Restart X

  • The easiest way to restart X-windows is to simultaneously press ctrl-alt-backspace. Note: this will instantly kill X-windows and any programs running within it, like your window manager and probably everything else. There will be no confirmation.
  • Note: Since Ubuntu 10.04 the keystroke "ctrl" + "alt" + "backspace" has been disabled. The default shortcut is now "alt"+"print screen"+"k" (More info is here at restart X server. )
