I cannot control the window size

Hello,

I am using ubuntu 18.04.

I want to move my matlab window or make small, but as you can see there is no such button.

When I undocked the editor, I could find it. but not in main window.

I got error messages when I launch MATLAB.

Gtk-Message : failed to load module "overlay-scrollbar"

Gtk-Message : failed to load module "canberra-gtk-module"

Are they making problems?

Here are the screen shots. The right up side.

On Editor there, I can close, minimize and re-size the window. But not in the main window. (2nd screen shot)

Best regrads,

Hey Jian,GTK is a tool for cresting GUIs in GNOME environment.

you may try installing these gtk modules on your ubuntu system.

sudo apt-get install --reinstall overlay-scrollbar-gtk2
sudo apt install libcanberra-gtk-module libcanberra-gtk3-module

Then restart your system to see if it works for you.
