Fixing the error "The global keyboard shortcut Control+Alt+D cannot be registered"

On Debian 10 "buster" with LXQT desktop, a warning appears when starting a user session from lxqt-panel that the keyboard shortcut cannot be registered "Ctrl+Alt+D".

The cause of the problem is a conflict between the programs "Global Keyboard Shortcuts" and the window manager OpenBox for the keyboard shortcut "Ctrl+Alt+D".

Methods proposed on the Internet to solve this problem are either destructive to the operating system (full shutdown programs Global keyboard shortcuts) or difficult for most users (editing openBox window manager rc.xml file). The method I propose does not have these disadvantages and is suitable for users of any level of training.

Solution:

Click "Start" - "Settings" - "LXQT Settings" - "LXQT System Settings".
Open the window item "LXQT Settings" -"Keyboard shortcuts".
Assign to action "Show desktop" combination "Shift + Control + D".
To do this:
*Scroll down the list to "Show desktop"
- Double-click on the line "Show desktop" or select this item and click on the " buttonEdit".
  Click in the form field "Keyboard shortcut" (time countdown begins)
  Press keys Shift+Control+D(the countdown will stop and a new keyboard shortcut will be added to the field)
- Confirm changes:"OK", "Close".

This method of solving the problem is also convenient because it works when controlling the computer remotely. For example, using RDP or VNC. At the same time, the action "Shift + Control + D" "Minimize all windows and show desktop" is triggered on the remote computer, and when clicked "Alt + Control + D" the desktop of the local computer is shown.
