Sometimes I open a new window in a program (such as a new notebook in Mathematica), and the title bar of the window appears above the screen, so I cannot drag the window around.

What can I do when this happens? Is there a command I can use in the terminal to maximize the window, or to change its location?


Hold down "Alt", left click and hold in the window, and then move the mouse around. That should grab the window and let you move it.

  • +1 Thanks! That works. And it's way simpler than I expected.

    Much easier than my prior method: click on the window and press alt+space to make the window control menu appear. Aug 7 '14 at 14:48
  • Didn't know about alt+space. Perhaps it is time for me to take another look at the keyboard shortcuts (just hold the super key for a bit).

  • What to do with windows that captures all the mouse input and keyboard input? For example how do you do that with a virtualbox window? Pressing alt+space, or alt clicks sends the keystrokes to the guest.

  • This trick seems to work well for LXDE, what implements this? Is this built in to the X window system itself or is it a DE feature?

In Gnome 3, the default is to use the Super aka Window key with mouse drag. In many previous Ubuntu window managers, it was the Alt key with mouse drag. There are a variety of ways to change this keybinding. See How to enable dragging windows with alt-click in gnome 3 / gnome shell - Super User
