According to Canonical's proposal, Linux desktop should change the GNOME and KDE Desktop notification systems. Currently, mark Shuttleworth posted a new notification demonstration for uBuntu 9.04 by the Ubuntu Desktop experience engineering team on his blog.
From the video, this message notification system is very effective, but it is similar to the third-party notification system Growl on Mac OS X, shuttleworth believes this method can fill the gap between Linux desktops and applications. In addition, they have had early talks with some OEM partners, hoping to pre-install uBuntu 9.04 on Netbook, and these systems will have this dazzling new desktop effect.
At present, these codes still need to be further improved and work in accordance with freeyuntop.org specifications. However, the objection points out that the implementation of the new method needs to solve several problems. First, the software update MUST be bundled with the existing notification system. In addition, the new design needs to run the combined manager, linux users are not familiar with this.
