The first thing that freaked me out were Ubuntus undismissable and fading bubbles.
Use leoliks repo to install libnotify-bin.
sudo add-apt-repository ppa:leolik/leolik sudo apt-get update sudo apt-get upgrade sudo apt-get install libnotify-bin pkill notify-osd
Now to notifyosdconfig. To configure the notifications you need to install this config tool by adding this repo:
sudo add-apt-repository ppa:amandeepgrewal/notifyosdconfig
This repo is a bit outdated so the latest distribution which is currently working is utopic and you have to trust it manually.
You need to edit the file /etc/apt/sources.list.d/amandeepgrewal-ubuntu-notifyosdconfig-zesty.list
deb [trusted=yes] http://ppa.launchpad.net/amandeepgrewal/notifyosdconfig/ubuntu utopic main
Save it and run this:
sudo apt-get update sudo apt-get upgrade sudo apt-get install notifyosdconfig
