Is there any button in Ubuntu like in windows which is present in right-bottom corner to minimize all windows?
If it is there please tell me, it will be of great use.
Press Ctrl+Super+D at the same time. It is the shortcut to minimize all windows.
You can define hot-corner with custom command using compizconfig-settings-manager and wmctrl package to minimize all windows(show the desktop)
From man wmctrl
-k ( on | off )
Turn on or off the window manager's "show the desktop" mode (if
the window manager implements this feature).
Install
compizconfig-settings-manager
and wmctrl
using
sudo apt-get install compizconfig-settings-manager wmctrl
Open compizconfig-settings-manager
by entering ccsm
in dash.
Search for Commands in ccsm window .
In Command line 0 type
wmctrl -k on
