How to disable the dynamic transparency effect of the dock while maximizing a window?

Question

How to disable this effect? Check the panel and dock's transparency on Ubuntu 17.10. Difference between the panel's transparency before and after maximizing any windows:

• Before maximizing a window (which I like):

  

• After maximizing the window (which I don't like when it happens):

  

I don't want that effect after maximizing a window. Is it possible to make change to the gnome's panel like Xfce's panel?

Solution

Transparency of Ubuntu Dock

Open Terminal and run the following command first to allow custom alpha values for Ubuntu dock

gsettings set org.gnome.shell.extensions.dash-to-dock customize-alphas true

Then run the following command to obtain the alpha value of the dock as in the first screenshot

gsettings get org.gnome.shell.extensions.dash-to-dock min-alpha

The output is say 0.2.

Finally run the following to set the maximum alpha value (i.e. when a window is maximised)

gsettings set org.gnome.shell.extensions.dash-to-dock max-alpha 0.2

Then log out and log in again.

Transparency of the top bar

You may use a GNOME shell extension called Dynamic Panel Transparency to achieve fixed transparency of the top bar.

1. Install the extension from the link above.
2. Reload the page. A settings icon should appear.
3. Click on the settings icon. A window should pop up.
4. Go to the "Background" tab and toggle on "Enable custom opacity".
5. Set low values (say 30% or 40%) for both "Maximized Opacity" and "Unmaximized Opacity".
   
6. Log out and log in again.

My output is 0.20000000000000001 for this command: gsettings get org.gnome.shell.extensions.dash-to-dock min-alpha ...so i should type this?: gsettings set org.gnome.shell.extensions.dash-to-dock max-alpha 0.20000000000000001? or 0.2?

@Sss Yes, you can set any value between 0 (completely transparent) and 1 (completely opaque). For the sake of consistency it's better to keep min-alpha and max-alpha same.
