Extended-GTK3-nocsd

extgtk3-nocsd is a wrappper for gtk3-nocsd module used to disable the client side decoration of Gtk+ 3 per application

Introduction:

Since Gtk+ 3.10, its developers added a so-called header bar or custom title bar. With this and the client-side decoration, the original title bar and window border provided by the window manager are disabled by Gtk+. The worst part, is that it breaks down some window managers or composers. See a example:

Unfortunately, the Gtk+ developers decided to be against the existing standards and provide "no option" to turn it off. Thanks to PCMan's gtk3-nocsd, we still have a way to (partially) turn it off. Window manager (title bar and window border) can be re-enabled. But isn't seamless as you can see:

Note the duplication of application title and window icon

The extgtk3-nocsd fix it by overriding GTK 3 config dir, so the result looks more naturally:

How to use:

• Install gtk3-nocsd (usually by installing libgtk3-nocsdpackage)
• Download the wrapper: wget https://git.io/fjGRR -O extgtk3-nocsd
• Turn executable: chmod +x extgtk3-nocsd
• Move to /usr/bin: sudo mv extgtk3-nocsd /usr/bin/
• Use the command extgtk3-nocsd applicationfor example extgtk3-nocsd evince

To have all Gtk+ 3 apps (of current user) use this:

Note: If you installed gtk3-nocsd from your package manager you don't need do these steps, only run:

extgtk3-nocsd

---

• Install gtk3-nocsd (usually by installing libgtk3-nocsdpackage)
• Run script without parameter:extgtk3-nocsd

You will see some errors, ignore them

• Do these steps:

Export some environment variables in your ~/.bashrc:

GTK3_NOCSD=$(ldconfig -p | grep libgtk3-nocsd.so | awk '{print $4}')
export GTK_CSD=0
export LD_PRELOAD="${GTK3_NOCSD}${LD_PRELOAD:+:$LD_PRELOAD}"

On Arch Linux, you should use ~/.xsession instead of ~/.bashrc for the CSDs to be disabled properly.

On Debian-based systems with graphical login, instead modify (or create) ~/.xsessionrc and add the code:

  if [ -n "$STARTUP" ]; then
    BASESTARTUP=${STARTUP%% *}
    BASESTARTUP=${BASESTARTUP##*/}
    if [ "$BASESTARTUP" = x-session-manager ]; then
      BASESTARTUP=$(basename $(readlink /etc/alternatives/x-session-manager))
    fi
    if [ x"$BASESTARTUP" = x"${BASESTARTUP#gnome-session}" ] ; then
      GTK3_NOCSD=$(ldconfig -p | grep libgtk3-nocsd.so | awk '{print $4}')
      export GTK_CSD=0
      STARTUP="env LD_PRELOAD=${GTK3_NOCSD}${LD_PRELOAD:+:$LD_PRELOAD} $STARTUP"
    fi
  fi

Re-login to make the environment variables take effect.
