Ubuntu 에서 <Ctrl><Alt>Up, <Ctrl><Alt>Down short-cut 제거

Ubuntu 에서 <Ctrl><Alt> Arrow(Up, Down) key 가 Workspace 전환에 사용된다.

이 Key가 VDI Windows 가상 환경의 applicaton에서의 short-cut과 충돌이 나면 아래와 같이 찾아서 제거 한다.

$ gsettings list-recursively | grep org.gnome.desktop.wm.keybindings | grep Control | grep Alt
org.gnome.desktop.wm.keybindings cycle-panels ['<Control><Alt>Escape']
org.gnome.desktop.wm.keybindings cycle-panels-backward ['<Shift><Control><Alt>Escape']
org.gnome.desktop.wm.keybindings move-to-workspace-down ['<Control><Shift><Alt>Down']
org.gnome.desktop.wm.keybindings move-to-workspace-left ['<Super><Shift>Page_Up', '<Super><Shift><Alt>Left', '<Control><Shift><Alt>Left']
org.gnome.desktop.wm.keybindings move-to-workspace-right ['<Super><Shift>Page_Down', '<Super><Shift><Alt>Right', '<Control><Shift><Alt>Right']
org.gnome.desktop.wm.keybindings move-to-workspace-up ['<Control><Shift><Alt>Up']
org.gnome.desktop.wm.keybindings switch-panels ['<Control><Alt>Tab']
org.gnome.desktop.wm.keybindings switch-panels-backward ['<Shift><Control><Alt>Tab']
org.gnome.desktop.wm.keybindings switch-to-workspace-down ['<Control><Alt>Down']
org.gnome.desktop.wm.keybindings switch-to-workspace-left ['<Super>Page_Up', '<Super><Alt>Left', '<Control><Alt>Left']
org.gnome.desktop.wm.keybindings switch-to-workspace-right ['<Super>Page_Down', '<Super><Alt>Right', '<Control><Alt>Right']
org.gnome.desktop.wm.keybindings switch-to-workspace-up ['<Control><Alt>Up']

 

위 명령어로 확인한 결과 <Control>Alt>Down, <Control><Alt>Up key 가 switch-to-workspace-down, switch-to-workspace-up 에 정의 되어 있다.

아래 명령어로 삭제 한다.
