Jupyter qtconsole cursor type and image size config

Hi,

I am using win10 and jupyter version info as below:
jupyter core : 4.5.0
jupyter-notebook : 6.0.1
qtconsole : 4.5.5
ipython : 7.8.0
ipykernel : 5.1.2
jupyter client : 5.3.3
jupyter lab : not installed
nbconvert : 5.6.0
ipywidgets : 7.5.1
nbformat : 4.4.0
traitlets : 4.3.2

I wish to change jupyter qtconsole cursor to a more bigger one and change the image output to match full width by default.

I try below config but it doesn’t work:
.jupyter\jupyter_qtconsole_config.py
c.JupyterQtConsoleApp.display_banner = False
c.JupyterConsoleApp.confirm_exit = False
c.ConsoleWidget.console_width = 120
c.ConsoleWidget.console_height = 40
c.ConsoleWidget.font_size = 18
c.InlineBackend.rc = {‘font.size’: 10, ‘figure.figsize’: (12.0, 8.0), ‘figure.facecolor’: (1, 1, 1, 0), ‘savefig.dpi’: 72, ‘figure.subplot.bottom’: 0.125, ‘figure.edgecolor’: (1, 1, 1, 0)}

The last line doesn’t work (I copied it from ipython config before).
