How can I disable Alt-Scroll zoom in Xubuntu 14.04?

There is an easy way, without losing the moving windows feature.

1. Open Settings Editor
2. Go to Channel xfwm4
3. Disable Property zoom_desktop

To activate or deactivate, there is also another option in Window Manager Tweaks. Under Compositor, the option to enable or disable display compositing will also enable or disable desktop zoom.

Here is how disable this feature from the command line:

xfconf-query --set false --channel xfwm4 --property /general/zoom_desktop

If you get this message:

Property "/general/zoom_desktop" does not exist on channel "xfwm4".
If a new property should be created, use the --create option.

then run this command instead:

xfconf-query --create --type bool --set false --channel xfwm4 --property /general/zoom_desktop
