Hide Specific Running Applications from Dock (Side Bar) on Ubuntu 18.04

  • 772

I want to make secret recordings and I would like to hide only one application, for example, Cheese, which makes video recording. Does anyone know how to do this?

enter image description here

gnome-shell ubuntu-dock

  1. Do:

    xprop | grep "CLASS"

    and click on the window you want to remove from taskbar.

    This will return something like

    WM_CLASS(STRING) = "name", "name"

    Install wmctrl

    sudo apt install wmctrl

    Make a program startup script or run once, depending on your preference:

    wmctrl -x -r name.name -b add,skip_taskbar

  2. It is not a definitive solution but it works. I used the dconf-editor program to hide running applications, as shown in the image. Those that are running but I do not want to hide, as is the case of Google Chrome that appears in the image, I fixed it on the dock.
