Ubuntu – How to disable workspace higlighter popup during switching workspace

You could try this, if you haven't installed compiz settings manager, then do so by running:

sudo apt-get update
sudo apt-get install compizconfig-settings-manager

Once it's installed, click System > Preferences > Compiz Settings Manager

Then go to Focus & Raise Behaviour > General and set Focus Prevention Level to Off

Tested on Ubuntu 16.04.

If you're using Compiz (run wmctrl -m if not sure), wmctrl only sees 1 desktop (2nd field of wmctrl -l, ie 0) but you can use the geometry (-G) option to know what window is on what virtual desktop. All windows in your current desktop will have an x-position between 0 and your screen's width. Same for the y-position between 0 and your screen's height. So you can use something like that

#!/bin/bash

SCREEN_W=$(xwininfo -root | sed -n 's/^  Width: \(.*\)$/\1/p')
SCREEN_H=$(xwininfo -root | sed -n 's/^  Height: \(.*\)$/\1/p')

NAME='Navigator.Firefox'

wmctrl -xlG | awk -v W="$SCREEN_W" -v H="$SCREEN_H" -v NAME="$NAME" '$7==NAME && $3>=0 && $3<W && $4>=0 && $4<H {print $1}' | while read WINS; do wmctrl -ia "$WINS"; done

exit 0

You can hardcode your screen's width and height if you will, and NAME if you want a one-liner. Im not sure how you want to handle multiple windows matching NAME. That will focus them all.

For metacity, desktop number of windows can be found using wmctrl -l and grepping the 2nd field.
