ubuntu设置点击图标最小化:

guoshipeng@tianyi510s:/usr/local$ gsettings range org.gnome.shell.extensions.dash-to-dock click-action
enum
'skip'
'minimize'
'launch'
'cycle-windows'
'minimize-or-overview'
'previews'
'minimize-or-previews'
'focus-or-previews'
'focus-minimize-or-previews'
'quit'

设置为minimize:

guoshipeng@tianyi510s:/usr/local$ gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize'
