Remove title bar and borders on maximized windows in Kubuntu

Solution 1:

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:

   BorderlessMaximizedWindows=true
   

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

    [Windows]
    BorderlessMaximizedWindows=true
    ActiveMouseScreen=true
    AltTabStyle=KDE
    AutoRaise=false
    AutoRaiseInterval=750
    BorderSnapZone=10
    CenterSnapZone=0

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

   ~/[.kde|.kde4|.kdemod4]/share/config/kwinrc

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.

Solution 2:

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.

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.

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.

This how your desktop will look after that with minimize,maximize and close buttons on the top right without borders

Solution 4:

F11

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.

Solution 5:

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...
