maximized window and a maximized one by just pressing Meta+X.

Obviously, I can use both Meta+D and Meta+X on the same window whenever I want.

Go to System Settings->Window Management->Window Rules->New..

Add Window class choose “Regular Expression” from the drop-down and put “.*” in the input.

Click the Appearance & Fixes tab. Check “No titlebar and frame”, select “Force” from the drop-down, and select the “Yes” radio.

Save and close everything.

Your title bars will disappear but you will need to use the keyboard to close windows, minimize...



In several applications --- Firefox, Google Chrome, Geany, Konsole are examples --- you can toggle borders (including the titlebar) and the full screen state of windows with the function key F11.

This works in Kubuntu (I tested in Kubuntu 18.04.1 LTS right now). F11 works also in standard Ubuntu and the other Ubuntu community flavours.

  • I think what F11 does depends on the active window's application. If it's Firefox or Chromium browser, F11 makes the window full-screen. Same with Geany. But LibreOffice and Kate, for example, don't behave that way.

  • @DKBose, That's right. Some application programs grab F11 for some special task. So 'use F11, when in works, it is convenient', otherwise your method is good (I upvoted it).

  • @DKBose, Thanks for the edit :-) I made a small modification, but I the main part and spirit of your modification of my answer is still there.
