=== Off-Screen Window Restore

Source : https://github.com/mezga0153/offscreen-window-restore

A simple shell script that moves off-screen windows back.

This script was made to fix a bug in unity where if you have multiple monitors, when they wake up after being off some windows move off-screen.

<code bash>
sudo apt-get install wmctrl x11-xserver-utils
</code>

''offscreen-window-restore.sh''
<code bash>
#!/bin/bash
#
# This script moves back windows that have been moved off screen
