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?

Answer 1

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.
