All windows are still draggable using their headers, except for Firefox. Firefox lost its window decorations and can be neither dragged nor resized.

Is it possible to restart a window manager and/or to check its logs?

  • What is Alt+drag supposed to do? What do you expect it to do? Did you install/remove something? Please give as much information as possible if you are having an issue.

  • alt-drag lets you move windows from wherever you click on them, rather than just the window headers. Very useful for applications with fixed window sizes on small screens.

Alt+Drag

On my install (Freya) the default key for this functionality is actually Super (meta/windows key). You can change this in dconf-editor by navigating to org.gnome.desktop.wm.preferences and setting mouse-button-modifier to <Alt>

Gala (Window Manager)

The command to respawn the window manager is DISPLAY=:0 gala --replace &. Note that you should do this from a VT (Ctrl+Alt+F1) rather than a gui terminal so the gala process doesn't end when you close said terminal.

    I know this is a little bit late but you could create a bash script file that has DISPLAY=:0 gala --replace & in it. Just chmod +x it and then run the script from the file manager. So, no more need for VT.
