jupyter qtconsoleのコンフィグです。
以下のページから引っ張ってきました。

使い方

~/.jupyer/jupyter_qtconsole_config.pyを作成して以下をコピペし、:を=に変えます。
コメントアウト#をc.に変えてます。

例えば

c.JupyterQtConsoleApp.hide_menubar : True  # メニューバー隠す
c.JupyterWidget.syntax_style = 'monokai'  # monokai(背景黒)スタイルにする

こうすることでqtconsoleを立ち上げたとき、常にメニューバーなしの背景黒色のウィンドウが立ち上がります。

# at the command line when you start it.

#     Default: ``''``

#     JSON file in which to store connection info [default: kernel-<pid>.json]

#     This file will contain the IP, ports, and authentication key needed to connect
#     clients to this kernel. By default, this file will be created in the security dir
#     of the current profile, but can be specified by absolute path.

#     Default: ``True``

#     Whether to automatically execute on syntactically complete input.

#     If False, Shift-Enter is required to submit each execution.

#        Similar to 'hsplit', except that a vertical splitter is used.
#     'custom'
#        No action is taken by the widget beyond emitting a
#        'custom_page_requested(str)' signal.
#     'none'
#        The text is written directly to the console.


# ConsoleWidget.width : Int
#     Default: ``81``

#     The width of the console at start time in number

#     will be appended to the end the command.


# JupyterWidget.editor_line : Unicode
#     Default: ``''``


#     The editor command to use when a specific line number is requested. The
#     string should contain two format specifiers: {line} and {filename}. If
#     this parameter is not specified, the line number option to the %edit
#     magic will be ignored.

#     Should we autorestart the kernel if it dies.

# KernelManager.kernel_cmd : List
#     Default: ``[]``

#     The Popen Command to launch the kernel.
#     Override this if you have a custom kernel.
#     If kernel_cmd is specified in a configuration file,
#     Jupyter does not pass any arguments to the kernel,
#     because it cannot make any assumptions about the
#     arguments that the kernel understands. In particular,
#     this means that the kernel does not receive the
#     option --debug if it given on the Jupyter command line.


# Session.buffer_threshold : Int

#     Threshold (in bytes) beyond which an object's buffer should be extracted to avoid pickling.

# Session.item_threshold : Int
#     Default: ``64``

#     The maximum number of items for a container to be introspected for custom serialization.
#     Containers larger than this are pickled outright.

#     Metadata dictionary, which serves as the default top-level metadata dict for each message.

# Session.packer : DottedObjectName
#     Default: ``'json'``

#     The name of the packer for serializing messages.
#     Should be one of 'json', 'pickle', or an import name

#     The UUID identifying this session.

# Session.signature_scheme : Unicode
#     Default: ``'hmac-sha256'``
