I'm frustrated that this was removed/altered in gnome-shell3. There are certain key bindings for resizing and moving windows like alt+right click etc, that I'd like back. I've tried to use the system settings but to no avail. Has anyone else worked with this and got it to work?
In more recent gnome versions (e.g., gnome-shell), you need to use this instead:
gsettings set org.gnome.desktop.wm.preferences resize-with-right-button true
Gnome defaults to using the Super ("Windows") key for window actions, so the above alone will enable moving (super-leftdrag) and resizing (super-rightdrag). To use the Alt key instead of the Super key do:
gsettings set org.gnome.desktop.wm.preferences mouse-button-modifier '<Alt>'
(note that using the Alt key for window operations will interfere with some apps, like Inkscape, that use alt-click and alt-drag for app related actions)
You can use
gconf-editor for this. Enable this setting:
In Cinnamon (rather than Gnome3) the corresponding setting is:
gsettings set org.cinnamon.desktop.wm.preferences resize-with-right-button true
Or find the corresponding path in
mouse-button-modifier under the same path if you'd rather use the
Super key instead of the
Alt key for move/resize behaviour (useful for conflicts with other apps such as blender).
Additionally to using
gsettings and instead of using the deprecated
gconf-editor, you can install the newer
dconf-editor and find and change relevant keys there. Searching "resize with" will find its key regardless of used WM.
If you install GNOME Tweaks, there's an option to "Resize with secondary click". Checking it will enable Super+RMB to resize windows.
