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.
Install packages required to run the script.
sudo apt-get install wmctrl x11-xserver-utils
Run the script with:
$ chmod +x ./offscreen-window-restore.sh
$ ./offscreen-window-restore.sh
