On my previous post I was trying to install Jackalope's notify-osd on Intrepid and was waiting  for download process to finish, and now a post later it's a success! Thanks to easy to follow manual from softpedia.
Although the manual can look complicated at first, it's not, just follow the steps, one at a time and you're there.
Here's how it looks on my system.

keyword : 9.04 notification on 8.10 | notify-osd
